Forth Road Bridge Bearing Replacement
As part of a regular maintenance programme, work commenced on site in May 2010 to replace all the bearings on both approach viaducts on the north and south of the Forth and will continue until the end of 2012. The approach viaducts are supported by reinforced concrete piers with steel bearings to allow the bridge deck to move to compensate for changes in temperature and traffic loading. The project involves jacking up the bridge deck to allow removal and replacement of the existing bearings, with the concrete being strengthened at the jacking points by the addition of reinforced concrete corbels added to each side of the piers.
