the governments that typically develop and maintain
them.The Pan-American Highway is considered the
longest highway in the world. It stretches from Alaska
to Argentina and Chile and covers 48,000 miles. Someparts are barely passable during wet season, as it
crosses multiple different countries and climates.

The state has the power to control and
regulate the use of public highways, provided
its regulations do not constitute an
unreasonable interference with the right of
travel.
The state may determine the character of
motor vehicles that use its highways and mayproperly exclude vehicles weighing in excess.
A reasonable tax may be imposed on vehicles
based on their excess weight in order tocompensate the state for the additional costs
of maintaining the highway as a result of the
severe wear and tear placed on the road by
such vehicles.

Reducing travel times relative to city or townstreets, modern highways with limited access and
grade separation create increased opportunities for
people to travel for business, trade or pleasure.Also they provide trade routes for goods.
Modern highways reduce commute and other
travel time by additional road capacity.Positive externalities of transport networks may
also include the ability to provide emergency
services.

High-occupancy vehicle lanes are being added
to some newer/reconstructed highways in NorthAmerica and other countries around the world
to encourage carpooling and mass-transit.
These lanes help in reducing traffic
congestion by promoting the use of carpooling .
However, they tend to require dedicated
lanes on a highway, which makes them difficult
to construct in dense urban areas where theyare the most effective.

Negative externalities are wide-ranging and may
include local air pollution, noise pollution, lightpollution, safety hazards.etc.
Roadway noise increases with operating speed so
major highways generate more noise than arterialstreets. Therefore, considerable noise health
effects are expected from highway systems.
New highways can also cause habitat
fragmentation, encourage urban sprawl and allow
human intrusion into previously untouched areas,
as well as increasing congestion, by increasing the
number of intersections.
