Gibson's Bridge, also known as Harmony Hill Bridge, was built in 1872 by Edward Hall and Thomas Schull after an earlier bridge built in 1870 was destroyed by a flood in 1871. The county commissioners opened construction to auction the following year and received six bids, and the original cost was $2,666. The bridge is 78 feet long and 14 feet wide, using a Burr arch truss design. Located two miles south of Downingtown, it spans the East Branch of Brandywine Creek and connects East and West Bradford Townships. Once one of eleven covered bridges spanning the East Branch of the Brandywine, it is the only one still standing. Its name came from local farmer James Gibson, who owned the land adjacent to the bridge on the east. A trolley line between West Chester and Coatesville once had a stop at the bridge's east end. The bridge was repaired and strengthened in 1959 for $3,470. In 1999, Hurricane Floyd cracked the support, and repairs costing $650,000 took more than four years.
