Prepare for traffic impacts on Danforth Avenue as crews prepare for Lakeshore East Rail Corridor bridge work

Work on the Lakeshore East Rail Corridor continues to ramp up, and it means there will be traffic impacts on Toronto’s Danforth Avenue. Traffic will be reduced to single lanes in both directions to give crews enough elbow room to widen the Danforth bridge. The bridge construction is part of GO Expansion, bringing more frequent service to the Lakeshore East line.

Editor’s note (July 22, 2021) – Metrolinx reports this work has been delayed and is now expected to take place in August, 2021.

More construction is happening on the Lakeshore East Rail Corridor, which will impact traffic on Toronto’s Danforth Avenue.

The upcoming work is part of the massive GO Expansion, bringing communities one step closer to faster and more frequent GO train service on the Lakeshore East line.

The traffic impacts are necessary to expand the Danforth bridge, which is part of the Lakeshore East Corridor. The work being done now will accommodate a future fourth track to deliver faster, more frequent GO rail service.

Starting July 26, (Update – This work has been delayed until August, 2021) Danforth Avenue will be reduced to single lane conditions in both directions while Metrolinx widens the existing pier of the rail overpass between Scotia Avenue and Eastwood Avenue.

This specific work (stage one) will be ongoing until mid-September.

One lane for vehicles in each direction will be maintained as well as sidewalks on either side of Danforth Avenue will remain open.

TTC bus stop, servicing bus route 20, located at Medford and Danforth Avenue will be relocated 50 metres west on Danforth Avenue.

The traffic reconfiguration will also allow crews set up a safe working perimeter around the centre of the road, where there will be no public access. Delineators will be in place, and directional signage will be installed. Other stages of work on the bridge will follow, and residents can expect to see construction activity until spring 2022. Metrolinx will continue to share advance notice and details of any traffic impacts.

Residents can expect to see construction vehicles and equipment within the rail corridor, on Danforth Avenue, and in the surrounding areas, including pile driving equipment, dozer, crane, excavator, concrete trucks, and dump trucks. Due to the nature of this work, noise, vibration dust and site lighting can be anticipated.

Metrolinx understands the inconvenience of the closure, and crews will be working hard to get the job done safely and as quickly as possible. Work will occur five days a week (Monday to Friday) between the hours of 7a.m. and 5p.m.

Those travelling in the area should plan and incorporate extra time for travel.

Work on the Danforth bridge is part of the Lakeshore East Rail Corridor Expansion project in Toronto, which includes grading, retaining walls, constructing a new culvert and bridge widening to accommodate a future fourth track. By building on what is there today, Metrolinx can improve infrastructure that will deliver faster, two-way, all-day, 15-minute service on core segments of the network.
