Abstract:

Precast concrete median barrier curb is being used temporarily to protect both workmen and traffic through the 3.1-mile long construction zone of a widening project along the Garden State Parkway in Bergen County, New Jersey. The 51-in. high precast curb units are placed directly on top and along the inside edge of the existing two-lane northbound and southbound roadways while construction proceeds within the media area to build one additional lane in each direction. The curb sections are interlocked end-to-end. This method of separation of workmen from traffic is expected to greatly improve safety through the construction zone over the heretofor accepted method of using timber curb barrier. After substantial completion of the one-lane-in-each-direction-widening, the 20-ft long curb units will be relocated to their permanent positions in the Parkway median. Two lanes of traffic in each direction are being maintained through the 18-month 18-month long construction period which began in November,
