A collision on Hwy. 401 westbound between Burnham and Division streets had the westbound lanes down to just the left lane Wednesday, Nov. 6 just before 4 p.m.
Traffic is getting through, but slowly.
OPP say that EMS and fire are also on the scene and that the crash involves a pick-up truck, which rolled into the ditch.
The driver was transported to hospital but his condition is currently unknown.
OPP have started their investigation but there is currently no estimate on how long the lane reduction will be in place.
