Motorists are being advised to expect delays as the city closes Highway 417 overnight from Bronson to Carling. 

The closure is part of the Herman Avenue pedestrian bridge replacement. Crews will begin the demolition just after six Saturday and are expected to be able to re-open the highway starting around 11:00 a.m. Sunday morning. 

During the work, the following eastbound on-ramps will be closed: Carling, Parkdale and Maitland. The following westbound on-ramps will be closed: Catherine, Rochester, Parkdale, Lyon and O’Connor.

"It's an end of life cycle and requries to be replaced," said Chris Brinkman with the city of Ottawa. 'We expect delays but the reason we schedule this kind of work on the weekend and overnight is to reduce congestion."
