The Burgoyne Bridge is shutting down next week.
It's a full closure of the bridge beginning Monday and it won't reopen until Saturday.
Traffic will be detoured via Regional Road 81 (St Paul Street), Louth Street, Regional Road 77 (Fourth Avenue), and Ontario Street during the closures.
Pedestrian access will be maintained.
The closure is required so crews can complete installation of the cable supports for the structural arch on the bridge.
