An intrusive inspection will be carried out on the UK's Humber Bridge suspension cables this summer after a scoping study conducted last year revealed similar defects to those found on the Severn and Forth bridges.
Bridge master and engineer Peter Hill said: 'It's highly likely the remediation work will be needed, no matter how well the bridge is constructed it will still corrode.' The inspection will involve exposing the wires and driving a wedge between them to expose any damage.
Hill will install acoustic monitoring equipment to listen for any wires snapped or damaged during the inspection. If damage is found, dehumidification systems will be fitted between 2008 and 2010.
The Tamar bridge is not expected to be affected by this corrosion problem as its 49mm diameter strands within the cables have a smaller vulnerable surface area and twist along the length reducing void space.
