The Highways Agency was yesterday expected to announce weight restrictions must remain in place on the Severn Bridge after an investigation into the bridge's corroded cables.
A spokesman for the Agency told NCE that inspections of the cables have been completed but a full analysis of the findings will not be available till later this year.Only once the analysis has been completed will the future of the M48 Severn crossing be decided. Weight restrictions were originally introduced in September last year after corrosion of the cables reduced the load carrying capacity of the bridge. At the time NCE revealed that in some cases the corrosion in the Severn Bridge's cables was found to be so bad that the cables had disintegrated (NCE 21 September 2006).Heavy goods vehicles are currently only allowed to travel in one lane in each direction and this will continue until a long term strategy is decided.The Agency began its £3M investigation at Easter last year after corrosion was discovered in the cables of the forth bridge. Water entering the cables during construction or through cracks in the paint work during operation was thought to be the main cause of the damage.
