Wendover Dean Viaduct

About

The Wendover Dean Viaduct is a railway viaduct currently under construction that will carry the High Speed 2 (HS2) railway line across farmland between Wendover and Great Missenden, Buckinghamshire, England. Approval for the viaduct's construction was issued in 2017 via the High Speed Rail (London - West Midlands) Act 2017; its design was publicly revealed two years later. In June 2021, Buckinghamshire Council also approved plans for the viaduct.

Design revisions centred around improving its aesthetics and minimising its impact on the countryside. Construction of the main deck took place between late 2021 and 2024, although high speed trains will not traverse the structure until several years after this point.
