Bigsweir Bridge, Road bridge in Trellech United, United Kingdom.
The iron arch bridge stretches 50 meters across the River Wye, connecting Gloucestershire in England to Monmouthshire in Wales.
The bridge, constructed in 1827 as part of a turnpike road between Chepstow and Monmouth, features cast iron components from Merthyr Tydfil.
The crossing point marks the boundary between England and Wales, with separate Grade II* heritage listings for each side of the structure.
Traffic signals control the single-track passage across the bridge, allowing vehicles to cross the A466 road in alternating directions.
The structure stands at the normal tidal limit of the River Wye, where navigation authority transfers to the Gloucester Harbour Trustees.
