A commercial truck towing a dump trailer in a raised position struck the Cambie Road overpass on Knight Street in Richmond, British Columbia, around 7:15 a.m., forcing the closure of all southbound lanes.The trailer became lodged against the structure, and the impact detached the truck cab from the trailer.
Although no injuries were reported, officials ordered immediate inspections to assess possible structural damage.

Engineers and transportation authorities examined the overpass for cracks, weakened supports, and other hidden damage before determining whether it was safe to reopen.The incident caused significant traffic congestion and disrupted commercial transportation across the region.
The crash highlights a recurring problem in British Columbia, where over-height trucks frequently collide with bridges and overpasses.
Common causes include raised truck beds, improperly measured loads, and inadequate awareness of height restrictions.
Safety experts and industry groups are calling for stronger prevention measures, including over-height detection systems, improved driver training, real-time fleet monitoring, and regular infrastructure audits.
As transportation engineer Dr. Steven Fong noted, “No single tool can eliminate accidents—effective prevention depends on a culture of accountability shared between drivers, fleet operators, and highway authorities.”
The incident demonstrates how a single oversight can disrupt transportation networks and reinforces the need for better technology, training, and infrastructure safety measures.
