Laurels Preserve, Chester County, PAHayes Clark Covered Bridge
Hayes Clark Covered Bridge stands on a private road in the Brandywine Conservancy's Laurels Preserve, between Coatesville and Kennett Square in Chester County. Coveredbridges.net places it over Doe Run, while Uncovering PA says Buck Run. Sources also differ on its length: Uncovering PA gives 75 ft, and coveredbridges.net gives 85.8 ft overall with a 74.2 ft main span. It is closed to vehicles.
Uncovering PA reports that the bridge was first built in 1884, burned in 1963, and was rebuilt in 1971 as close to the original as possible. Coveredbridges.net gives 1871, and a local roads site gives 1971 as the date of the replacement. The same site describes the present bridge as a replica twin of the nearby Speakman No. 2 bridge on Buck Run.
Coveredbridges.net describes the truss as a queenpost variant and gives a deck width of 17.4 ft.
The bridge is on preserve land that the Brandywine Conservancy opens to its members from dawn to dusk. The preserve entrance is on Apple Grove Road, 100 yards off PA 82, about four miles west of Unionville, and its parking area holds about ten cars. Non-members are directed to join before visiting.
