§ 64. Mr. Copeasked the Secretary of State for Transport if he will make a statement elucidating further the nature of the trouble affecting the rocker assemblies of the Severn Bridge.
§ Mr. HoramThe deck members of the three spans of Severn Bridge are not structurally connected, the end of each576W span being supported on two rockers. The major part of the bridge weight and traffic loading is carried by the main cables and the hangers. The rockers carry a small part of this total loading. If heavy vehicles bunch up on the slow lane of one carriageway, some of these rockers and their attachments could be damaged causing a step in the roadway.
