A collision involving a dump truck has led to the closure of all westbound express lanes on Highway 401 between Mavis Road and Mississauga Road in Mississauga, Ontario.

Dump Truck Collision Causes Major Delays

The incident occurred on May 4th, late Monday afternoon just before 5:00 PM. According to the Ontario Provincial Police (OPP), the dump truck experienced a mechanical failure while travelling eastbound.

Gravel Spill Impacts Westbound Traffic

The mechanical failure caused the truck to lose control and collide with the concrete guide rail separating the eastbound and westbound lanes. This resulted in a significant amount of gravel spilling across the highway, impacting the westbound lanes and creating a hazardous driving condition.

Lane Closures and Traffic Management

All westbound express lanes are currently closed. Traffic is still able to proceed through the collector lanes, but substantial delays are anticipated. The OPP is managing the situation and advising drivers to exercise caution.

Cleanup Efforts Underway

Cleanup efforts are expected to take several hours, involving the removal of spilled gravel and assessment of potential roadway damage. Drivers are encouraged to use alternative routes or check traffic reports before travelling.

Investigation and Safety Reminders

The cause of the mechanical failure is currently under investigation. Authorities are working to restore normal traffic flow as quickly and safely as possible. The OPP emphasizes the importance of regular vehicle maintenance to prevent similar incidents.

Motorists are urged to stay informed through OPP highway reports, traffic apps, and local news broadcasts. Patience and cooperation are requested as emergency crews work to resolve the situation.
