M1 junction 13 to junction 16: smart motorway
We’re improving the 23-mile section of the M1 between junctions 13 and 16 by upgrading it to an All-Lane Running (ALR) smart motorway to support economic growth and ease congestion in the area.
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 an All-Lane Running (ALR) 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 support Variable Mandatory 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 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 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
M1 junctions 13 to 16 smart motorway - variable mandatory speed limits - 26 March 2018 to 23 April 2018
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. This means that drivers will not experience 38km of roadworks during construction.
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.
