The Project
The A74 between Carlisle to Guards Mill was the last "missing link" in the motorway network between London and Glasgow. This dual carriageway section of trunk road had several minor road junctions and therefore mixed relatively low-speed local traffic with high-speed trunk road traffic. It had a poor accident record and caused driver frustration, resulting in heavy goods vehicles using the outside lane of each carriageway. The upgrade of this section to motorway standard is predicted to bring the following benefits to road users:
- a reduction in the number of accidents on the route;
- the provision of more carriageway space for emergency services attending accidents;
- the provision of more carriageway space to enable traffic flows to be maintained following an accident;
- a reduction in driver frustration;
- an improvement in accessibility for users; and
- the provision of more predictable journey times.
The needs of local traffic and non-motorway users are catered for with the new adjacent all-purpose road (APR) along the full length of the Scheme.
On 5th December 2008 the M6 Extension Carlisle to Guards Mill was officially opened by Transport Minister Andrew Adonis. This date also marked the 50 year anniversary since the opening of the Preston Bypass, the UK's first stretch of motorway and now part of the M6.
