Spanning the Delaware River to connect New Jersey to the First State, the four southbound lanes of the Delaware Memorial Bridge handle more than 17 million vehicles every year. The bridge is a major part of the north-south transportation corridor between New York City and Washington, D.C. To make the crossing faster and more efficient for motorists, the Delaware River and Bay Authority (DRBA) needed to upgrade the bridge’s toll collection system. The existing infrastructure featured select toll lanes accepting only cash and other lanes accepting only E-ZPass. With three-quarters of all drivers now using electronic payment methods, the system was quickly becoming outdated.
To reduce congestion and ensure tolling accuracy, the authority decided to replace the old system with a state-of-the-art Integrated Toll Collection System (ITCS) and add electronic lane signs that clearly show acceptable payment methods. The improvements will allow all of the bridge’s toll lanes to accept cash, E-ZPass, or both forms of payment. The improvements offer DRBA the flexibility to quickly adapt to traffic conditions and easily change the toll collection signs indicating which form of payment is acceptable in each toll lane.
Gannett Fleming developed a traffic control plan so traffic could move safely through the plaza and across the bridge during construction. Because only one of the toll lanes had been built to handle oversize loads, the creative plan featured a way to accommodate oversize vehicles whenever that lane was closed.
