The Shin Railway Viaduct (also known as the Invershin Viaduct or Oykel Viaduct) is a railway viaduct that crosses the Kyle of Sutherland.The viaduct carries the Far North Line between Inverness and Wick and Thurso. Invershin railway station is at the north-eastern end of the viaduct, while Culrain railway station is a short distance to the south.
It was built for the Sutherland Railway by engineers Joseph Mitchell and Murdoch Paterson.[1]
The railway opened to traffic on 13 April 1868.[2]
It crosses the river with a single span, longer than that used at the Dalguise Viaduct by Mitchell four years earlier.[3] The deck which carries the track sits on top of rather than between the truss girders.[3] There are two semicircular stone arches in the approach viaduct to the south, and three to the north.[1]
A footbridge was added to the northern side of the viaduct in 2000. This is now part of National Cycle Network Route 1.
