The Galton Bridge is a cast-iron bridge in Smethwick, near Birmingham, in the West Midlands of England. Opened in 1829 as a road bridge, the structure has been pedestrianised since the 1970s. It was built by Thomas Telford to carry a road across the new main line of the Birmingham Canal, which was built in a deep cutting. The bridge is 70 feet above the canal, making it reputedly the highest single-span arch bridge in the world when it was built, 26 feet wide, and 150 feet long. The iron components were fabricated at the nearby Horseley Ironworks and assembled atop the masonry abutments. The design includes decorative lamp-posts and X-shaped bracing in the spandrels.

Smethwick is an industrial town in Sandwell, West Midlands, England. It lies 4 miles (6 km) west of Birmingham city centre. Historically it was in Staffordshire and then Worcestershire before being placed into then West Midlands county.
