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.
This list includes active road, railroad, foot, and trail bridges, dams, fords, ferries, and historic crossings.
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.
