Built circa 1697 at a Lenape Indian trail crossing, Pennypack Creek Bridge is the oldest roadway bridge in continuous use in the nation. Its tri-arch stone span was an important link on the King's Highway, one of America's oldest roads. In 1781, it served American and French combined forces on the march to Yorktown along the Rochambeau Route. Its only major modification was a widening in 1893, and the upstream side remains essentially unchanged from the original.
