Susquehanna River
The Susquehanna River flows between Cecil and Harford Counties. U.S. 1 connects the two across Conowingo Dam. 05/29/05

U.S. 1 was the original highway linking Washington, D.C., Baltimore, and Philadelphia, Pennsylvania. The US highway was superseded in importance with the completion of Interstate 95 and the Northeastern Expressway. However outside of the urban areas, the US Highway still plays a vital role in movements throughout Cecil and Harford Counties.
