The Durham Street Bridge in Walkerton will be closed overnight Thursday as crews continue to complete rehabilitation work.
Bruce County has issued a notice that the bridge will close to all traffic starting at 10 p.m. on June 11.
It should reopen before the next morning's commute, around 4 a.m. on Friday June 12.
A map of detours available during the roughly six hour closure can be found here.
Once the full closure ends, the bridge will return to alternating traffic with temporary traffic lights.
The County said it anticipates the rehabilitation work will be fully completed in July.
