The existing Lees Avenue bridge over 417 will be removed this weekend. To safely remove the bridge, Highway 417 will be closed in both directions, starting 6 p.m., Saturday, June 21 until 11:00 a.m., Sunday, June 22 at which time a single lane of traffic will be reinstated in both directions. All lanes on Highway 417, in both directions, will be reopened by Monday, June 23, at 5 a.m.
During the full closure of Highway 417, traffic will be detoured as follows:
– Eastbound traffic will be required to exit Highway 417 no further east than the Metcalfe Street and will be detoured via Isabella, Hawthorne, Main and Riverside Drive where they may again access Highway 417 to continue travelling eastbound
– Westbound traffic will be required to exit Highway 417 no further west than Vanier Parkway and will be detoured via Riverside Drive and Bronson Avenue where they may again access Highway 417 to continue travelling westbound.
The city has also advised that in order to ensure traffic flows along the detour route this weekend, temporary NO STOPPING signs will be installed where parking, loading, or stopping is usually permitted: on south side of Hawthorne Avenue from Colonel By Drive to Main Street; and on west side of Main Street from Hawthorne Avenue to Riverside Drive.
