7. Similar incident in Quebec

We were driving from the mountains into Montreal for the F1 race on a very quiet Sunday when we hit a traffic jam, very unusual for a Sunday... same deal. new bridge collapsed.

Boulevard du Souvenir overpass collapse

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. Another collapsed overpass incident occurred on September 30, 2006, also in Laval, on Autoroute 19 where the collapse of the De la Concorde overpass killed five, although this was for totally different reasons.

The overpass was under construction at the time the incident occurred. The company in charge of the project was Beaver Ridge, a company that was under bankruptcy protection and was without a construction license for about four months. Dessau-Soprin was an engineering firm that was supervising the project operations

I agree. That suspension feature was highly engineered for just a cosmetic structure.... marble falls Mar 2018 #18
