The northwest will see seven new Smart Motorway projects as part of a £1.5 billion road improvement plan by Highways England.
The government-owned company, which took over responsibility for England’s motorways and major A roads earlier this year, set out its five-year plan for the region this week.
Work will start on the seven new smart motorway projects by 2020, in addition to the project currently taking place on the M62 and M60, which is aimed at cutting congestion and improving journey times for drivers.
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.
And during 2015/16 alone, 130 miles of lanes on motorways and major A roads will be resurfaced, 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.
“That includes nearly 80 miles of smart motorway where the hard shoulder will be converted into extra lanes and variable speed limits will be used to keep traffic moving. New bypasses and new and improved motorway junctions will also all help to tackle congestion, benefitting both businesses and local residents.
“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.”
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.
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.
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 10-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.
