Partly off-line upgrade of the existing dual two-lane A8 route to motorway standard, providing some new dual-three lane sections. Much of the route will have parallel A8 and M8 dual carriageways.
New junctions will be provided on the parallel road at Shawhead, Eurocentral and Chapelhall; substantial junction improvements will be carried out at Ballieston and Newhouse.
This scheme will complete the M8 between Glasgow and Edinburgh, which has been unfinished for many years, and will close one of the most obvious remaining gaps in the Scottish motorway network.
