THE SECOND SEVERN CROSSING. SUPPLEMENT TO NEW CIVIL ENGINEER - MAY 1996
The supplement celebrates the completion of the construction of the Second Severn Crossing (SSC) between England and Wales. This Anglo-French civil engineering project, with contractors Laing and GTM Entrepose, faced challenges from tides, high winds, and heavy rain, but produced a first class set of bridge structures, including a long suspension bridge. The articles in this supplement describe many aspects of the project. Plans for the SSC began in the mid-1980s. Experience, gained from the financing of the Dartford crossing, strongly influenced the SSC's financial package. Design work on the SSC began in the mid-1980s. One of the most complicated and difficult tasks was to program the operations of a fleet of specialist barges and boats, used to convey construction components to their sites, then lift them into place. Placing the foundation caissons in the wild waters of the Severn estuary was another major challenge. Lifting the final section into place pushed bridge technology to its limits. The bridge is the first in the world to protect its traffic fully from wind as extensive environmental protection measures were built into the SSC tender documents.
