SEVERN CROSSING REFURBISHMENT

Maintenance carried out to the Severn Bridge has prepared it to cope with predicted traffic levels well into the next century. Major refurbishment works which included replacing suspension hangers, renewing welds and jacking up 120m high columns inside the towers were carried out in a remarkably unobtrusive manner. Brief details are given of the work involved which was hampered by difficult access to the bridge which limited the size of components and vehicles used. Part of the project involved building 4 new 400mm diameter columns inside each wing of the existing towers. The columns were jacked up on new foundations in the river bed and a total of 8000t extra live load capacity provided. The project also included work on the Wye Bridge where cable configuration was altered, the height of the towers increased and the pair of cables at each tower replaced by two pairs. (TRRL)
