CONCRETE BRIDGES: AN IMPORTANT 25-YEAR SPAN

The author considers the most important changes in concrete bridge design and construction. The first significant factor was the introduction of pre-stressed concrete and major bridges such as the Clifton Bridge, Nottingham and the Medway Bridge were built using the cantilever method. The Hammersmith flyover was the first box beam structure using precast segmental construction. Precasting, coupled with other developments in factory production had a great influence on the design of short and medium spans. Bridge building gained momentum in the early 1960's from the motorway construction programme and about 85 per cent of all bridges built in the late 1960's were of concrete construction. Although design standards have changed in the last 25 years, new techniques in construction, analysis and the use of materials have given more scope to the ingenuity of the designer. The author describes some original solutions, such as the sliding technique at Frodsham and the extrusion process at Sonning, to the problem of keeping railway lines open. Possible future developments are outlined. (TRRL)
