All eastbound lanes of Highway 417 are closed between the Nicholas/Lees exit to the Vanier/Riverside exit.
A tractor-trailer slammed into the cement barrier on the 417 eastbound in that stretch around 5:20 a.m. Thursday. Traffic is currently being diverted onto the Nicholas off-ramp eastbound and Lees Avenue.
The Nicolas eastbound on-ramp is also closed because of the accident; however, the highway is open at Riverside Drive.
The truck was spilling fuel earlier but fire officials say that’s now under control.
There are several downed hydro-poles as a result of the crash.
OPP, Ottawa Police and Ottawa Fire Crews are on scene and emergency officials say the closure may last several hours.
Police are asking motorists to avoid the area or make alternate travel arrangements.
