Forth Road Bridge expansion joints to be replaced next month

Forth road bridge

Work to replace the main expansion joints on the Forth Road Bridge will begin next month.

American Bridge International has been appointed to carry out the works, with Forth Bridges operating company Amey managing and supervising the project on behalf of Transport Scotland.

Works are set to get underway on 12 November, nine years after they were originally scheduled.

The joints were originally due for replacement in 2009. However works were postponed until the completion of the  Queensferry Crossing to avoid disruption to traffic.

Failsafe devices were installed for safety, along with improved maintenance access to allow an enhanced regime of monitoring and inspection to be implemented until the joints could eventually be replaced.

The works are estimated to last 12 months and cost £5.9M, less than half the original £13.7M price tag set when originally tendered in 2008.

Traffic on the bridge will be restricted to a single lane in each direction for most of 2019 while work on the carriageways is in progress.

Amey account director for the Forth Bridges Unit Mark Arndt said: “The main expansion joints have exceeded their design life and are overdue for replacement, however we’ve been monitoring them closely over the years to ensure the continuing safety of bridge users and we’re now ready to replace them without any disruption to traffic.

“The new joints have been manufactured in Ayrshire and Sheffield, using a similar overall design to the originals, but with improved materials and enhanced details. The team has been planning and preparing for this project for a number of years and we’re looking forward to starting work on site.”
