Severn Bridge's corrosion problem
Engineers on top of the Old Severn Bridge
20m will be spent over the next two years to halt the corrosion
Around 20m will have to be spent on the Old Severn Bridge after engineers discovered it is in a worse condition than previously feared.

Last year, the Highways Agency spent 3m investigating the corrosion levels of the bridge's main cable suspensions.

Engineers said they have opened up a "can of worms".

They began by examining six cables, then eight and finally checked 10. All are reported to be in a worse condition than expected.

The money will be spent over the next two years to halt the deterioration.

One option which may be considered is using a dehumidifier - a solution used on the Forth Road Bridge in Scotland.

Weight restrictions may also have to be brought in for heavy goods vehicles.
