    Upgrade now fully open

    The final 11-mile section of the M1 J13-16 upgrade has fully opened, with the national speed limit (70mph) restored.  

    We have been opening the 23-mile M1 upgrade in phases since late 2021. Completing this final section, at the northernmost section of the upgrade, means that we have now fully opened our upgrade on the M1 between Bedford, Milton Keynes and Northampton, creating an extra lane in each direction and adding technology to improve journeys and give drivers better information. 

    On motorways where the hard shoulder has been converted to a traffic lane, there is a whole system of inter-related features, working together to help keep traffic moving safely. They include:   

    Variable speed limits to help keep traffic moving, reducing frustrating stop-start traffic and making journeys quicker  

    Clearly signed and orange-coloured emergency areas set back from the road and with telephones linking directly to our control rooms   
    Detection systems to monitor traffic for changes in flows and speeds, including stopped vehicle detection to spot stopped vehicles and get help on the way more quickly  

    CCTV cameras that our operators are able to move and zoom to monitor and manage congestion and incidents, where notified. The system has the ability to see 100% of the carriageway 

    Signs and signals to provide better information and that can alert drivers to hazards ahead and display Red X signals to close lanes to other traffic when a stopped vehicle is identified 

    Enforcement cameras to deter the minority who break speed limits and ignore Red X signs   

    All this is overseen and joined up by our dedicated teams in the control rooms and on the road, who are here to help motorists 24 hours a day, 365 days a year.  

    Benefits 

    You can read more about the main features of smart motorways, and advice and guidance on safer driving and what to do in an emergency on our ‘Driving on motorways’ page.

    Phased opening of upgraded sections continues

    Today a 4.2-mile section of the M1 north of junction 14 at Newport Pagnell services (to Cattle Creep, near Hartwell) fully opened, with the 70mph national speed limit restored.

    On motorways where the hard shoulder has been converted to a traffic lane, there is a whole system of inter-related features, working together to help keep traffic moving safely. They include:

    • Variable speed limits to help keep traffic moving, reducing frustrating stop-start traffic and making journeys quicker
    • Clearly signed and orange-coloured emergency areas set back from the road and with telephones linking directly to our control rooms
    • Detection systems to monitor traffic for changes in flows and speeds, including stopped vehicle detection to spot stopped vehicles and get help on the way more quickly
    • CCTV cameras that our operators are able to move and zoom to monitor and manage congestion and incidents, where notified. The system has the ability to see 100% of the carriageway
    • Signs and signals to provide better information and that can alert drivers to hazards ahead and display Red X signals to close lanes to other traffic when a stopped vehicle is identified
    • Enforcement cameras to deter the minority who break speed limits and ignore Red X signs

    All this is overseen and joined up by our dedicated teams in the control rooms and on the road, who are here to help motorists 24 hours a day, 365 days a year.

    Next steps

    A further 4.5-mile section to junction 15 for Northampton is set to fully open in early 2023. Together, these make up the second section of the M1 upgrade.

    The third and final section of the upgrade, between junctions 15 and 16, began its phased opening last month, with four lanes in each direction at 60mph, and is expected to fully open by March 2023.

  • 15 November 2022

    More new lanes open to traffic

    The final stretch of our upgrade of the M1 started its phased opening from today.

    An extra, fourth lane is being made available over the next four nights to drivers in both directions on a 6.5-mile section of the motorway between junction 15 (Northampton) and junction 16 (the Upper Heyford Interchange). The whole section is due to have the additional lane open by 6am on Friday morning.

    Drivers travelling through this section will see a 60mph speed limit in place, temporary additional CCTV from the roadworks, and a free recovery service alongside the new permanent systems while final technology tests are carried out.

    This can only happen when there aren’t roadworks, and when drivers are able to use all lanes of the upgraded carriageway.

    The scheme is opening in sections; a fourth lane opened on the 9.4-mile stretch between Newport Pagnell Services and junction 15 (Northampton) in September. Both sections are expected to fully open, with the national speed limit restored, in the coming weeks.

    Drivers will now be able to use 46 new emergency areas if they need to stop in an emergency.

  • 22 September 2022

    New lanes open to traffic

    From today (Thursday 22 September), 4 lanes on the 9.4 mile stretch between Newport Pagnell Services and junction 15 (Northampton) are now available to traffic with a 60mph speed limit in both directions. 

    Once construction is complete, and before we fully open our motorway upgrades, new technology, which includes stopped vehicle detection, is tested. This means it is finely adjusted to suit the particular environment of the road where it has been installed. This can only happen when there are no roadworks, when drivers are able to use all four lanes of the upgraded carriageway.

    Safety measures which have been in place during the roadworks, such as the 60mph reduced speed limits, and a free recovery service for drivers who get into difficulty, continue. The temporary CCTV used during the roadworks also remains in place, working alongside the new permanent CCTV installed as part of the upgrade.

    Once testing shows the system is performing satisfactorily the maximum speed is increased to the national speed limit of 70mph.  We expect this to happen next month.

    The first section of the upgrade, a 7.6 mile stretch between junction 13 and Newport Pagnell services, opened earlier this year. We expect the final remaining link of the upgrade, the 6.5 mile section between junction 15 and junction 16 (Upper Heyford Interchange) to start its phased opening next month.

    This newly opened section includes 19 new emergency areas, where drivers can stop in an emergency. Once finished, the 23-mile upgrade will feature 46 new emergency areas, 8 more than originally planned.  

    We expect the scheme to be fully open, with the national speed limit restored, by March 2023. 

Project information

Overview

We converted the existing section of the M1 from Junction 13 at Milton Keynes South to Junction 16 at the Upper Heyford Interchange (A45 to Daventry, A4500 to Northampton) into a smart motorway. 

The project involved: 

  • converting the motorway between junctions 13 to 16 into four lanes of traffic with no hard shoulder
  • installing 46 emergency areas with emergency roadside telephones
  • new overhead gantries and electronic signs to show the variable speed limits and provide driver information  
  • new and replacement safety barriers in the central reservation and verge areas
  • CCTV cameras 
  • new noise barriers and partial replacement of the existing noise barrier 
  • planting trees and bushes to replace any removed during construction

The M1 is a key strategic road, carrying high volumes of heavy goods and other vehicles between London and the North.

This project aimed to help ease congestion and make journey times more reliable during busy periods on this stretch of motorway, and to:

  • reduce congestion and smooth the flow of traffic to improve travel times and make journeys more reliable between Bedfordshire, Milton Keynes and Northamptonshire.
  • support the economy within the region by providing much needed capacity on the motorway, reducing the cost of economic delay to commuters and business traffic
  • maximise motorway capacity while maintaining safety on motorways
  • minimise environmental impacts
