Delaware River Port Authority

The Delaware River Port Authority (DRPA), officially the Delaware River Port Authority of Pennsylvania and New Jersey, is a bi-state agency instrumentality created by a congressionally approved interstate compact between the state governments of Pennsylvania and New Jersey. The authority is principally charged with maintaining and developing transportation links between the two states, including four bridges and a mass transit rail line across the Delaware River.
