Route 42 is a state highway in the U.S. stateofNew Jersey, in the Camden area. It runs 14.28 mi (22.98 km) from an intersection with U.S. Route 322 and County Route 536 SpurinMonroe Township, Gloucester County to an intersection with Interstate 76 and Interstate 295inBellmawr, Camden County. The route is a mix of freeway and divided four–lane arterial road. The southern portion of Route 42 is a local arterial route and one of several highways comprising the Black Horse Pike, a road that runs from Camden to Atlantic City. The northern portion is a six– to eight–lane freeway referred to locally as the North–South Freeway (or simply the 42 Freeway) that is directly connected to the Atlantic City Expressway. Major intersections along the route include the Atlantic City Expressway and the southern terminus of Route 168inTurnersville, another intersection with Route 168 in Blackwood, and Route 41 and Route 55inDeptford Township.
Route 42 was originally designated in 1927 to run along the Black Horse Pike between Ferry Avenue in Camden and the present U.S. Route 40/U.S. Route 322 split in the McKee City section of Hamilton Township, Atlantic County. In 1953, the southern terminus was cut back to its current terminus in the Williamstown section of Monroe Township to avoid the concurrency it shared with U.S. Route 322. After the completion of the North–South Freeway between Bellmawr and Turnersville in 1959, Route 42 was moved to this freeway, and the Black Horse Pike north of Turnersville became Route 168. The freeway portion of Route 42 has been improved many times and is projected to see more improvements, including reconstruction of the dangerous and congested interchange with Interstate 76 and Interstate 295 in Bellmawr.
