15. Forth Road Bridge expansion joint replacement
Robert McCulloch

When the 1,006m-long Forth Road Suspension Bridge opened in 1964 it carried some of the largest expansion joints of their type anywhere in the world and, by the early part of this century, these needed replacement.

A replacement scheme was shelved temporarily once construction of the Queensferry Crossing was approved, given the disruption to bridge users that joint replacement works would have entailed. When the Queensferry opened, the reduced traffic on the Forth Road Bridge meant the scheme could be resurrected and even extended to include replacement of the footway joints as well as the comb and nosing joints on the approach viaducts and at the side towers.

This presentation will describe the procurement and construction process for the new joints, as designed by Atkins. Tenders were issued in 2017 for a works contract which was subsequently awarded to American Bridge international.

Works to replace the joints commenced in 2018, with Amey acting on behalf of Transport Scotland as part of a contract to operate and maintain the bridge. BEAR Scotland subsequently took over for the operation and maintenance of the bridge in August 2020.
