We received the following yesterday from the City.
Construction on the Harmer Avenue Pedestrian/Cycling Bridge Replacement is progressing very well. Construction started in 2018 and is scheduled for completion by summer 2020.
The next phase of the project will include the bridge truss installation over Highway 417 and will require a temporary closure of the Highway 417 between Carling/Kirkwood Avenues and Bronson Avenue.
The highway will be closed in both directions on Saturday, October 19 until Sunday, October 20. Lane reductions and ramp closures are scheduled to start at 5 pm followed by the full highway closure expected at 6 pm. Closures are expected to be removed on Sunday at 11 am. Significant traffic impacts are expected during this time. This same approach was used successfully in July 2018 for removal of the structure.
Eastbound on-ramps to the highway will be closed at Maitland, Carling and Parkdale. Westbound on-ramps to the highway will be closed at O’Connor, Lyon, Bronson, Rochester, and Parkdale. All highway lanes except one in each direction and all ramps are scheduled to be open by 11am on Sunday October 20, 2019.
There will be a signed detour as follows:
As this closure will have traffic impacts, delays are expected. Residents are encouraged to avoid the area during the closure and take alternative routes and/or modes of transportation.
