2011 Suspension Bridge Maintenance

October 2011: Suspension Bridge Hangers. The work entails replacing two of the longest hangers, which are 12 metres and 14 metres long and together weigh around a third of a tonne. They were hoisted into position using a cherry-picker. Straps with strain gauges held the strain while each rod was removed. A further eight hangers are being replaced without the need to disrupt traffic.
