This video, shot by Maine television station WMTW-8, captures a culvert failure and road collapse from an intense spring storm. It's a teaching tool LTAP/TTAP centers utilize.

com: Tubedute54: I worked engineering of a county hi-way dept. I would design and size culverts for stream crossings. From what I see here the pipe inlet opening had been compromised resulting in it not carrying the required flow. The storm event may have also been more than the design flow could handle resulting in over-topping of the road which never ends well as the berm erodes very rapidly resulting in undermining of the road. It also shows how easily hydraulic pressure can lift a 15-20,000# culvert like it was balsa wood. I have seen these types of culverts carried many feet downstream.

Com: Martin : if this is anything like the uk it will be a badly maintained culvert that was supposed to be looked after by a "public private partnership" but instaed of doing the work they just pocket the money for shareholders and the maintenance never gets done

Com: Kevin: Precisely the reason why the NWS started "Turn Around Don't Drown." You never know what lies beneath a pool of water on a roadway, especially during weather like this.
