The Don Valley Parkway is closed this weekend for spring maintenance.
About 200 city workers are completing a range of maintenance activities, said Kyp Perikleous, Director of Transportation Services.
Some of the work includes resurfacing 14.3 lane kilometres of roadway, cleaning and repairing 600 catch basins, inspecting and repairing 30 overhead signs, and shoulder regrading to restore drainage.
The city says that it will implement timing changes on traffic signals to expedite the flow of traffic on nearby routes during the closure.
The DVP is shut down between the Gardiner Expressway and Highway 401 until 5 a.m. on Monday.
