The M74 completion project passes through south east Glasgow and comprises eight kilometres of dual three-lane motorway.
Funded by Transport Scotland, Glasgow City Council, South Lanarkshire Council and Renfrewshire Council, the scheme completes a missing link in the west of Scotland’s motorway network, linking the existing M74 to the M8 motorway and providing an alternative strategic route across Glasgow, bringing significant benefits to transport links.
The £445 million main construction contract was delivered by Interlink M74JV, a joint venture between Morgan Sindall, Balfour Beatty, Morrison Construction, and Sir Robert McAlpine.
The project features four new grade-separated junctions, associated connecting roads and slip roads, and 13 major bridges and viaducts. The largest of these, the 750 metre Port Eglinton Viaduct, has 12 spans and stretches across several local roads and 12 sets of railway tracks, including the West Coast Main Line. Part of the viaduct was push-launched into position over the main approach route to Glasgow Central station.
The successful delivery of the project has been recognised by several award wins commending safety, sustainability and effective partnerships. This complex scheme was delivered eight months early and £20 million below budget as a testament to successful collaborative working.
During construction, the project directly supported up to 900 jobs within the construction industry, with 70 per cent of those employed being from the immediate area.
Extensive landscape planting was undertaken alongside the motorway, including more than 80,000 trees and shrubs and over 205,000 native ground cover plants, to soften the effect of the new motorway, enhance biodiversity and provide habitats for native species.
Extensive measures were implemented to treat contaminated land below the motorway, including capping of contamination, and sealing existing culverts and drains passing below to prevent contaminated groundwater passing into watercourses.
In total 86,000 cubic metres of contaminated material has been treated for re-use below the motorway. Extensive use has been made of recycling during construction with approximately 500,000 tonnes of crushed demolition material from a variety of local sources incorporated into the new embankments. This policy saved more than 3,500 tonnes of CO2 and reduced the requirement for imported stone.

The judging panel felt the M74 – Glasgow project stood out because of its scale, importance and the way the clients and providers worked together to deliver such a complex, and at times, controversial project in an exemplary fashion. The project delivered benefits for the wider community and local employment for the area”Chartered Institute of Highways and Transportation judging panel
