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. In a span of about 3 minutes, the entire section of road collapsed and was washed downstream. I don’t know the exact date the video was taken, but it appears to be in August of 2008.
