List of crossings of the River Wye

The Monmouth Viaduct or Chippenham Meadow Viaduct is a 20-arch 183m red sandstone viaduct, with two 23m steel lattice-girder spans over the river. It carried the Coleford, Monmouth, Usk & Pontypool Railway line across the River Wye at Monmouth, Wales. A further river crossing by the Ross and Monmouth Railway was later built nearby. The Coleford, Monmouth, Usk & Pontypool Railway was opened in 1857, running from Pontypool to Monmouth Troy. The single-track line was extended in 1861 to Wyesham Halt on the east side of the viaduct. The bridge which was originally planned to carry the line onwards to Coleford. However, the line terminated at Wyesham and was not extended to Coleford as the Great Western Railway and West Midland Railway did not pursue the extension. The bridge was not heavily used until 1876 when the Wye Valley Railway completed its line from Chepstow and south Wales. In 1883 the Coleford Railway was constructed from Wyesham Junction to Coleford but was closed as being uneconomical in 1916.The viaduct was originally planned to be constructed of wood, but the 1852 floods influenced the engineers to change to stone. The building of the viaduct took exactly ten months. It contains 9,000 cubic yards of masonry and 3,000 cubic yards of concrete. Two arches form the 20m long eastern element of the structure. The bridge was designed by Christopher Firbank and built by Kennards of Crumlin. It was about 50 feet above the water and lay on two 150-foot girders resting on the stone arches. Large crowds assembled to watch the bridge being put into place in 1861. Only the stone parts of the viaduct are extant today.

The River Monnow (Welsh: Afon Mynwy) marks the England–Wales border for much of its 42 miles (68 km) length. After flowing through southwest Herefordshire, England, and eastern Monmouthshire, Wales, its confluence with the River Wye is approximately 1⁄3 mile (0.54 km) south of Monmouth. The Monnow rises near Craswall on Cefn Hill just below the high Black Mountains, Wales. It flows southwards, gaining the waters of its tributaries the Escley Brook and Olchon Brook near Clodock and the waters of the River Honddu, from the Welsh side of the Black Mountains, near Pandy. The river then flows briefly eastwards, to Pontrilas, where it is joined by its largest tributary, the River Dore before again turning southwards. At Monmouth, the Monnow joins into the River Wye with the River Trothy.
