Highway, Bridges & StructuresProject Overview
The Old Flatts Bridge in Rotherham, UK carries the A630 Sheffield Parkway over a busy freight railway, acting as a vital arterial route between Rotherham, Sheffield and the nearby M1.
Works included: removing the existing curtain walls on the East and West sides, repairs to the diaphragm walls, and installing a new curtain wall.
The Challenge
Cairn Cross acted as the Specialist Subcontractor to restrengthen the A630 Rotherham Gateway road over rail bridge. An inspection found that the span between the abutment faces had shorted by 216mm in comparison to the as-built drawings. The bearings were beyond repair and needed replacement.
The Solution
Works were carried out to remove the existing curtain walls on the East and West of the bridge. Structural repairs were implemented to the existing concrete to increase longevity and strength. Further installation of steel sheet piling, concrete waterproofing, and jointing work enabled the structural reinforcing and worked to be carried out, whilst still allowing the vehicle traffic to use the bridge.
The Result
The Old Flatts Bridge continues to serve its purpose as a critical link between Rotherham, Sheffield, the M1 and nearby industrial and business parks. The works carried out by Cairn Cross help to defer more maintenance in the future to the bridge.
