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