This article describes a new technique for totally enclosing an exposed steel bridge deck with glass reinforced panelling (grp) that is being tried out on the 2km-long 68-span a19 tees viaduct linking both sides of teesside near middlesbrough. The principal aim of this 2.2 million system, which is part of fairclough's 10.8 million repair and maintenance contract for the viaduct, is to provide permanent access for inspecting one of europe's largest steel bridges. However, the panelling will also protect the structure of the viaduct, with the hope that its painting and maintenance costs will be reduced. In addition, all its 565 bearings are being replaced, almost all the 120 expansion joints are being renewed, and the deck is being checked and repaired; in particular, sections damaged by chloride attack (resulting from the use of road salts) are being restored, and precautions are being taken against its recurrence by avoiding the use of concrete. The article gives some details of these engineering works, and discusses the problems that have arisen during the 13 years' life of the viaduct. According to the Department of Transport'S project manager, these problems mostly result from the crossing's size and heavy traffic flow; as it has had no really major repairs of resurfacing since it opened, the department is now attempting to minimise costs by doing all the necessary work together.
