Tinsley Viaduct
Tinsley Viaduct is a two-tier road bridge in Sheffield, England; it was the first of its kind in the United Kingdom. It carries the M1 and the A631 for a distance of 3,389 feet (1,033 m) over the Don Valley, from Tinsley to Wincobank, also crossing the Sheffield Canal, the Midland Main Line and the former South Yorkshire Railway line from Tinsley Junction to Rotherham Central. The Supertram route to Meadowhall runs below part of the viaduct on the trackbed of the South Yorkshire Railway line to Barnsley.
