Gibson's Covered Bridge, also called Harmony Hill Bridge, is a historic wooden covered bridge in Chester County, Pennsylvania, that spans the East Branch Brandywine Creek between East Bradford Township and West Bradford Township. Built in 1872, it is a 78-foot Burr truss bridge, combining an arch with a multiple-kingpost truss for strength. Its stepped portals and horizontal clapboard siding reflect traditional regional covered bridge design. Listed on the National Register of Historic Places in 1980, it remains part of the small surviving group of nineteenth-century covered bridges tied to the Brandywine Valley's rural road-building history, despite damage and closure after Hurricane Ida flooding in 2021.
