Atlantic City Expressway Third Lane Widening
The South Jersey Transportation Authority (SJTA) wanted to widen the westbound Atlantic City Expressway to provide a third lane from MP 25.0 to 31.8. Among the challenges presented were that the widening had to occur on the inside median of the existing westbound roadway.
SJTA retained RVE under our existing General Engineering Consultant (GEC) contract to provide construction management and inspection services for this project. The overall pavement width of the westbound roadway was widened to provide a new travel lane and shoulder. In addition, the existing lanes and outside shoulders were milled and resurfaced and new signing, guiderail, pavement striping, and delineators constructed.
RVE handled the oversight of all construction activities and schedules to ensure quality and maintenance of operations during construction. Our inspection personnel performed all construction supervision services in accordance with SJTA Roadway and Safety Procedures, NJDOT, and the state police. Also ensured work conformed to current engineering standards and principles used by the USDOT and AASHTO.
Additional services provided included bridge widenings, box culvert extensions, installing overhead sign structures, and installing highway lighting at interchanges. Various Intelligent Transportation System (ITS) components were incorporated along the Expressway, including closed circuit television (CCTV) Cameras, EZ-Pass tag readers, and overhead variable message signs.
The Third Lane Widening Project was constructed in three contracts. In the first, the widening work started at MP 7.7 (GSP) and was taken past the Egg Harbor Toll Plaza at MP 18.5, for a total of 10.8 miles. In Contract 2, the work was from MP 18.5 to MP 25, for a total of 6.5 miles. Contract 3 completed the widening up to MP 31.8 (Route 73), for a total of 6.8 miles.
The improved ITS system monitors traffic and emergency conditions along the roadway and provides the motoring public with vital information, advisories, and traffic updates.
