The Erskine Bridge is a multi-span cable-stayed box girder bridge connecting West Dunbartonshire with Renfrewshire across the River Clyde, forming part of the A898.
The bridge is used by a high volume of motor vehicles, cyclists and pedestrians and consists of a two-lane dual carriageway with footpaths and cycle lanes on either side. The main bridge span measures 1,001 feet, with a total length of 1,721 feet.
In 2013 SWGR supplied engineers to Highway Barrier Solutions to deliver works to the traffic barrier on Erskine Bridge for Transport Scotland, improving the bridge’s safety for its users – seeing the completion of a four-year programme of improvement works to the bridge.
This project involved the careful removal of existing plates, which required SWGR’s engineers to gouge into the bridge deck in order to remove existing supports. Repairs were carried out to the bridge structure as well as grind-off and preparation works for the receipt of the newly designed structural supports.
Setting-out works were carried out by the main contractor, before SWGR engineers installed barriers from south to north on one carriageway and then from north to south in the other direction, completing the bulk of the work.
Despite the adverse weather conditions faced by the team on the exposed site, they maintained a high level of productivity through establishing an efficient routine on site, which allowed for the project to be delivered ahead of schedule and within budget.
