During the Autumn/Winter, the following traffic management and road closures will be taking place.

Please be aware that these closure dates may change:

M1 Junction 15a Temporary Traffic Measures and Closures

The programme of works on M1 J15a, to improve the junction and provide valuable, long term additional capacity that will help reduce congestion in the future, started during week commencing 1st May 2023.

The works, which are expected to take up to 28 weeks, will involve the widening of the junction to the latest standards and the installation of new traffic signals, along with new drainage, lighting, signage and upgrade to the existing pavement.

Temporary Traffic Management will include full lane closures with vehicles using J15a running in a single lane for most of the works. There will also be four, weekend closures and two weeks of overnight closures which will mostly occur during the later stages of the programme.

The works will be completed with traditional construction methods involving a substantial amount of excavation. Traffic Management needs to be in place for the safety of the public and workforce whilst construction is ongoing. The Traffic Management measures have been agreed with National Highways and West Northamptonshire Council. Throughout the construction period, the junction will be open for over 95% of time during the day and 90% at night.

We would like to reassure you that together with our contractors we will work to ensure any disruption to local residents and business is kept to the minimum practically possible.
