List of crossings of the Susquehanna River

List of Susquehanna River crossings proceeding upstream from the river mouth at the Chesapeake Bay in Maryland, United States, generally northward through Pennsylvania toward the main branch headwaters in New York. The West Branch crossings are listed afterward.

This list includes active road, railroad, foot, and trail bridges, dams, fords, ferries, and historic crossings. Presently it does not include historic ferry crossings. Railroad lines are generally as shown on the USGS topographic maps, which may not have been updated to reflect the creation of Conrail in the 1970s, which absorbed many lines in this area.

Main Branch crossings are listed from the mouth of the river in the Chesapeake Bay up to the source at Otsego Lake in Cooperstown, New York.

In a geological sense, the Chesapeake Bay is just the ria, submerged valley, of the Susquehanna River. In that sense the Chesapeake Bay Bridge Tunnel and the Chesapeake Bay Bridge crossings precede those in the conventional list below.
