According to county records, Chester County once had 85 covered bridges, 21 of which were shared with other counties.  The earliest recorded covered bridge in Chester County was built in 1807 and the most recent in 1899.  Only 15 covered bridges remain today, the oldest being the Hall's Sheeder Bridge built in 1850.  The covered bridge played an important part in the transportation system of the County throughout the 19th century.  Many of the bridges were built to serve local mills and the transportation of agricultural produce to market.

Of the 1,500 covered bridges that once stood in the state of Pennsylvania, as of 2019, approximately 200 remain.
