Major highways projects
Major road projects in West Northamptonshire.
This work is being delivered as part of the Active Travel Fund.
You can view the updates to Phase 1 of the scheme in the document below.
Description of the scheme
High Speed Two (HS2) is a high speed railway which will connect major cities in Britain. A dedicated high speed rail service between London and the West Midlands is expected to open between 2029 and 2033.
The A361 is the approved route for construction traffic to access one of the main construction sites in Northamptonshire. It is located just to the north of Chipping Warden on the former airfield.
Stage one of the Relief Road extends from the A361 just north of Hogg End to a point north of Long Barrow. It was opened to traffic in June 2021, ahead of the main construction compound being fully operational.
Stage two will see the connection to the A361 altered to suit the permanent road layout. This will commence once HS2 Ltd have built the cut and cover tunnel for the new railway.
The approved plans for the Relief Road can be viewed on the Chipping Warden Parish Council website.
Benefits of the scheme
The Relief Road removes the need for traffic to travel via the village centre. This will reduce the number of vehicles in the centre of Chipping Warden, improve air quality, noise levels and road safety.
The Relief Road is a permanent feature so the village will continue to benefit once High Speed Two is completed.
Scheme cost and how it will be funded
High Speed Two Limited contractors designed and built the Relief Road. We made a £2 million contribution towards the cost of the scheme.
Public consultation
We undertook public consultation on possible routes in summer 2014. Strong support for a relief road to the west of Chipping Warden was received. High Speed Two Limited undertook public consultation as part of Additional Provision 2 in July 2015.
Further information
Further information on the High Speed Two project through Northamptonshire is available on the HS2 website.
The opportunity of delivering a bypass around Farthinghoe has been studied over many years with significant investment provided in developing a business case for funding. That business case shows the economic case for such a scheme is low and therefore funding from government for such a scheme is highly unlikely.
As a Council we have always acknowledged that as well as the number of vehicles going through the village, the pinch point where large vehicles have collided on a number of occasions does need to be resolved.
Work is continuing which will identify a preferred option for a mitigation scheme, and depending on what this is, it's expected costs and funding sources will determine whether it is deliverable by 2030.
This page will be updated as the scheme progresses.
Improvements to the Round Spinney roundabout (phase 1a) were completed in 2015. These resulted in increased capacity at this junction and improved traffic flow.
Phase 2 was a dualling of the section north of the Moulton roundabout to a new junction near Overstone Grange. This was opened to traffic in early 2018.
Phase 1b was fully opened for traffic in June 2020. This provided a new road between the Round Spinney and Moulton roundabouts bypassing the existing road.
Phase 3 is intended to extend the dualling to the Holcot and Sywell roundabout. A bid for Government funding towards this phase was submitted in 2016 but was not successful.
A bid for Major Road Network funding to construct this section was submitted in August 2019. We are now developing a Strategic Outline Business Case to support this submission.
A bid for Major Road Network funding to construct this section was submitted in August 2019 and a Strategic Outline Business Case has been submitted to support this. As at the start of 2025 we are still awaiting a decision on this from the Department for Transport, which will enable further work on the scheme design and business case to proceed.
Public consultation
Consultation and examination hearings for the West Northamptonshire Joint Core Strategy highlighted the view of the local community. Improvements to the A43, among other measures, are necessary to support the proposed development at Northampton North.
Scheme cost and funding
Phase 2 was constructed within its budget of £9.25m. It was comprised of:
- £6.5m of government funding secured through the South East Midlands Local Enterprise Partnership (SEMLEP) and
- £2.75m of Section 106 funding from the Overstone Leys development
Phase 1b was constructed within its budget of £17.5m. This included:
- £7.9m of government funding through the SEMLEP Local Growth Deal, and
- £4.1m of Section 106 funding
Phase 3 will cost in excess of £23m.
This section will be updated as the scheme progresses.
The NGMS is a joint project between us and National Highways (formerly Highways England).
We are project managing the scheme and funding on behalf of all the project partners. In total, seven junctions will be improved:
- M1 Junction 15
- A45 Wootton Interchange
- A45 Queen Eleanor Interchange
- A45 Brackmills Interchange
- A45 Barnes Meadow Interchange
- A45 Lumbertubs interchange
- A45 Great Billing interchange
Since the Cabinet’s decision in 2019, design activities have progressed for the future improvements on the A45 Northampton Growth Management Scheme (NGMS). A phased delivery has been considered in partnership with National Highways to initially focus on A45 Queen Eleanor and A45 Brackmills interchanges.
The remaining junctions will be improved as funding becomes available.
Details of the location of these junctions and scheme designs are available on request by email to [email protected]
Benefits of the scheme
The scheme will increase capacity, reduce congestion and facilitate housing growth along the A45 between M1 Junction 15 and the Great Billing Interchange.
Scheme cost and how it will be funded
Improvements to all seven junctions will cost more than £12m. A total of £5.877m has been secured so far from:
- developer contributions (£1.797m), and
- the Highways England Growth and Housing Fund (£4.08m)
The funding secured so far is designed to deliver improvements at the A45 Queen Eleanor Interchange, A45 Brackmills and Great Billing Interchanges. A review of the scheme is currently underway. A decision on how the scheme is to proceed is expected later in 2021.
The remaining junctions will be improved as funding becomes available.
What happens next
Further details of the programme will be shared with local residents and businesses as they become available.
Northamptonshire County Council consulted in 2017 on a new road linking the A5199 and Northampton North West Relief Road between Kingsthorpe and Chapel Brampton with the A43 north of Moulton. The scheme was expected to be funded by a combination of government and developer funding.
The case for and nature of any Northern Orbital Highway infrastructure will in part be dependent on the scale and location of development located in the new Local Plan. At the present time the need, nature and deliverability of the scheme is not sufficiently well defined and further study is required. This further study will include the evidence base for the new Local Plan which will benefit from the Council’s new Strategic Traffic Model.
This page will be updated as the scheme progresses.
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 south of the railway line will be constructed by the developers of Dallington Grange.
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.
Benefits of the scheme
The Northampton North-West Relief Road will reduce congestion in the North-West of Northampton. It will be providing a new crossing of the river valley.
The new road will also improve access to the motorway and other strategic roads. These include Moulton Park, Round Spinney and Lodge Farm Industrial Estates.
How the scheme will be funded
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 SEMLEP Local Growth Deal.
West Northamptonshire Council have committed up to £4.2m towards the scheme. Developers’ contributions of at least £15m have been identified towards the scheme.
Current Scheme Status
Work has now officially commenced on the relief road, with work due for completion in Summer 2024.
