On June 18, 2000, the southern portion of the Boulevard du Souvenir overpass in Laval, which crosses Quebec Autoroute 15, collapsed into the roadway, killing one and injuring two when cars were crushed underneath the structure. Sixteen beams weighing about 70 tons each fell. The highway was closed for several days while workers removed the debris. The remains of the structure were later demolished as well for safety reasons according to then–Quebec Transport Minister Guy Chevrette. A new overpass was built less than three years later. A similar incident occurred on September 30, 2006, also in Laval, on Autoroute 19 where the collapse of the De la Concorde overpass killed five.
