M8 / M73 / M74 Motorway Improvements

Completed Projects

We have upgraded this vital section of Scotlandís busiest motorway between Edinburgh and Glasgow, now connected by uninterrupted motorway for the first time in history. This link provides over 100,000 of Scotlandís daily travelling public with reliable journey times and improved safety. We have generated employment opportunities by creating over 1,000 construction jobs over the three-year contract, with 70% recruited locally.

Project Description/Scope/Context

The project is being delivered under a PPP arrangement by Scottish Roads Partnership (SRP), a consortium featuring Ferrovial Agroman sister companies, Cintra and Amey. We are leading the delivery of design and construction works on behalf of SRP, with Amey as lead designer.

The project scope comprises the design and build of a new 15km stretch of the M8 motorway between Ballieston and Newhouse, upgrading the Raith Interchange and widening 10km of existing motorway, managed across three geographical areas. The works also involve 18 new bridges, including the 2,000tn Braehead Rail Bridge which was executed in a 16-day rail possession.

Collaboration has been instrumental to the project, between contractors, designers and client, extending to wider stakeholders, including Network Rail. We are working with Transport Scotland, utilities providers, local authorities and key stakeholders, using Building Information Modelling (BIM) to integrate design, build and maintenance. This creates long-term operational solutions, such as the upgraded Raith Interchange, where the use of BIM has accelerated traffic management planning and temporary works, compared to conventional design methods.

For the first time ever, Glasgow and Edinburgh are now fully connected with a motorway, reducing travel times by up to 20 minutes at peak periods.

ADDED VALUE:

  • Installation of the 2,000tn Braehead Rail Bridge in a 16-day possession, an example of rigorous planning and effective collaboration
  • Design optimisation from an overpass to a junction at Chapelhall, reducing virgin earth import by 500,000m3 and off-site materials requirement by 300,000m3
  • BIM strategy fully integrated throughout design and delivery and into operations
  • Intelligent, whole-life approach to design and delivery e.g. using a pavement with a design life of 40 years for minimal intervention and reduced risk
  • Design optimisation to reduce temporary dewatering at Raith Junction during construction – reducing costs and creating environmental enhancements
  • Reduced 180,000 on-line lorry journeys through off-line haulage

"The new M8 will be a major milestone in what is a massive transport infrastructure project and I’m pleased to say the phased opening will start five days ahead of schedule. We are now close to seeing the culmination of three years of construction works and half a billion pounds worth of investment to improve this vital link between Scotland’s biggest cities. This investment will make a tangible difference to our economy, improving business links and connectivity, as well as reducing journey times for road users who rely on this route for part of their daily commutes.”
