Spanning a combined 6,6km, with 9 viaducts designed to support high-speed rail, the Precast Segmental Viaducts comprise of both single track and double track post-tensioned concrete box girders which will carry the HS2 high-speed lines throughout the route’s Delta Junction. The viaducts are founded on deep-pile foundations, cast in-situ pile caps and piers. They feature the innovative use of a temporary cable-stayed mast and swivel crane, pioneering in the UK and significantly improving construction efficiency.
