Small Dean Viaduct

Small Dean Viaduct is a viaduct currently under construction in Buckinghamshire which will carry the High Speed 2 railway line.
Approval for the viaduct was granted by Buckinghamshire Council in April 2023.
The viaduct is long and will pass over the A413 road which will be realigned. A shared-use path will also be provided.
The viaduct will have a low profile with the underside of the viaduct above the road surface below. It will be supported by five Y-shaped piers and girders made from weathering steel.
