De la Concorde overpass, Road bridge in Laval, Quebec, Canada.
The De la Concorde overpass spans multiple lanes above Quebec Autoroute 19, connecting residential areas with main transportation routes in Laval.
The structure, built in 1970 with a planned 70-year lifespan, experienced a catastrophic collapse of its south lane section in September 2006.
The incident prompted nationwide discussions regarding infrastructure maintenance and led to changes in Canadian bridge inspection protocols.
Regular structural assessments and reinforcement work now take place on the rebuilt overpass to maintain safety standards for daily commuters.
Five granite memorial stones mark the location where vehicles and their occupants were trapped under 65 feet of concrete during the collapse.
