This major transport infrastructure project will support hundreds of skilled jobs in the hard pressed construction industry over the duration of the works and the long term economic benefits of the project will be realised by the greatly improved transport links provided. 

Key benefits include:

  • Improving journey times and journey time reliability through the Central Scotland motorway network
  • Helping promote sustainable economic growth by improving access to facilities and employment areas
  • Reducing emissions and tackling climate change by improving air quality and providing health improvement
  • Reducing the time to transport goods and services
  • Better connectivity between Glasgow and Edinburgh and to the south
  • Cutting congestion
  • Improving road safety through the reduction of traffic on local roads, reducing lane changing and helping prevent weaving between lanes.

About the project

The start of the procurement process was announced in December 2011, with the selection of bidders and the competitive dialogue and tendering continuing throughout 2013. The successful bidder, Scottish Roads Partnership (SRP), a consortium with a construction joint venture of Ferrovial Agroman and Lagan, was announced in February 2014. Read more about the background to this work including funding and support for the project.  

Traffic Management

As the Project develops, regular updates on the latest Traffic Management required to allow construction of the M8 M73 M74 Motorway Improvements Project to progress will be provided here.

Keeping communities informed

Work is now well underway across the M8 M73 M74 Improvements Project and given the scale of the site, construction will take place alongside some community boundaries.

Planning and managing the construction work is key to minimising any impact on local communities and will ensure the safety of those communities living in close proximity to the works.

Glasgow - Edinburgh Completing the M8

The upgrade of nearly seven miles of the existing A8 between Baillieston and Newhouse, which forms part of the M8 M73 M74 Motorway Improvements project, will result in a new motorway between Baillieston Interchange and Newhouse Junction. This new length of motorway completes the M8 motorway link between the cities of Glasgow and Edinburgh.

Raith Junction improvement works

Raith Junction is a roundabout linking the M74 motorway with the A725 Bellshill Bypass and East Kilbride Expressway. The improvements at Raith will provide substantial benefits across the whole of the Central Belt of Scotland.

Network upgrades

The network improvement works, which form an element of the M8 M73 M74 Motorway Improvements project, have been devised as a package of road and junction improvements to tackle both existing and anticipated congestion problems.
