Galliford Try will begin work on a £373M scheme to upgrade the M1 to a smart motorway next month.
Work will include upgrading junctions 13 to 16 to four lanes with no hard shoulder to increase capacity and adding 38 new emergency areas and roadside telephones to the road, which runs through Bedfordshire, Buckinghamshire and Northamptonshire.
The contract also includes the provision of new superspan gantries to support variable mandatory speed limits and driver information, and the hardening of the central reserve and installation of a rigid concrete barrier between junction 13 and 15 to prevent cars crossing over from opposite sides of the carriageway.
Highways England project sponsor Tabatha Bailey said: “This is vital work to improve journeys through a busy stretch of the M1 and once complete, will boost the local economy by increasing capacity and supporting future housing development.
“It will provide a continuous smart motorway from the M25 all the way to junction 19 at Catthorpe. This means that a key arterial route in England will offer increased capacity and more reliable journeys for the hundreds of thousands of people that use the M1 every day.
“To make journeys more reliable, motorists using that stretch of road will be given real-time traffic information using the latest technology which will allow them to plan more efficiently.”
Work will start on the scheme on 8 August and is expected to deliver £959M of benefits to the local area.
