Gerrards Cross Tunnel is a 310m long railway tunnel in Gerrards Cross, Buckinghamshire, on the Chiltern Main Line. The purpose of the tunnel was to enable a new Tesco supermarket to be built over the railway line.
During construction of the tunnel, it partially collapsed on 30 June 2005. No-one was injured in the accident, although a train heading towards the tunnel when it collapsed had to perform an emergency stop.
Geo-Design were members of a specialist team appointed to investigate the root causes of the collapse of a large span (20m), pre-cast segmental arch-fill structure, some 300m in length over a live railway.
