Forth Road Bridge

Client: Strainstall

Main Contractor: Amey

Duration: December 2015

The Forth Road Bridge is a suspension bridge spanning the Firth of Forth and connecting Edinburgh to Fife in Scotland. The bridge’s has a main span length of 1,006 metres and a total length of 2,512 metres. At the time of opening the Forth Road Bridge was the largest suspension bridge in the world outside of the USA. 

After steelwork defects were discovered during routine inspections, the bridge was closed to all traffic on 4th December 2015. Upon completion of emergency repair works, the bridge was re-opened to all traffic except from HGVs on 23rd December 2015.

R L Geotechnical Ltd. was called upon by Strainstall at short notice to assist with the urgent installation of strain gauges onto the repaired trusses over the Christmas period. We mobilised to site on 26th December and were able to help ensure that the installations did not slow over the Christmas break.

The bridge re-opened to all traffic on 20th February 2016.
