An abandoned railway bridge which crosses the River Tweed a mile (1.7 km) west of Peebles, the Neidpath Viaduct (occasionally known as the Queen's Bridge) was built in 1863 for the Symington, Biggar and Broughton Railway. This picturesque viaduct crosses the river at an angle and is said to be one of the finest examples of skew-arch construction in Scotland. Constructed in buff rock-faced sandstone ashlar, the viaduct was the work of a local architect, Robert Murray, working in conjunction with George Cunningham the railway company's engineer. Its eight arches each span 9.9m (32½ feet) and carry the railway 9.75m (32 feet) above the river. It features decorative cast-iron railings along its parapet.
The viaduct fell out of use when the section of the line between Peebles and Broughton closed on 7th June 1954 but is now A-listed owing to its architectural importance. The Neidpath Tunnel is located just to the east.
