Construction firm Keir has been awarded a £460m contract by National Highways to upgrade a “vital” route through the West Country.
The project will see work take place on a "missing link" along the A417 between Gloucester and Swindon, which helps to connect the Midlands and North of England to the South.
A three-mile stretch of single-lane carriageway on the A417 between the Brockworth bypass and Cowley roundabout in Gloucestershire could be replaced with four miles of new dual carriageway.
