    October M1 road closures

    Upcoming road closures

    We need to close some junctions in order to progress our work. These closures are required for traffic sensors as part of our Motorway Incident Detection Automatic Signalling system. This detects the levels of traffic and provides real-time information to our regional control room staff who monitor the traffic conditions and safety. The data also automatically sets and adjusts the variable traffic speed limits shown on the motorway message signs to drivers. It keeps traffic moving smoothly, reduces congestion, makes journey times more reliable, and helps reduce accidents.

    The M1 will be closed on the following dates:

    M1 Northbound

    Date Duration Details
    Friday 22 October 10pm - 6am M1 junction 13 to 14 Lane 3 and 2 closed
    Saturday 23 October to Sunday 24 October   Newport Pagnell Services closed until 6am Sunday 24 October. 
    Monday 25 October   M1 junction 15 exit slip closed. Allow an extra 15 mins
    Wednesday 27 October   M1 junction 15 to 15a Lane 1 and 2 closed

    Thursday 28 October

    Progress report

    We have completed the surfacing of lanes 1 and 4, and landscaping between junctions 13 to 14, with the majority of vehicle restraint safety barrier also finished.

    The installation of drainage and communication ducting between Newport Pagnell and junction 16 is progressing well.

    We’re installing stopped vehicle technology on this stretch of the M1 as part of our upgrade. Stopped vehicle detection is a valuable extra safety measure on motorways without a hard shoulder. It can detect vehicles stopped in a live lane in a matter of seconds, helping to close traffic lanes and get help on the way sooner. 

    We expect the installation of stopped vehicle detection between junctions 13 to 14 to be complete during August 2021. Roadworks will remain in place during this time, for the safety of our workforce and the public.

    Upcoming work

    We’ve made good progress in our job to re-surface the carriageway between junctions 13 and 14 in preparation of this section of road being opened as an upgraded motorway in late March 2021.

    Seven new steel gantries have been installed which are used to show the electronic message signs and junction information signs once the smart motorway is open.

    Following on from the completion of our sheet piling work up to junction 15, we’re now continuing with the installation of many kilometres of drainage pipes and communications ducting.

    Next steps include:

    • completing the installation of sheet pile walls against the verge north of junction 15
    • installing cross-carriageway drainage ducting between junction 15 and 16
    • completing the remaining re-surfacing and refreshing road markings between junction 13 and 14
    • erection of steel overhead gantries to hold the message signs in the area north of junction 15

    We’re working hard so that we can open further sections of the new motorway layout throughout 2021 and during the first half of 2022.

    Upcoming work

    Between junction 15a and junction 16, we’ve made good progress in our job to complete the verge-retaining walls. And we’ve begun to remove the temporary vehicle barrier between junction 13 and junction 14. Once removed, lane 1 (the left-hand lane) will still be closed to vehicles by traffic cones. We will keep the cones in place until we complete the re-surfacing of the carriageway and change the lane markings for the new motorway layout. This section of road will then be completed and open as a smart motorway later in spring 2021.

    We’re working hard so that we can open further sections of the new motorway layout throughout 2021 and during the first half of 2022. This involves the installation of many kilometres of drainage pipes and CCTV and emergency telephone ducting, construction of bases for the overhead steel gantries which show the electronic message signs, and installation of all the new technology.

     What's next?
    • Re-surfacing and refreshing road markings between junction 13 and 14
    • Installing drainage and communication ducting between Newport Pagnell Services and junction 16
    • Erection of steel overhead gantries to hold the message signs in the area north of Newport Pagnell Services
    • Reinforcing the concrete extension of the Cattle Creep underpass between junction 14 and 15.
    • Installing sheet pile walls against the verge north of junction 15.

     

    M1 junction 13 to 16 progress

    In March 2021, we’ll have finished our work between junctions 13 to 14 of the M1

Project information

Overview

We’re converting 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 involves: 

  • converting the motorway between junctions 13 to 16 into four lanes of traffic with no hard shoulder 
  • installing 38 new (and two upgraded) 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

 

Covid-19

During the pandemic, we are following Government policy which is that construction activity should continue where it can be done safely. All our sites have strict safeguarding measures to prevent the spread of COVID-19 and none of our sites are open to the public. With traffic volumes on our roads still lower than usual, we are taking the opportunity to push ahead with our work before traffic levels return to normal. We plan our work carefully in order to minimise disruption to motorists.

Safety

During the current roadworks, there is no place for motorists to stop or leave the motorway other than the exit slip roads or motorway service areas. A free vehicle recovery service is offered for motorists who breakdown in our roadworks.

Always try to exit the motorway immediately if your vehicle is damaged or experiencing difficulties. If this is not possible and your vehicle stops in the nearside lane (lane 1) and you feel able to exit safely with any occupants, try to exit your vehicle via the nearside (left hand) door, and wait behind the safety barriers on the verge if it's safe to do so. In all cases, switch on your hazard warning lights.

 

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

This project will help ease congestion and make journey times more reliable during busy periods on this stretch of motorway. 

Our project aims to: 

  • reduce congestion and smooth the flow of traffic to improve travel times and make journeys more reliable between BedfordshireMilton 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 

Traffic management

While we're carrying out this work, there will be narrow lanes on the motorway and a reduced speed. During the day-time, we'll keep three lanes open in each direction. To carry out essential works, off-peak lane closures and overnight full carriageway closures will be necessary, for example, when we put new gantries into position and resurface the carriageway. Wherever possible, we'll keep this to a minimum. Night-time working hours will vary depending on traffic conditions.

During construction, there will be:

  • Three lanes open to traffic in each direction
  • Free breakdown recovery service along the extent of the scheme
  • 24-hour CCTV coverage to identify incidents and allow timely recovery
  • Planned diversion routes

Length of roadworks

We're carrying out this work in a way that will create the minimum of disruption to drivers using this busy stretch of the M1.

We'll be working in phases to reduce the extent of roadworks and the timescales for completing the scheme. 

Roadworks and traffic management

Safety is at the heart of what we do. Working close to machinery and live traffic brings hazards, so it’s important that our staff have regular rest breaks. If it appears that work is only taking place on one small section of the road, staff may be on their rest breaks. Alternatively, they may be moving steadily along the coned-off lane.

Reduced speed limits help keep all road users safe, not just road workers. Roadwork sites can be dangerous places. The driving environment around roadworks can be very different from normal. There may be changes to the normal standard of carriageway, such as lane restrictions or contra-flow running, as well as works vehicles entering or leaving the site. Excavations, vehicles and equipment pose additional risks and the safety of road users is always our primary consideration.

Roadworks during public holidays

Where possible, we'll remove traffic management during public holidays.

An environmental screening exercise at an early stage of the project indicated that it was considered unlikely there would be significant adverse effects resulting from the M1 junctions 13 to 16 smart motorway scheme. The key issues considered include:

  • air quality mitigation, in relation to housing and air quality management areas
  • surveys for protected species and habitats including bats, badgers dormouse and great crested newts
  • to minimise the loss of vegetative screening along the scheme and to design mitigation to reinforce screening for the future

Some sections of the existing noise barrier will be replaced with new sections of environmental barrier as they have reached the end of life. Additional noise barriers will also be delivered as part of the scheme design at a number of Noise Important Areas.
