Thames Barrier

Thames Barrier – London UK

Architect: Sir Roger Walters.

Date Constructed: 1974-1982

The Thames Barrier is an iconic architectural design conceived by Sir Roger Walters, along  with the barriers engineering designed by Rendel, Palmer and Tritton for the Greater London Council, based on an idea by Charles Draper in 1969. The site at New Charlton was chosen because of the relative straightness of the banks, and because the underlying river chalk was strong enough to support the barrier. Work began at the barrier site in 1974 and largely complete by 1982.

The barrier also consists the flood defenses, which were raised and strengthened for 11 miles down river. Built across a 520-metre wide stretch of the river, the barrier divides the river into four 61-metre and two, approximately 30 meter navigable spans. There are also four small non-navigable channels between concrete piers and abutments.
