Nestled in scenic Grassmere Park, Pennsylvania, the Welle Hess Covered Bridge No. S1 has spanned its crossing since 1871. This historic structure showcases the distinctive Burr arch truss design—a combination of a wooden arch and multiple kingpost truss that provided exceptional strength for 19th-century bridge builders.

Current Status: Open to traffic, allowing visitors to drive through and experience this piece of living history.

Visiting Tips: Early morning offers the best photography light, with soft shadows highlighting the weathered wood siding. Park safely off-road and capture shots from the creek bed below for dramatic angles. Fall foliage transforms the surrounding landscape into a stunning backdrop. Respect private property boundaries near the bridge approaches.
