Susquehanna River Bridge, Road bridge over Susquehanna River near Harrisburg, United States.
The Susquehanna River Bridge is a toll road bridge on Interstate 83, crossing the Susquehanna River near Harrisburg and linking Dauphin County to York County. It consists of two separate concrete spans, each carrying three lanes of traffic in one direction.
A steel bridge opened at this crossing in 1950, built with materials from Pennsylvania's steel industry. By 2007 traffic had grown enough to require a full replacement, and the current twin concrete structures were put in place.
The bridge sits on Interstate 83, a route that many commuters use daily to travel between central Pennsylvania and Maryland. It is one of the few direct crossings over the Susquehanna in this part of the state, making it a well-used link between the two riverbanks.
The bridge is part of a toll highway, so drivers should be ready to pay before setting out on this route. Traffic tends to build up during morning and evening commute hours, and midday crossings are generally smoother.
The two concrete spans built in 2007 were constructed using a segmental box girder method, which was uncommon for an interstate bridge of this size in Pennsylvania at the time. Keeping the two directions of travel in entirely separate structures, rather than a single deck, was a deliberate choice that differs from many older bridges on the same highway.
