The US Marines built a temporary bridge across the Colorado River so Light Armored Reconnaissance could cross it. Here's how they did it. Following is a transcript of the video.

US Marines built a temporary bridge. Light Armored Reconnaissance (LAR) needed to cross the Colorado River. The 7th Engineer Support Battalion was put to work. Here's how they built the bridge. Trucks launch folded bridge sections into the water. They pop open. Boats are hooked to the bridge pieces. The boats drive the sections in place. Each piece hooks together like Legos. The ends are ramps that slope up. Once it's secure, military vehicles are able to cross the river.
