Commuters travelling across the Burlington Canal Lift Bridge can expect delays this week.
Public Services and Procurement Canada said maintenance work will lead to lane closures from 9 a.m. to 3 p.m. today, tomorrow and July 4.
Two lanes will remain open with on-site flag persons redirecting traffic.
The bridge will also stay open to cyclists and pedestrians, and marine traffic should not be affected during the lane closures.
The schedule may change depending on weather conditions.
