Saltburn Viaduct

Saltburn Viaduct, also known as Upleatham, Riftswood, or Skelton Beck Viaduct, is a railway bridge in Redcar and Cleveland, North Yorkshire, England. Built as an extension of the Redcar and Saltburn Railway, it primarily consists of brick construction. The viaduct opened to passengers in 1872 but transitioned to freight-only use in 1957, a role it continues to serve today as part of the Boulby line.

Designed by Thomas Elliot Harrison, the viaduct's architect, it stands at 156 feet tall with ten piers and eleven arches, each spanning 60 feet. Two piers are embedded in Skelton Beck, contributing to its total length of 738 feet on a north-south axis. Initially carrying two lines, it was reduced to a single track in 1969 following the cessation of passenger services.

Locally referred to as Riftswood or Marske Mill Viaduct due to its location, the structure is Grade II listed since May 1999. In 2006, £446,000 was spent on refurbishment addressing water ingress, using bricks from a Birtley brickworks to maintain structural integrity without modern materials that could cause cracking.
