DURING ROAD REHAB PROJECTS, CHICAGO DOT MANAGES URBAN HIGHWAY TRAFFIC WITH A ZIP

Despite their high cost and specialized application, zipper-walls are proving to be an effective way to manipulate highway workzone space and improve traffic flow for drivers in other lanes. This article relates how these moveable barriers have been successful during the restoration of South Lake Shore in Chicago as well as the current rebuilding of the 7.8 mile Chicago Skyway overpass. Zipper-walls, which consist of concrete segments of indefinite length, are constructed using a hydrostatically powered transfer vehicle that travels at 5 mph.
