The mechanical marvel you see above is called the Road Zipper. Lindsay Infrastructure developed the incredible construction vehicle in 1984 as a faster way to set up and adjust road barriers. This conveyor system lifts, rather than drags, heavy “T-top” barriers and gently moves them into place. The barriers are then pinned together to create a wall. Road Zipper has a max operating speed of 10 mph and is designed to work on active roads so roadwork can be done without major closures or traffic delays.
