Take Frankford Avenue over the Pennypack Creek in Holmesburg and you've just traveled on the nation's oldest stone-arch bridge - the very same bridge that carried American and French troops en route to Yorktown, VA during the Revolutionary War. The 315-year-old bridge's history is more visible thanks to a new blue state historical marker.

On October 13 the Holmesburg Civic Association, Friends of Pennypack Park, representatives of the Washington-Rochambeau National Historic Trail, elected officials, and residents commemorated the marker's dedication with a celebration at the bridge.

Jessica Lopez and Lucia Volpe were on hand to capture the celebration, reporting  for NEast Philly and Philadelphia Neighborhoods, and created this video:
