Video | 2,000t rail bridge slide

Timelapse footage has been released showing construction of a 2,000t rail bridge over the new M8 in Scotland.

Consortium the Scottish Roads Partnership oversaw the project, which represented the first major structure completion on the £500M M8-M73-M74 motorway improvements programme.

The consortium, which includes Ferrovial, Lagan and Amey, took possession of the rail line on 11 July and returned it to Network Rail as planned on 26 July.

The line had been closed over four weekends in April to allow installation of eight 2m-diameter piles as well as ground reinforcement works. The three-span steel bridge was then built adjacent to the existing railway.

A self-propelled modular transporter system was used to slide the three-span bridge into place this month.

Transport Scotland project sponsor Graeme Reid said: “The success of the bridge slide marks a significant milestone as part of the M8-M73-M74 motorway improvements project and is the first tangible improvement to the transport infrastructure.

“The timelapse gives a real sense of the challenges involved in delivering a project of this scale and encourages a greater understanding of civil engineering schemes and the benefits they can bring.”
