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 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.
Scheme cost and how it will be funded
The scheme will cost between £25m and £40m depending on whether it is built as a single or dual carriageway, and the extent to which earthwork material can be sourced from the adjoining Dallington Grange development site.
It is anticipated that the road will be funded by a combination of 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.
Outline business case
In order to gain access to government funding we have to prepare a business case in accordance with the Department for Transport's guidance on
transport business cases. The outline business case has to be submitted to the South East Midlands Local Enterprise Partnership (SEMLEP) who will determine whether our scheme is a good use of public funding.
The outline business case was submitted to SEMLEP in March 2019. The document can be viewed below:
A full business case will be submitted to SEMLEP later in the year.
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 has already been granted by Northampton Borough Council.
We have submitted a planning application for the section of the road we will build to the County Council’s planning service. You can view and comment on the application on our
planning applications webpage.
Following the consultation closing, the County Council’s Development Control Committee will be responsible for determining the planning application.
What happens next?
Work will continue to design the new road and gain the necessary powers and funding before construction can commence. Subject to planning permission and land acquisition, construction is planned to start in Spring 2020, with the road opening at the beginning of 2022.
Consultation on the Northampton Northern Orbital Route and Northampton North-West Relief Road closed on 4 August 2017.

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.
