Northampton North-West Relief Road

​The Northampton North-West Relief Road will link the A428 Harlestone Road with the A5199 Welford Road and serve the housing growth that is proposed to the west and north of Northampton. It will also help address existing congestion by providing another crossing of the river valley.

Description of scheme

The Northampton North-West Relief Road will link the A428 Harlestone Road with the A5199 Welford Road. The section from the A428 to just south of the railway line will be constructed by the developers of Dallington Grange, and indeed the first part of this section has already been constructed as part of the Harlestone Manor development. We will be responsible for building the section of road across the railway line connecting the developer's road to the A5199 Welford Road.

Following consultation in 2017, the Northamptonshire County Council cabinet meeting in October 2018 agreed a preferred route for the scheme.

Benefits of the scheme

The Northampton North-West Relief Road will reduce congestion in the north-west of Northampton, by providing a new crossing of the river valley.

The new road will also improve access to the motorway and other strategic roads from industry at Moulton Park, Round Spinney and Lodge Farm Industrial Estates.

How will the Scheme be funded?

It is anticipated that the road will be funded by a combination of central government, local government and developer funding.

Government funding of £7.93m has been allocated from the South East Midlands Local Enterprise Partnership Local Growth Deal.

Northampton Borough Council has committed up to £4.2m towards the scheme.

Developer contributions of at least £15m have been identified towards the scheme.

Full business case

A detailed business case for the Government funding was developed in accordance with the Department for Transport's guidance on transport business cases. and was submitted to the South East Midlands Local Enterprise Partnership in January 2020. Given the delay to the delivery programme a revised business case was considered necessary and this was submitted to SEMLEP in April 2021. SEMLEP are now reviewing the revised business case to determine whether they will continue to support the project financially. The Project continues to represent very high value for money when measured in accordance with government guidance.

The April 2021 revised business case be viewed below:

An accessible version of the full business case will be available within 4 weeks.

To request a copy of the appendices which support the business case please telephone 01604 883400.

Information events 

Public information events were held on 11 and 15 June 2019 to give people a chance to see how plans for the scheme had developed. The information boards from the public information events can be viewed below:


Planning permission for the section of the road within the Dallington Grange development was granted by Northampton Borough Council.

A detailed planning application for the section of the road the Council will build was submitted to the County Council's planning team and planning consent was granted by the Authority's Development Control Committee on 22nd September 2020 subject to a number of conditions being met before, during and after construction to ensure that the project is delivered responsibly in terms of its impact on local heritage assets, the environment and residents. View the report to the Development control committee, Site location and red line boundary plan, general arrangement plan and the landscape general arrangement plan:

What happens next?

Responsibility for the delivery of the project will pass from Northamptonshire County Council to the new West Northamptonshire Council in April 2021 and this is a significant commitment for the new Council. The final approvals have therefore been deferred until the West Northamptonshire Council Cabinet can meet to consider the scheme following the local elections planned for May 2021. Works will not start on site until approval has been granted. The scheme remains an important project to support growth in the local area however and whilst design work is effectively complete, work continues to secure the necessary land and ensure that all the necessary planning obligations are met to enable construction works to start as soon as possible.

Further information

Consultation on the Northampton Northern Orbital Route and Northampton North-West Relief Road closed on 4 August 2017.

The exhibition boards for the 2017 consultation, which provide further information about both the North West Relief Road and Northern Orbital route, including environmental constraints plans and projected traffic flows can be viewed below:

The proposals for the North West Relief Road were reviewed through a feasibility study in 2012 produced as part of the evidence base for the West Northamptonshire Joint Core Strategy. The study demonstrated that there are no major constraints to creating a road connecting the A428 Harlestone Road to the A5199 Welford Road. The options looked at in this work have been superseded by the 2017 consultation.
