CROSSTOWN

CONSTRUCTION UPDATE

FALL 2014

Welcome to the Open House

Eglinton Crosstown LRT

• Project

– $5.4 B (2010$), funded by the Province of Ontario

– 19 kilometres east-west LRT from Kennedy to

Jane/Black Creek, including 10 kilometers of

tunnel

– Connections to Yonge-University-Spadina

Subway, Scarborough RT and GO Stouffville

– Up to 26 stations

Tunnelling Works 2014-2016

Construction Timeline

• At future station locations underground structures (emergency exits, cross passages) utility relocation and headwall installation are expected to last approximately six to eight months on average

• When the TBMs reach Eglinton West Station, they will be extracted using a shaft located just west of Allen Road.

• The TBMs will be refurbished and re-launched just east of Allen Road, for the second phase of tunnelling to Yonge Street.

• Tunnelling activities to Yonge are expected to be completed by December 2016

• Following the completion of tunnelling works, the sites will be turned over to the Metrolinx station contractor in two phases; west of Allen Road (2014) Allen Road to Yonge (2015)

• Station construction expected to begin Spring/Summer 2015

Tunnel Drive Works 2014

• Headwalls are temporary support walls for future

excavation of the LRT stations.

• Made of concrete and installed to the depth of the

future track level

• Jet Grout method of installation will be used on

headwalls east of Allen Road

• Machinery including drill rigs, grout tanks,

excavators and other equipment

Construction

Tunnel Boring Machines

• The construction of new tunnels under Eglinton Avenue is done by tunnel boring machines (TBMs)

• Each TBM moves forward by pushing off against concrete segments

• The operator advances the machine as soil is removed from the TBM face through a conveyor system

• The launch pit remains active for removal of muck/spoils

Launch Shaft Tunnel Boring Machine

Tunnel Drive Works Current Status

• In 2013 the majority of the tunnel drive and associated works took place between Black Creek Drive and the vicinity of Allen Road

• In 2014 work continues east of Allen Road

• Crews continue the construction of headwalls and utility relocation at future station sites along Eglinton Avenue West

• TBM 1 is well underway with tunnelling; TBM 1 is now located west of Oakwood Avenue

• TBM 2, a twin machine is following closely behind

Grout Plant for Headwall Construction

Why a grout plant at Peveril Hill North?

• Headwalls for Bathurst required

• Peveril Hill North adjacent to work site

• There will be no access to/from Eglinton Avenue West at Peveril Hill North

• Peveril Hill North between Dewbourne Avenue and Eglinton Avenue will be local access only

• Allows efficient use of space

• Peveril Hill North preferred because of reduced footprint on Eglinton Avenue

The site will occupy City of Toronto

roadway

The plant will be located on Peveril

Hill N requiring closure of the

street at Eglinton

A fence will enclose the site

The plant will service headwall

construction for Bathurst Station

on the north and south sides of the

street

The plant is expected to be in

place for approximately 6 months

Grout Plant at Peveril Hill N

Jet Grout

Advantages of jet grout

technique for headwall

installation:

Reduce requirement for

extensive utility relocation

Overall construction time

savings

Timeline for Bathurst Headwall Works

With appropriate permissions in place Metrolinx’ contractor will:

• Begin to set up the grout plant at Peveril Hill N.

• Install fencing and secure the perimeter

• Install grout lines in the roadway

• Test works

• Begin Bathurst headwall construction works

• Scheduled to commence in September 2014

• 6 months anticipated

Timeline for Avenue Headwall Works

With appropriate permissions in place Metrolinx’

contractor will:

• Begin to set up the grout plant at Highbourne Avenue

• Install fencing and secure the perimeter

• Install grout lines in the roadway

• Test works

• Begin Avenue Road headwalls in Fall 2014

• 6 months anticipated at each wall

Utility Relocations

• Depending on site conditions: gas, hydro, water mains, sewers, lighting and telephone and cable lines may be relocated to allow for construction

• In the vicinity of the launch and extraction shafts Metrolinx is co-ordinating with Bell, Enbridge, Toronto Water, Toronto Hydro and Cogeco regarding required relocations

• In most cases utility relocations will be undertaken by Metrolinx contractor

• Enbridge will coordinate works with Metrolinx

Bathurst Headwall Locations

Avenue Headwall Locations

Approach to Traffic Management

• Maintain a minimum of one lane eastbound and westbound on Eglinton in construction work zones

• Buses and general traffic will share this lane

• Additional lanes will be provided if space allows

• Metrolinx will work with City of Toronto Transportation, local elected officials and neighbours to monitor local traffic

• Signal timing may be modified and turning restrictions may be added or relaxed

Emergency Exit Buildings and Cross

Passages

• Cross passage and emergency exit construction will take place between late 2014 through late 2016

Transit Services during Tunnel

Construction

• Both eastbound and westbound TTC stops in the

affected area may be shifted and relocated for the

safety of transit riders

• Watch for TTC posted signs indicating the adjusted

stop locations

• Metrolinx coordinates with TTC for service

adjustments required due to construction. TTC is

responsible for bus detours and rerouting

Cross Passages

• A cross passage is a tunnel connecting the eastbound and westbound tunnels for maintenance and/or emergency purposes

• Crews will be building cross passages before and after the tunnels are complete

• Some construction works will be visible at street level while other works take place underground

Pedestrians

• In the construction zone for temporary sidewalks or

existing sidewalks the goal is to maintain 1.5 metre

sidewalk widths wherever possible

• Access to properties from sidewalks should be

maintained

• Some sections of sidewalk may be closed and

crossings will be available at traffic signals

• Please take care when travelling near construction.

Watch for additional signage directing pedestrians

Next Steps

• Community Relations will outreach to businesses,

specific condos and apartment buildings to raise

awareness of the site and planned works

• Co-ordination with TTC will continue to ensure

continued bus service

• Co-ordination with local emergency services also

continues to ensure service levels
