It was traffic chaos on Highway 401 Wednesday morning after all westbound lanes were closed for hours due to two separate crashes.

Shortly before 8 a.m. near Homer Watson Boulevard a car and dump truck collided. The driver of the car was taken to hospital with minor injuries.

As drivers swerved to avoid that collision, a second crash happened on the highway near the Grand River Bridge. In that case at least two trucks and a car were involved.

Emergency crews were on scene for hours cleaning up the mess.

The Ministry of the Environment and Transportation were also on scene to deal with the debris and a large fuel spill from both crashes.

Cambridge OPP Staff Sgt. John Mraud says “Both of these separate collisions resulted in a huge diesel spill, we’ve been told about 250 litres of diesel on the highway.”

While the right lane reopened shortly before 11 a.m., around noon the highway remained backed up past Highway 24/Hespeler Road as traffic trickled through.

All lanes were expected to reopen by around 1 p.m.
