Old Alton Bridge, Iron truss bridge in Denton County, United States.

Old Alton Bridge is a reddish-brown iron truss bridge over Hickory Creek in Denton County, Texas, connecting Denton and Copper Canyon. Its sides are formed of diagonal and vertical iron members in open triangles, with a horizontal deck below, a top chord above, and railings along both sides of the single-lane deck. A main span leads into a secondary angled section rising to the right.

The King Bridge Company erected this crossing in 1884 when a reliable link between settlements north and south of the creek was needed. The structure carried traffic for over a century before closing to vehicles in 2001 and becoming a trail crossing instead.

People know this crossing as Goatman's Bridge after stories of strange happenings tied to a local goat farmer who vanished in 1938. That history draws curious visitors who come after dark hoping to experience something unusual near the old metal frame.

The bridge now links the Elm Fork and Pilot Knoll Hiking and Equestrian Trails, so walkers and riders cross it while vehicles no longer do. The deck is single-lane and narrow, so pass in single file. The metal deck and railings can be slick after rain.

The iron beams show fastening techniques from the late 1800s where forged rivets hold individual components together. This construction method is rare to see today and marks the structure as a recognized example of American engineering from that era.
