Frankford Avenue Bridge
The Frankford Avenue Bridge, also known as the Pennypack Creek Bridge, the Holmesburg Bridge, and the King's Highway Bridge, erected in 1697 or 1698 in the Holmesburg section of Northeast Philadelphia, Pennsylvania, is the oldest surviving roadway bridge in the United States. The three-span, 73-foot-long (22 m) twin stone arch bridge carries Frankford Avenue ( U.S. Route 13) over Pennypack Creek. The bridge, built at the request of William Penn, was an important link on the King's Highway that linked Philadelphia with cities to the north ( Trenton, New York, and Boston). Over it crossed anyone who traveled by horseback or coach from the northern colonies to the First or Second Continental Congresses, such as John Adams, from Massachusetts. In 1803, it was paved, and a toll booth was added at its south end. The bridge was widened in 1893 to accommodate streetcars. It remains in use today. The bridge was designated a National Historic Civil Engineering Landmark by the American Society of Civil Engineers in 1970. It was listed in the National Register of Historic Places in 1988. Note: not to be confused with the Frankford Avenue Bridge over Poquessing Creek, built 1904, also on the National Register.
