Highways England aims to complete the scheme between junction 19 in Leicestershire and junction 16 in Northamptonshire by spring 2017.
Between now and 2020 Highways England will deliver £11bn of Government investment – that includes £3bn investment delivering 286 miles of smart motorways which will tackle congestion and improve journey times for drivers while maintaining safety.
This new scheme will see vital extra capacity created by the permanent conversion of the hard shoulder to a traffic lane.
Highways England project manager, Lee Wise said:
“This is an exciting scheme and once completed will bring big improvements with an additional lane for traffic. This will help hugely during times of congestion. We are committed to delivering this work differently with shorter lengths of traffic management wherever possible to help minimise disruption to drivers.
“I would however urge road users to please have patience and bear with us while we carry this work out as quickly as we can and to be extra vigilant and to extra take care when driving through the road works. The scheme when completed will be worth it and bring daily benefits to journeys for years to come.”
