Watson Mill Bridge State Park, Covered bridge in a state park near Comer, Georgia, United States

Watson Mill Bridge is a 229-foot covered wooden bridge over the South Fork of the Broad River, built in 1885 with a Town lattice truss held together by wooden pegs. Its gabled roof has dark shingles and its vertical siding is weathered gray-brown, with a single small rectangular opening on the left half of the side facing the viewer. A low waterfall crosses the river beneath it.

Built in 1885, the 229-foot Watson Mill Bridge is the longest original-site covered bridge in Georgia, held together by a Town lattice truss with wooden pegs called trunnels. The site is listed on the National Register of Historic Places as the Watson Mill Covered Bridge and Mill Historic District. Georgia once had over 200 covered bridges; only 20 remain.

The bridge takes its name from the Watson family's mill, and the surrounding site is listed on the National Register of Historic Places as the Watson Mill Covered Bridge and Mill Historic District. The park near Comer and Carlton keeps picnic shelters, a group shelter and campsites where visitors stop beside the South Fork of the Broad River.

The park has 21 tent, trailer and RV sites plus 3 pioneer camping sites, a group shelter and 3 picnic shelters. Boat rental is available for paddling on the South Fork of the Broad River. A hiking and riding trail follows the river's edge through the surrounding forest.

A long former waterway running through the grounds once channeled water to power a nearby textile factory. Visitors can still trace this industrial waterway today and understand how water power once drove the local economy.
