The Governor Harry W. Nice Memorial Bridge (also known as the Potomac River Bridge) and opened in 1940 was dedicated to Md. Governor Harry W. Nice (1877-1941) and MD Republican Governor 1935-1939.

is a 1.7-mile (2.7 km), two-lane continuous truss bridge that spans the Potomac River between Newburg in Charles County, Maryland and Dahlgren in King George County, Virginia, USA.[1] The bridge is narrow (one 11-foot (3.4 m) lane in each direction with no shoulders), steep (up to 3.75 percent grade). 1

The bridge, at a dramatic turn in the river, marks the dividing line between the Lower Potomac Estuary and the Upper Estuary. ... At approximately this point, a famous ferry ran from Morgantown, Md. to Mathias Point in Virginia, as early as 1705. The ferry was part of the shortest route between the capitals of Maryland and Virginia and served as a principal link in the journeys of many early Americans, including George Washington, George Mason, and other founding fathers. Nearby is also the site of one of the river crossings by John Wilkes Booth after his assassination of Abraham Lincoln. 2
