Contractor 2393 Ringway has completed work on a tricky project to replace Stile Farm Bridge, which crosses the Great Stour River near Chilham in County Kent, south-east England.
Built in the 1920s, the bridge was in a severe state of disrepair resulting in weight restrictions of just 3tonnes.
The new structure has a 16m span and is constructed using pre-cast concrete, with pre-stressed steel-reinforced beams based on cast in-situ abutment, and enables the bridge to carry heavier traffic.
As well as helping to ease the flow of traffic in the area, the bridge is also accessible for crossing pedestrians, and to protect fish life during the spawning season in the renowned fishing river. Ringway installed a temporary crash deck before demolishing the old bridge and cofferdams for the abutment construction.
Ringway also constructed a footbridge on scaffolding to maintain pedestrian access across the fast-flowing river. The lane's narrow access via a level crossing restricted the size of equipment, necessitating a weekend track possession, which added to the complications of planning and coordination of the works.
Complications included the diversion of utilities, reconstructing the roadway approaches, and re-profiling the river banks, where the need for anti-scour coir rolls became apparent after the river burst its banks due to heavy rains.
