Tintern Wireworks Branch

The Tintern Wireworks Branch was a short branch line on the Wye Valley Railway, crossing the River Wye between Monmouthshire, Wales, and Gloucestershire, England. It was completed in 1874 and opened on 1 November 1876; the reason for the delay was that the Wye Valley Railway, into which the branch line fed, was not completed until the latter date. It closed in 1935 when the rails buckled in the heat of the summer.

The bridge that carried the line over the Wye, known as the Tintern Wireworks Bridge or Old Tramway Bridge, is now used as a footpath, but in 2022 and 2023 has been temporarily closed for repair.
