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 modify roadblocks.

Road Zipper has a maximum operating speed of 10 mph and is designed to operate on active roads so roadworks can be completed without major closures or traffic delays.
