HC Deb 07 March 1977 vol 927 c397W
Mr. Watkinson

asked the Secretary of State for Transport what view was taken at the time of the design and construction of the Severn Bridge about the possible effects of unlikely but possible loading conditions on the rocker assembly units.

Mr. Horam

The design of these secondary members was based on a pattern of loading which at the time was considered to be the most severe case.
