This project involved the construction of 18 km of dual two/three lane motorway with associated slip roads and infrastructure from Stepps in North Lanarkshire to Haggs in Falkirk, Scottland. 8 km of the project was an offline construction of a three lane motorway, with 10 km of online works consisting of widening the existing A80 from 2 lanes to 3 lanes of motorway standard carriageway. There were 63 structures (either new build or modifications to existing) on the project and seven interchanges and junctions including one interchange of the M74 with the M80.
Before the project was undertaken, the section of road between Stepps and Haggs was an all-purpose dual carriageway and was the only non-motorway section of the A80 between Glasgow and the end of the M80 at Dunblane. During peak hours, the road had suffered heavy congestion, delays and a poor level of service.
Traffic availability was achieved in August 2011 and the scheme now provides a significant reduction in congestion for road users, improved journey times and greater reliability. In addition, the risk of accidents was reduced and accessibility to freight deliveries improved. This is the second largest road project ever to be undertaken in Scotland.
