Air Force: The Owners of the UK's Major Suspension Bridges Face Difficult Times as They Investigate the Extent of Corrosion on the Structures' Main Cables, and Try to Decide What Course of Action to Take

Engineers assumed, when suspension bridges were initially constructed, that their cables, whose combined painting, wire wrapping, red lead paste, and galvanized wire was impenetrable to water, would not corrode. In 1998, a National Cooperative Highway Research Program workshop focused on main bridge cable maintenance and assessment. Although focused on some of the United States' oldest suspension bridge cables, the situation in the United Kingdom was also considered. The workshop resulted in an initial draft of a code of practice suggesting that, 35 years after construction, cables should be unwrapped, examined, and analyzed. The author discusses challenges facing aging suspension bridges in the United Kingdom in regard to main cable corrosion, as well as cable dehumidification options.
