Award:

The Channel Tunnel Rail Link crosses the A1090, Thurrock Marshes, the London Tilbury Southend Railway, a LaFarge Access bridge, the northbound Dartford Tunnel exit and underneath the Queen Elizabeth Bridge by way of a 1 km long incrementally launched prestressed concrete viaduct.

Tony Gee provided the independent check of all permanent works. Checks included major bored piles in high strength low density chalk, pilecaps tight against the LTS rail corridor and sequential time dependent analysis of the 23 45 m long segments during the launching and prestressing sequence.
