During the year-long programme, engineers undertook essential steel strengthening and repair work before repainting the structure which carries services between Glasgow and Lanark, Larkhall and Motherwell.
Originally built in 1897 and widened in 1923, the improvements to the century-old structure have been delivered as part of a rolling programme of refurbishment and renewals designed to keep Scotland’s Railway safe and reliable.
Suzanne McKay, scheme project manager, said: “This significant investment not only improves the look of the structure but will help to extend its lifespan as work on this scale won’t be required for at least another 25 years.
“Some of our work had to be carried out at night when trains were not running and we are very grateful to the community for their understanding and patience during this time.”
Over the course of the project, approximately 300m of track was renewed and 1100m2 of waterproofing was installed. Grit blasting eliminated old paint and rust before engineers installed more than 10 tonnes of new steelwork to the bridge deck and parapets to strengthen the structure.
More than 12,000 hours were worked to complete the project, with around 225 tonnes of grit and more than 5,000 litres of paint used.
The project was delivered by Story Contracting on behalf of Network Rail.
