Whenever we cross a bridge we put our trust in the civil engineers who built it. We trust that it will safely get us from one destination to another. But in life mistakes do happen and bridges do collapse.

In this video, we bring you the harrowing demise of several bridges that were so badly constructed they fell apart causing untold damages. There's the I-35W Mississippi River bridge which spanned across an impressive eight lanes and carried Interstate 35W across the Saint Anthony Falls of the Mississippi River in Minneapolis, Minnesota, United States.

The bridge, completed in 1967, carried over 140,000 vehicles daily. In August of 2007, it collapsed resulting in the death of 13 people and injuring 145. It was assumed that a design flaw was the likely cause of the accident.

There's also the Ironworkers Memorial Second Narrows Crossing bridge located at the Second (east) Narrows of Burrard Inlet in Vancouver, British Columbia, Canada. The bridge connected Vancouver to the North Shore of Burrard Inlet and on June 17, 1958, collapsed during its construction leading to many deaths. Want to know what went wrong?
