Hwy. 417 is closed until Monday for Preston Street bridge replacement. Here's what you need to know

Motorists will have to sit through one more day of traffic delays in Ottawa on Sunday, as Highway 417 remains closed for the replacement of the Preston Street overpass.

Hwy. 417 is closed eastbound and westbound between Carling Avenue and Metcalfe Street for the replacement of the aging Preston Street bridge. The highway is scheduled to reopen at 6 a.m. Monday.

On Sunday morning, the new overpass was in place and construction crews worked on repaving the highway and the new bridge before it reopens to traffic.

Preston Street is also closed between St. Anthony Street and Young Street until Aug. 6 for the construction.

Crews will use rapid-bridge replacement technology to remove the existing highway overpass and move the pre-constructed new bridge into position. 

Drivers have endured congestion and slow traffic trying to get around the closure.

"The shutdown is just terrible. Even just trying to come down this way from the West End, we got completely stopped there. I'm just tired of seeing all the construction, to be honest," said John Allarie. "My GPS said 16 minutes to get where it was taking me, and then it took me almost 40 minutes to get here."

Colin Weneck said he doesn't even want to get on a bus.

"It'd be quicker if I walked," he said. "Just stay at home, try to avoid the traffic - that's all you can really do right now."

Businesses in the area say traffic has slowed down since Preston Street was closed.

"Italian Fest was great, but then ever since the bridge closed, everything just kind of slowed down," Adele Melanson of the Farinella Snack Bar said.

Highway 417 will be closed at the same time as the O-Train remains out of service between uOttawa and Tunney's Pasture stations for annual maintenance. The O-Train will be partially shut down until Sunday.

The City of Ottawa is warning motorists to expect "significant traffic and transit impacts" on Friday due to the Hwy. 417 closure, the shutdown of the western extension of the O-Train for maintenance and the Ottawa Redblacks game.

"The peak impacts are expected between 3 p.m. and 11:30 p.m." the city said in a statement. "If you are needing to travel, please expect delays and plan accordingly to allow for extra travel time."
