Watson Mill Bridge State Park is a 1,018 acre (4.12 km²) Georgiastate park located near Comer and Carlton on the South Fork of the Broad River. The park is named for the Watson Mill Bridge, the longest original-site covered bridge in Georgia, which spans 229 feet (69.73 meters) across the South Fork River. The bridge, being more than 100 years old, is supported by a town lattice truss system held firmly together with wooden pins. Georgia once had over 200 covered bridges, but only 20 now remain. The park also offers a scenic nature trail and a new hiking/horse trail that winds through the thick forests and along the river’s edge.
