Highways England has formally unveiled the plan for seven smart motorway schemes, extra to the project currently taking place on the M62 and M60.
Two of the schemes on the M62 will link up with existing projects to create the biggest single stretch of smart motorway in the country, covering nearly 60 miles between the North West and Yorkshire.
Other major schemes planned for the region include bypasses on the A556, A585 and A57, new motorway junctions on the M55 and M56, and junction upgrades on the M6.
During this year alone, the Highway Agency has committed to resurfacing 130 miles of lanes on motorways and major A roads.
A further 40 miles of safety barriers will be installed, and 2,900 lighting columns will be upgraded.
Alan Shepherd, North West Regional Director at Highways England, said: We’re investing £1.5bn on improvements to the North West’s motorways and major A roads over the next five years, creating the biggest increase in capacity on the road network for 50 years.
“It’s vital that we continue to improve the existing road network as well, which is why we’re investing £90m this year alone on resurfacing, safety barriers and other maintenance projects.
The North West’s motorways and dual carriageways form the backbone for the region’s economy and this huge investment will ensure they remain healthy for many years to come.
Work on the North West’s first smart motorway began in July last year and affects a 17-mile stretch of the M60 and M62 in Greater Manchester. The £202m project is due to be completed in autumn 2017.
A new £233m smart motorway scheme along an 18-mile section of the M6 between junction 16 at Crewe and junction 19 at Knutsford is due to start this autumn.
Construction work on a £192m project to build a new A556 link road between the M56 near Bowdon and the M6 near Knutsford also began last year and is due to be completed by winter 2016/17.
Other major projects planned to start construction work before 2020 include new bypasses on the A585, to remove a major bottleneck on the main road to Fleetwood, and on the A57, to tackle congestion near Mottram and Hollingworth in Tameside.
Another scheme will improve access to the Port of Liverpool along the A5036, new motorway junctions will be created on the M56 (junction 11a) and M55 (junction 2) near Preston, and major upgrades will be made to junction 19 of the M6 near Knutsford and junction 22 near Newton-le-Willows.
North West smart motorway schemes
Two new smart motorway schemes on the M62 will run on a nine-mile section between junctions 10 at the M6 interchange near Warrington and junction 12 at the M60 interchange near Eccles, and on a 19-mile section between junction 20 at the A627(M) interchange near Rochdale and junction 25 near Brighouse, West Yorkshire (including seven miles in the North West).
A seven-mile stretch of smart motorway will be created on the opposite side of the M60 to the current scheme, between junction 24 at the M67 interchange near Denton and junction 4 at the M56 interchange near Cheadle.
A ten-mile section of the M6 between junction 21a at the M62 interchange near Warrington and junction 26 at the M58 interchange near Skelmersdale will also become a smart motorway, along with a four-mile section of the M56 between junctions 6 and 8 near Manchester Airport.
Finally, a six-mile stretch of smart motorway will be created on the M53 between junction 5 at Queensferry and junction 11 at the M56 interchange near Ellesmere Port.
