The M80 Stepps to Haggs motorway upgrade was completed on 26 August 2011.
The contract for the construction and the 30 year operation and maintenance period for the new motorway was awarded to Highway Management (Scotland) Ltd, and we are now in the Operation and Maintenance phase of the contract. The contract is valued at approximately £320 million.
The new motorway runs between Stepps and Haggs and has three distinct sections:
Throughout the length of the new motorway extensive environmental mitigation works and improvements have been provided, including:
- A road drainage system with ponds for the treatment of surface water run-off and accidental spills
- Noise reduction screening in the form of Fencing or earth bunds and the use of low noise road surfacing to reduce the traffic noise
- Landscape Planting, including planting around the drainage ponds
Stepps to Mollinsburn (the ‘Mollinsburn Bypass')
This section is approximately 8km of new road construction through agricultural land to the north of Muirhead, Moodiesburn and Chryston - linking with the existing M80 at Stepps and rejoining the route of the A80 east of Mollinsburn.
This bypass is enabling drivers to travel along a stretch of fit for purpose motorway, taking traffic off the local community roads.
The new motorway over this section provides:
- A dual two-lane carriageway (each, 7.3m wide), with hardshoulders (3.3m wide), a central reserve (4.0m wide) and roadside verges (a minimum of 1.5m wide)
- A new Interchange at Mollinsburn, with realigned side roads and three new overbridges
- New overbridges and underpasses at Hornshill Junction, Drumsack Road, Lindsaybeg Road, Strathkelvin Railway Path and Auchengeich Road
