Chaplin Station Headwall Construction for Twin Tunnels - Stage 2

May 21, 2014

The Eglinton Crosstown is a 19-kilometre light rail transit (LRT) line that will run along Eglinton Avenue through the heart of Toronto, with an underground central section. The line will connect Mount Dennis in the west to Kennedy Road in the east, and the new service will be up to 60% faster than the bus service today.

What we are building

What: Crews will be building headwalls for the future Chaplin Station and cross-passages for the future maintenance of the tunnel. Headwalls are underground support walls located at the east and west ends of the station location. Following the site preparation, crews will be installing these underground station headwalls in advance of the twin tunnel construction.
Why: Station headwalls create the frame for future underground stations, and are required to be in place prior to the arrival of tunnel boring machines at each of the station locations along the Eglinton Crosstown route.  Construction of the headwalls requires a grout plant to be established nearby to pump a form of concrete, otherwise known as “grout”, to the station headwall location. 

Where: The work zone will extend from approximately east of Spadina Road to Heddington Avenue along Eglinton Avenue West. The work zone will be separated from the right-of-way with traffic cones and concrete barriers and/or fencing.  Various traffic control measures and construction zones will occupy the Eglinton Avenue and Chaplin Crescent intersection and change and shift over the coming months for the construction of two station headwalls.

When: A new traffic pattern for the construction of headwalls will start as early as the last week of May 2014. Construction is expected to continue to late fall of 2014. Following this new stage of traffic, there will be additional short term roaming lane restrictions for the installation of grout lines on Eglinton Avenue, east and west of Chaplin Crescent.  Timelines may be rescheduled or adjusted due to weather conditions and unforeseen circumstances.
