Severn Bridge - 40 Year Inspections

40 Year Inspections

During its 40th year of operation, the bridge was inspected to check for corrosion of the suspension cables. According to the Highways Agency, the inspection concluded that the bridge needed restrictions on heavy goods vehicles. Such vehicles are now restricted to one lane on the bridge, with weight restriction signs in place. A system of installing a rubber casing on the cables with dry air circulation is to be used on the Forth Road Bridge and a similar system may be implemented on the Severn Bridge, in a move to halt the progress of the corrosion.
