Since 2003, the DRJTBC has been working on plans to replace the bridge, improve the safety and traffic flow of its two immediately adjoining interchanges (Taylorsville Road in Pennsylvania and Route 29 in New Jersey), and widen the Pennsylvania approach to the bridge (from four lanes to six). The project was deemed necessary because the original configurations of the bridge, interchanges and roadways suffered from numerous inadequacies. Current design standards call for, at minimum, the addition of an inside shoulder wide (adding to its current width) and an outside shoulder wide (adding to its current width). The closely spaced interchanges on both ends of the bridge require the addition of acceleration and decelaration lanes (the Commission refers to them as "auxiliary lanes"), of which there are currently none.
