A part of the newly inauguratedbridge spanning the Songhua Rivercollapsed on August 24, 2012, at 5 am, killing 3 people and injuring 2 others. Problemsseem to have occurred due to the weight of trucks using the bridge. The bridge was designed to handle 55 tons, but the combined weight of heavy trucks, amounting to at least 500 tons, caused the bridge to collapse. The collapse was blamed mostly on the construction design and on the project's having been finished too quickly and on traffic controllers having allowed, onto the bridge, vehicles of excessive weight.
