Peerless Pier Caps

The Trenton-Morrisville Toll Bridge (TMTB), originally a 4-lane structure, was build in 1952 by the Delaware River Joint Toll Bridge Commission (DRJTBC). Linking New Jersey and Pennsylvania by carrying U.S. Route 1 over the Delaware River, the structure is a critical transportation link, as Route 1 connects metropolitan Philadelphia with New York City and Washington, DC. The highway also serves as a primary local access route, and plays a major role in meeting regional and national transportation needs associated with trade, commerce, and defense. As it reached the half-century mark, the aging TMTB was unable to keep pace with increases in traffic. In response, the DRJTBC initiated an aggressive campaign to revamp and rehabilitate the deteriorating structure. This article provides an overview of the TMTB rehabilitation project, which featured the innovative use of cantilevered pier caps to facilitate the widening of the bridge, replacing the bridge deck, and improving the approach structures and toll plaza.
