Video: Freeport Maine Culvert Failure and Road Collapse
A colleague of mine sent me an amazing video of a culvert failure and subsequent road collapse in Freeport Maine during a storm. The culvert was unable to accommodate the high volume of water, and it was backing up behind the roadway embankment like a dam, and spilling out onto the roadway.
