The hard shoulder will be opened to drivers to create extra lanes on motorways across the West Midlands as part of a £100 billion infrastructure spending programme.
Funding was confirmed for a series of improvements to motorways which include turning the hard shoulder into a new lane and using computer-controlled signs to inform motorists when it is safe to use.
The “managed motorway” proposals are part of a range of measures announced by Danny Alexander, the Chief Secretary to the Treasury, which include £70 billion on transport, £20 billion on schools and £7 billion on science and flood defences and £3 billion on housing.
According to the Government, infrastructure spending will boost the economy and “create jobs and prosperity”.
But Labour MPs claimed that the spending spree was an admission that years of cutbacks had been a mistake.
Jim Cunningham (Lab Coventry South) said: “We should obviously welcome any investment in the economy, but the Government should not have cut it in the first place.”
Funding was confirmed for managed motorway projects on the M1 junctions 13 to 19, passing by Rugby and Coventry, M6 junctions 2 to 4, by Coventry, and M6 junctions 13 to 15, further north in Staffordshire.
A similar scheme will also be introduced to the M5 from junctions 4a to 6, in Worcestershire, south of Birmingham. And the Government confirmed funding for a new link road connecting the M6 Toll to the M54, north of Wolverhampton.
Funding was also confirmed for the long-delayed Priority School Building Programme, and 22 schools in the West Midlands will be rebuilt by 2017.
More than £21 billion will be spent on new school buildings between 2015 and 2020, creating 275,000 new primary school places, 245,000 new secondary school places, 180 new free schools and 20 new university technical colleges.
A total of £6 billion will be spent on repairing roads – enough to fill in 19 million potholes, according to the Treasury – and £4 billion will be spent on resurfacing major national roads.
It also emerged that local enterprise partnerships will receive £5 billion in transport funding from 2016 and 2021, on top of the funding previously announced, which included £5 billion in EU structural funds and £12 billion over six years from the Treasury.
Another £600 million will be distributed directly to businesses through the Regional Growth Fund between 2015 and 2016, to create private sector jobs. This is on top of £2.4 billion allocated previously.
Mr Alexander said he was announcing “the most ambitious and long-lasting capital investment plans this country has ever known.”
