Traffic and transit changes due to the Chaudière Bridge closure

April 28, 2019
Announcements and Events

The Chaudière Bridge has been closed by Public Services and Procurement Canada to all vehicles and pedestrians as of 6 am on Sunday, April 28. Commissionaires will be stationed at both ends of the closure to redirect all vehicles and pedestrians to the Portage Bridge. This closure is a result of forecasted high water levels and flows and will remain in place until the water recedes to a level where the bridge is safe for inspections and use.

Beginning Monday, April 29, traffic is expected to be heavy on Albert Street with back-ups occurring on Booth Street northbound to Albert Street. The public travelling in the area should prepare for delays and plan in advance. Ottawa Police Services will be providing support to move motorists and transit through the intersection.
