Calgary’s Mission Bridge will be closed to motorists for several months while municipal crews complete rehabilitation work.

After peak hours on Friday, November 1, the bridge, located on Fourth Street SW, will be closed to allow crews to begin work on vehicle travel lanes. The closure is expected to last approximately six months.

Northbound and southbound detours will be available for drivers.

Along with “critical repair work,” city crews are also working to add multi-use pathways on each side of the bridge and improve lighting.

Some sidewalks on the bridge will have a reduced width but will remain open to pedestrians, wheelchairs and cyclists.

The bridge is expected to reopen to vehicular traffic in both directions in the spring, with the project completed by the end of 2025.

The city reminds commuters to allow extra time and use alternate routes or modes of transportation when possible.

The project began in May and exterior work on the structure is now complete.

“We have made good progress over the summer on the required repairs to the exterior of the bridge and are ready to begin work on the interior,” said Max Lacroix, project manager and senior structural engineer with the City , in a press release.

“Understandably, the shutdown is a difficult time for people living, working or playing in the Mission District. However, this allows us to best manage repairs to the bridge so that it can last another 35 years until further work is required.

The project will cost the city $17.8 million. One of Calgary’s oldest bridges, the Mission Bridge was built in 1915 and last upgraded in 1987.
