Route 70, Route 38 to Cooper Avenue
McCormick Taylor, in cooperation with the New Jersey Department of Transportation (NJDOT), led the roadway rehabilitation of 9 miles of Route 70 traversing multiple municipalities and counties, which included pavement reconstruction and resurfacing, stormwater management and drainage enhancements, utility upgrades, traffic signal upgrades, and other operational and pedestrian improvements.
The Challenge
The Route 70 Corridor Improvement Project encompasses approximately 9 miles of Route 70 between Route 38 (Mile Post 0.00) and Cooper Avenue (Mile Post 8.80) spanning the municipalities of Pennsauken and Cherry Hill Townships in Camden County, NJ and extending into Evesham Township, Burlington County, NJ. The existing roadway corridor included various types of pavement cracking, raveling, and deterioration with other notable deficiencies identified within the sidewalk, curbing, curb ramps, signalized intersections, and guiderail. In addition, multiple culverts along the corridor were in need of replacement, including the Cropwell’s Brook culvert (MP 3.99), which ranked within the state’s top 20 list of culverts requiring replacement.
How We Helped
McCormick Taylor led the engineering design for the project aiming to improve the deteriorated pavement and outdated infrastructure along this heavily traveled corridor through a combination of milling, resurfacing, and full-depth pavement reconstruction. Improvements included: the replacement of several miles of deteriorated underground utility infrastructure, drainage and stormwater management facilities, and three (3) culverts; upgrades to 28 traffic signals including new adaptive signal equipment, a new NJDOT ITS system, CCTV cameras and four (4) dynamic message signs (DMS); and improvements to pedestrian facilities including the reconstruction of 350 curb ramps to ADA standards, reconstruction of existing sidewalks, and the installation of new sidewalks to fill gaps in the network. Milling and resurfacing of NJDOT’s jurisdictional jug handles along Route 70/Cuthbert Boulevard and Route 73/Route 70 interchange ramps were also included in the design plans.
Results
Overall, the project will enhance safety, reduce congestion, improve traffic flow, and provide safer, more accessible facilities for motorists, pedestrians, and surrounding communities. This project required a balancing of motorist mobility, utility installations, material availability during COVID, interaction with three townships and two counties and the establishment of multiple construction work zones.
