EXECUTIVE SUMMARY
0.1 PROJECT DESCRIPTION
Tamu - Kyigone - Kalewa road is of intermediate lane width and passes through plain and hilly terrain. The road is generally in good condition except the bridges which are old steel bridges of single lane width and are proposed to be replaced by two lane wide bridges for Class 70 R loading
The project road starts at km 0.00 (93.0 milestone) at India Myanmar border near Tamu (Bridge no. 1) and ends at km 149.70 (0.0 milestone) at Kalewa.
The alignment from Km 0.000 to Km 121.690 i.e. between Tamu and Kyigone is passing through Plain and Rolling terrain. From Kyigone to Kalewa the project road is passing through hilly terrain. The land use observed along the alignment section is predominantly agriculture and open lands and some sections are passing through settlement areas along the road.
0.2 ENGINEERING SURVEYS AND INVESTIGATIONS
Based on the requirement enumerated in the terms of reference for “Preparation of Feasibility Report for Construction of Bridges including Approaches on Tamu – Kyigone – Kalewa Road Section from km 0.00 to km 149.70 in Myanmar” consultants had carried out engineering surveys and investigations as given below: • Topographical Survey • Road Inventory and Condition survey (for bridge approaches) • Inventory of 71 steel bridges • Inventory of culverts and other structures falling on bridge approaches • Pavement Condition Survey • Soil and Material investigations • Hydrology and Drainage Studies • Traffic Surveys and Analysis • Material Investigation • Geo-Technical Investigations
Topographical Survey
Detailed topographical survey of all natural and manmade topographical features has been carried out by picking up their x, y and z coordinates using Total Stations having automatic data recording devices with appropriate feature codes attached to each point. Survey corridor is 30m on either side of the center line of existing road.
In general, these include:
• Road center line. • Pavement edges. • Outer shoulder edges. • Toe lines of fills and cuts. • Longitudinal and transverse drains/ ditches. • Bridge locations and Details. • River Channel locations along with river cross-sections.
All man-made and natural topographical features were surveyed, including:

MEA 0-2
• Water sources, Ponds etc. • Culverts with their type and number • Electric and telephone lines • Huts, Buildings, fences, stairs, hand pumps, bore wells, wells • All Buildings were collected with suitable codes depending upon its classification like
residential, commercial, educational, health Center, industrial, religious etc. • Oil and gas pipe lines • All trees with girth greater than 0.3 meter.
At locations, where existing alignment cross other roads, the survey was extended to 100 to 200 m on either side of the road center to allow for the geometric improvements. Cross sections at every 50 m interval in flat terrain and at lesser interval on undulating terrain or horizontal curves were also taken using Total Stations.

• In many sections horizontal alignment has S curves and sharp curves not conforming to IRC Standards.
• At many locations vertical curves not conforming to IRC standards. Frequent rise grades and fall grades has been observed in many section.
• Drainage along the stretch is predominantly non-existent except in hilly stretch where they are partially functional.
• Field observations, secondary data and Local inquiries indicated that some road stretches get submerged during heavy rains.
• There is no clear demarcation at site of the existing right of way more over there are encroachment at many places.
• The existing ROW varies from 30m to 70m all along the project highway.
Hydrology and drainage
As per local enquiry and visual inspection submergence was observed at 8 number of bridges. Detailed hydraulic calculations of all bridges has already been submitted in stage “KD3: Report on soil characteristics, sub-soil and hydraulic investigation, GAD for bridge and other structures”

Soil and Material Investigation
Subgrade sampling has been carried out in accordance with IRC requirements strictly adhering to sampling requirements. From each source pits of 1m x1 m were dug and samples of 40 to 50 Kg are collected to establish the suitability of the material for various layers namely embankment and sub grade. The samples thus collected were subjected to following laboratory tests:
Grain size analysis : As per IS: 2720(part 4)

0.3 ENGINEERING DESIGN AND PROPOSALS
To accommodate the requirement for 2 lane carriageway with earthen shoulders configuration of the project as per requirements, the Consultant has optimized the various requirements and tried to accommodate the proposed bridge location along with approaches within the existing ROW. The available ROW varies from 30m to 70m along the project road. Geometric improvements / realignments for approaches have been proposed within available ROW. Except at few bridges, new bridges have been proposed at same locations of existing steel bridges. At few locations bridge locations has been shifted to improve the geometrics of the project road. Alignment has been proposed keeping in view of existing alignment deficiencies and available Right of Way and traffic diversion at the time of construction. At first bridge near Indian/Myanmar border, Alignment Proposed on right side of existing steel bridge considering direct connectivity to Proposed

Structure Proposal
Out of 71 existing steel bridges two minor bridges are under construction. Remaining 69 steel bridges which are structurally distressed will be reconstructed. All existing RCC bridges (falling on steel bridge approaches) which are sound in condition but narrower than 7.50 m wide carriageway will be widened and remaining RCC bridges which are in sound condition with 7.50m wide carriageway will be retained.
All steel bridge will be replaced with new Bridges as per circular {Width of bridges on 2 lane National Highways (with or without footpath)} of “Ministry of Road Transport and Highway”.
The total width of deck is 12.90m with clear carriageway width of 10.50m, crash barrier of 0.45m and raised kerb of 0.75m on each side in bridge for bridges in plain / rolling terrain . The total width of deck is 10.00m with clear carriageway width of 7.50m, crash barrier of 0.45m and 0.80m raised safety kerb on each side in bridge for bridges in hilly section.
For Bridge no. 1, total width of deck is 14.80m with clear carriageway width of 10.50m, crash barrier of 0.45m, railing of 0.20m and footpath of 1.50m on each side in bridge.
Based on geotechnical, simplicity of construction and execution, it is proposed to provide
PCC/PSC Girders Superstructures with open/pile foundations. Depends on the waterway discharge
and existing ground longitudinal profile the number of spans and span lengths has been decided.

There are total 59 numbers of culverts consisting of 44 Slab, 6 Arch and 9 Hume Pipe culverts. The condition of most of these CD structures are fair to good.
Geometric Design
Geometric design involves the design of the visible elements such as horizontal alignment, vertical alignment and the cross-section of the project road. The design is governed by the design speed fixed up taking into account site conditions including the terrain in which the project road traverses.
The project road traverses through plain/rolling and hilly terrain and a design speed of 100/80 kmph & 50/40kmph has been provided. However the minimum values have been applied only where serious restrictions are placed by technical or economic considerations. At few locations design speed has been reduced due to unavoidable circumstances. General effort has been made to exceed the design speed on safer side.
The entire geometric design has been based on the ground modelling by highway design software MOSS/MX Road.
Pavement Design
Based on the traffic projections and the Vehicle Damage Factor (VDF) of various types of commercial vehicles, Cumulative standard Axles (CSA) during the period of design life have been computed for the homogeneous sections.

1. There will be no loss of bio-diversity as no rare plant or animal species are going to be affected by the present project.
2. No Sanctuary or National Park is located within 10 km radius of the bridges.
3. No historical monuments are located near the bridges.
4. The most important factors, which need continuous attention and assessment during the construction phase, are the ambient air quality, the water quality and the noise level. The ambient air quality of the study area is good. The quality of the ground water is good for drinking as well as other daily use purpose. Noise levels in the area, particularly at crossing points and in the urban settlement, exceed the limits.
5. The proposed alignment of the bridges and their approaches would be such that it has minimum impact on physical and social environment. Approximately 158 numbers of trees may be cut down due to the proposed approach roads connecting bridges. No forest area will be diverted.

project road is in the vicinity of Chindwin River. As a result a number of water courses/ streams
have been formed across the proposed alignment. The major streams crossing the project road
areLakchao, Nanpalong, Lalim, Nie-Ell-Kiaiz, Tuivang, Kanmagyi, Kannan and some local
streams.
3.5 CLIMATE
Myanmar has three main seasons, hot season, rainy season and cold season. Hot season is from
March to May, rainy season is from June to October and cold season is from November to
February. The tropical monsoon is usually cloudy, rainy, hot, humid summers and less cloudy,
scant rainfall, mild temperatures, lower humidity during winter.
April and May are the hottest months in the project area, while the extreme temperature varies but
mean maximum temperature works out to be 31º C in Mawlik Town. During the rainy season, from
May to September, climateremains very humid. During winter season and particularly rainy season,
thick, low lying clouds reduce visibility, impede movement and hold up work. Depending on the
variation in temperatures and general weather conditions, three different types of seasons are
observed in Project Influence Area (PIA):
Winter: Starts from November and lasts till February. The temperature is comparatively lower
(11° C – 28° C), but not too low to make human habitation difficult. The season
receives very little rainfall.
Spring: Season begins from March and lasts till first half of May and merges with rainy
season. The temperature rises up to a range of 16° C to 35° C being aggravated by
rainless days.
Rain: This is the longest season; hold out for nearly sixmonths from second mid of May till
late October. Rainfall is very heavy from June toSeptember, and maximum rainfall
observed in the month of September.
Elevation and distance from the sea affect temperature as well. Although Myanmargenerally is a
tropical country, temperatures are not uniformly high throughout the year. The daily temperature
range is greater than that in nearly all other parts of Southeast Asia, but no locality has a continental
type of climate (i.e., one characterized by large seasonal differences in average temperature).
Mandalay, in the centre of the dry zone, has some of the greatest daily temperature ranges, which
span about 12 °C annually. In broader perspective, however, average daily temperatures show little
variation, ranging from 26 °C to 28 °C between Sittwe (Akyab) in the Rakhine region, Yangon near
the coast, and Mandalay in the northern part of the central basin. At Lashio, on the Shan Plateau,
the average daily temperature is somewhat cooler, around 22 °C.
3.6 SOCIO ECONOMIC PROFILE
Area and Population
The total area of Myanmar is 678,500 sq km where 657,740 sq km occupies the land and 20,760 sq
km occupies the water. The bordering countries are Bangladesh 193 km, China 2,185 km, India
1,463 km, Laos 235 km, and Thailand 1,800 km. The central lowlands ringed by steep, rugged

Myanmar is made up of 135 national races, of which the main national races are Kachin, Kayah,
Kayin, Chin, Bamar, Mon, Rakhine and Shan. Population is estimated to be over 60
million.Population growth rate shown in Table3.2.Statewise population for the last three years has
shown in Table 3.3.The nationality is Myanmar. There are more than 100 ethnic groups in
Myanmar. Some of the Ethnic groups are listed as Akha, Palaung, Padaung, Naga, Taron, Eng and
many more near extinct tribes. The religions are Buddhist, Christian and Muslim. The major
language is Myanmar, but minority ethnic groups have their own languages. English is widely
spoken and understood.
The majority of Myanmar’s population is rural, with the density of settlement in each region related
to agricultural production, particularly of rice. Thus, the most populous regions are the Irrawaddy
delta and the dry zone, and the highest densities are found in the upper delta, between Yangon and
Hinthada (Henzada). Settlement in the Sittang delta, the sedimented hinterland of Sittwe, and the
regions of both sides of the lower ChindwinRiver is moderately dense. The Rakhine region (except
the Sittwe area), the west bank of the Irrawaddy at the base of the Rakhine Mountains, Tenasserim,
and the less accessible parts of the western and northern mountains and the Shan Plateau are
sparsely inhabited. Although city populations have been growing, the pace of urbanization has not
been as rapid in Myanmar as it has been in most other countries of Southeast Asia.
The population of Myanmar remains fairly youthful, with roughly one-fourth of the people under
age 15. However, the proportion of young people has been decreasing steadily since the late 20th
century, as the birth rate has dropped from notablyabove to significantly below the world average.
Life expectancy, on the contrary, has been on the rise, with most men and women living into their
60s.

Economy
Myanmar’s economy, based on the kyat (the national currency), is one of the least developed of the
region and is basically agricultural. Much of the population is engaged directly in agricultural
pursuits. Of those who are employed in other sectors of the economy, many are indirectly involved
in agriculture through such activities as transporting, processing, marketing, and exporting
agricultural goods.
Nearly half of Myanmar’s economic output—notably all large industrial enterprises, the banking
system, insurance, foreign trade, domestic wholesale trade, and nearly all the retail trade—was
nationalized in 1962–63. Agriculture and fishing were left in the private sector. In 1975–76,
however, the government reorganized nationalized corporations on a more commercial basis and
instituted a bonus system for workers. The overall economic objectives of self-sufficiency and the
exclusion of foreign investment also were revised. Foreign investment was permitted to resume in
1973, although only with the government. Following a military coup in 1988, both foreign and
indigenous private enterprise was encouraged.
Myanmar also has an extensive informal economy. Considerable quantities of consumer goods are
smuggled into the country, and teak and gems are exported both legally and illegally. In addition,
northern Myanmar is one of the largest producers of opium in the world.
Myanmar had undergone various economic systems in her long historical past. Beginning with the
British colonial era, the free market system with the laissez-faire and free trade doctrine had been
the guiding philosophy and policy of the British colonial administration for a century. The national
governments since independence in 1948 till early 1962,practised a mixed-economy model,
allowing the market forces to play a leading role in the development process. Then for 26 years,
since 1962, socialism with a centrally planned economy was adopted. Finally, following the
political disturbances in August 1988, the State Peace and Development Council (SPDC) assumed
power in September 1988, abolishing socialist system and instituting instead market-oriented
economic system. Since November 1988, the SPDC undertook a number of economic stabilization
and reform measures toredress the worsening economic situation of the country. Accordingly, the

economy began to recover slightly during 1989-90 to 1991-92, after registering negative growth
rates during the past three consecutive years. Accordingly the economy have achieved high growth
in GDP with annual average growth rate of 7.5% during the first four year plan, 1992-93 to 1995-96
and during the second five year plan, 1996-97 to 2000-2001, an annual average growth rate of 8.5%
was achieved. The GDP growth rate of 2001-2002, the first year of the current five year plan
revealed 11.8%. The GDP Growth rate for year 2011-2012 was 6.30%. GDP growth rate for

Agriculture, forestry, and fishing
Agriculture, forestry, and fishing together constitute the largest contributor to Myanmar’s economy.
About half of all agricultural land in Myanmar is devoted to rice, and to increase production the
government has promoted multiple cropping (sequential cultivation of two or more crops on a
single piece of land in a single year), a system that is easily supported by the country’s climate. As
a whole, the sector accounts for nearly one-half of the country’s gross domestic product (GDP) and
employs about two-thirds of the labour force.
Myanmar may be divided into three agricultural regions: the delta, where cultivation of rice in
flooded paddies predominates; the largely irrigated dry zone, an area primarily of rice production
but where a wide variety of other crops also are raised; and the hill and plateau regions, where
forestry and cultivation of rice and other crops through shifting agriculture are most important.
Although the dry zone was Myanmar’s most important agricultural region in the past, the rice
production of the Irrawaddy River delta now provides much of thecountry’s exportearnings and the
staple diet of the country’s people. The delta’s traditional agriculture consisted primarily of rice in
normal years, with the substitution of millet in drier years when there was insufficient moisture for
rice; both grains yielded good returns on the alluvial soils.

Crops raised in the dry zone, in addition to rice, include sugarcane, fruits (such as plantains),
legumes, peanuts (groundnuts), corn (maize), onions, sesame, rubber, and allspice. To cultivate
much of this land successfully, however, irrigation is required. The earliest known irrigation works
were constructed in the 1st century and greatly improved in the 11th century; though their
maintenance lapsed somewhat after the fall of the monarchy in the late 19th century, many are still
in active service. As in the delta, the arrival of the British in the dry zone led to increased
commercial and public-works activities. British authorities repaired and extended parts of these
ancient systems during the early 20th century. Most of Myanmar’s irrigated land is in the dry zone,
and almost all of it is planted in rice. The portions of the dry zone that are not irrigated are utilized
for the production of crops that are less sensitive to the seasonality or irregularity of rainfall than
rice. In addition to the crops mentioned above, cotton and millet are cultivated, although neither is
of considerable significance. Cattle also are raised there.
The third agricultural zone, the hill and plateau country, occupies perhaps two-thirds of the area of
Myanmar. This land has less economic significance than the other two zones; it is the home of
many of the country’s non-Burmanethnic groups, most of whom are engaged in shifting cultivation.
More-sedentary modes of agriculture also exist, however, and have been imposed with the advance
of agricultural technology, increased population, and central planning. Outside the forest areas of
these highlands, the principal crops raised are rice, yams, and millet, and large numbers of pigs and
poultry are kept. Bullocks and buffalo are used as draft animals, and goats, pigs, and poultry are
raised for food in all parts of the country.
The second most important element in the diet, after rice, is fish—fresh or in the form of ngapi, a
sort of nutritional paste that is prepared in a variety of ways and eaten as a condiment. Much
private, noncommercial fishing is provided, however, in virtually every type of permanent,
seasonal, or artificial body of inland water of any size. Nonindigenous fish, including the European
carp and the tilapia (originally brought from Thailand), have become the focus of a growing
aquaculture industry.
Forestry has been particularly important as a source of foreign exchange. Myanmar is estimated to
have the bulk of the world’s exploitable teak supplies. Teak is found in the tropical-deciduous
forests of the hills. Although the forests are owned and regulated by the state, concern has been
raised about indiscriminate and illegal logging.
Resources and Power
Myanmar is rich in minerals, including metal ores, petroleum, and natural gas, and also has
significant deposits of precious and semiprecious stones. Although production has been increasing
from last few decades still mining sector accounts for small portion of country’s GDP having small
share of workforce.
Large-scale exploitation of Myanmar’s mineral deposits began in the mid-1970s. Deposits of silver,
lead, zinc, and gold are concentrated in the northern Shan Plateau, tin and tungsten in the
Tenasserim region, and barite around the town of Maymyo in the central basin. Copper mining at
the town of Monywa began in the early 1980s and has been growing, despite intermittent setbacks
caused by shortages of fuel and supplies as well as by economic sanctions imposed by foreign
governments.

Rubies and sapphires have been mined in the northern Shan Plateau since precolonial times. Jade is
mined in the northern mountains. The country also produces smaller quantities of spinels,
diamonds, and other gemstones.When Myanmar was colonized by the British in the late 19th
century, the extraction of petroleum from the country’s central region already was an established
local practice. The industry was expanded by the British and, since the mid-20th century, by the
government of independent Myanmar. Although exploration for onshore petroleum resources since
independence has not proved particularly fruitful, exploration for natural gas has been especially
productive. Exploitation of onshore gas fields began in the 1970s, and in the 1990s extensive gas
fields were opened offshore—especially in the Gulf of Martaban—and a pipeline was constructed
to serve Thailand. There are oil refineries at Chauk, Syriam, Mann, and other locations.
Myanmar also has major deposits of coal, and production rose sharply in the early 21st century.
Coal is mined primarily in the upper Irrawaddy and Chindwin valleys.
The demand for electricity chronically has outstripped capacity. Although much of the country’s
energy is drawn from fossil fuels, hydroelectricity accounts for a significant and rapidly expanding
segment of Myanmar’s total power supply. The government has built several hydroelectric power
plants, including those on the BaluRiver (a tributary of the Salween), at Taikkyi near the city of
Bago (Pegu), in the northern Rakhine region, and near Mandalay.
Manufacturing
There was little industrialization in Myanmar until the mid-20th century, when a limited program
was initiated after the country achieved independence. Yangon, Myingyan (in the dry zone), and the
Rakhine area were selected to become the new industrial centers. Although the manufacturing
sector has expanded, it has not grown as rapidly in Myanmar as it has in other countries of the
region.
A major enterprise in Myanmar is tobacco production, consisting of government-owned factories,
which manufacture cigarettes, and cottage industries, which produce cheroots (a type of small
cigar). Other important industries include steel processing, the manufacture of nonelectrical
machinery and transportation equipment, and cement production. Textile factories have been
established in Yangon, Myingyan, and other cities, but growth of the industry has been hindered
since the late 20th century by intermittent sanctions by foreign governments. Myanmar also
produces lumber, paper, processed foods (mainly rice), and some pharmaceuticals. Cottage
industries are encouraged by subsidies.
Trade
The government’s decision in the early 1960s to limit foreign trade reversed the export orientation
of the British colonial period. However, the subsequent relaxation of trade restrictions, notably the
legalization of trade with China and Thailand in the late 20th century, allowed trade again to
become a significant component of the national economy. Natural gas is Myanmar’s primary
export, followed by pulses (mostly dried beans), teak, and minerals and gems. Its principal imports
include machinery and equipment, industrial raw materials, and consumer goods. Owing largely to
the sanctions imposed by the United States and members of the European Union since the end of

MEA 3-9
the 20th century, Myanmar’s Asian neighbours—including Thailand, Singapore, China, Hong
Kong, India, and Japan—have become its chief trading partners.
Transportation
The country’s trade in rice is dependent on water transport. The Irrawaddy River is the backbone of
Myanmar’s transportation system. The Irrawaddy is navigable year-round up to Bhamo and to
Myitkyina during the dry season, when there are no rapids. The Chindwin is navigable for some
500 miles (800 km) from its confluence with the Irrawaddy below Mandalay. The many streams of
the Irrawaddy delta are navigable, and there is a system of connecting canals. The Sittang, in spite
of its silt, is usable by smaller boats, but the Salween, because of its rapids, is navigable for less
than 100 miles (160 km) from the sea. Small steamers and country boats also serve the coasts of the
Rakhine and Tenasserim regions.
The first railway line, running from Yangon to Pyay (Prome) and built in 1877, followed the
Irrawaddy valley. The line was not extended to Mandalay; instead, after 1886 a new railway from
Yangon up the Sittang valley was constructed, meeting the Irrawaddy at Mandalay. From Mandalay
it crossed the river and, avoiding the Irrawaddy valley, went up the Mu River valley to connect with
the Irrawaddy again at Myitkyina. A short branchline now connects Naba to Katha on the
Irrawaddy below Bhamo.
The Yangon-Mandalay-Myitkyina railway is the main artery, and from it there are branchlines
connecting the northern and central Shan Plateau with the Irrawaddy. Other branches run from
Pyinmana across the Bago Mountains to Kyaukpadaung and from Bago to Mawlamyine to Ye. The
Pyay-Yangon railway has a branchline crossing the apex of the delta to Hinthada and Pathein
(Bassein).
The road system, until independence, was confined to the Irrawaddy and Sittang valleys,
duplicating the railway route. A road goes from Pyay along the Irrawaddy to the oil fields, and
many roads extend into the rural areas. These rural roads, however, are often impassable during the
wet season. There were originally three international roads in use during World War II: the Burma
Road from Lashio to Kunming in China; the Stilwell, or Ledo, Road between Myitkyina and Ledo
in India; and the road between Kengtung, in the southeastern Shan Plateau, and northern Thailand.
These roads subsequently became neglected but more recently were rebuilt and extended.
The state-run Myanmar Airways International runs frequent domestic flights between Yangon and
other cities; it also has international service from Yangon to several major Southeast Asian cities.
There are also small privately owned airlines that offer domestic and very limited international
service. International airports are located in Yangon and Mandalay.
Yangon, as the terminus of road, rail, and river-transport systems, is the country’s major port, with
up-to-date equipment and facilities. Pathein, Mawlamyine, and Sittwe are also important ports.
Sagaing Region
Sagaing Region is located in the north-west of Myanmar between 21o30 'N latitudes and 94o97'E
longitudes. It is bordered by India’sNagaland and Manipur States to the north, Kachin State, Shan
State, and Mandala Region to the east, Mandalay Region and Magway Region to the south, with

the Ayeyarwady River forming a greater part of its eastern and also southern boundary, and Chin
State and India to the west. The region has an area of 93,527 km². The capital is Sagaing.
Area & population
Sagaing Region is inhabited by different Myanmars, Kachins, Chins, Nagas, and Shansin 34
Townships and 198 Wards and Villages. It has a population of about 63, 92,000. Main agricultural
crops are paddy, wheat and maize althoughsesame, peanut, pulses, cotton and tobacco are also
grown. The Region is the top producer of wheat in the whole country and also has the largest
acreage of sunflower. Cultivable acreage has increased as the State has built irrigation works,
introduced terrace cultivation, distributedpedigree seeds and insecticides and provided tractor
ploughing.
Resources
The 12734 square miles of Forest Reserves in Sagaing region as timber extraction work is the
Region's principal industry as valuable teak forests are widespread in the Region. Forestry is
important in the wetter upper regions along the Chindwin River, with teak and other hardwoods
extracted. A copper extracted from huge copper deposits in Sabe hill and Kyesin hill in Salingyi
Township of Sagaing Region. Important minerals of the Division are gold mined at Kyaukpahto
region, Kawlin Township, coal mined at Kalewa (Thitchauk) region and Monywa. A small amount
of oil is found at Pantha and Inndaw regions at Chindwin River valley. Salt is produced in Wetlet
and Sagaing Township.
Ecotourism
In the Sagaing Region, across the Ayeyarwaddy River which is largest river in the country are the
MingunPahtodawgyi and the Largest Ringing bell known as Mingun Bell. There is Alaung-dawKa-
tha-pa National Park which is home to large populations of wild elephants and other rare wildlife
species. It is more of a religious site than a national park, drawing at least 30,000 pilgrims a year
paying homage to wild pigs and tigers.
