Description of scheme
The A45 Northampton Growth Management Scheme (NGMS) is a number of junction improvements along the A45 trunk road between M1 Junction 15 and the Great Billing Interchange.
The NGMS is a joint project between ourselves, Daventry District Council, Highways England, Northampton Borough Council, South Northamptonshire Council and the West Northamptonshire Joint Planning Unit.
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
A map of where these junctions are located can be found below:
Drawings for the schemes that will be delivered first can be found below:
Plans for the other junctions will be shared as work progresses.
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 a combination of developer contributions (£1.797m) and the Highways England Growth and Housing Fund (£4.08m).
The funding secured so far will deliver the improvements at the A45 Queen Eleanor Interchange and the detailed design of the A45 Brackmills and Great Billing Interchanges in 2019 and 2020. It is anticipated that subject to further developer funding the A45 Brackmills and Great Billing Interchanges will be delivered between 2020 and 2021.
The remaining junctions will be improved as funding becomes available. No works will be undertaken at M1 Junction 15 until it is clear whether the junction is to be rebuilt for the proposed Northampton Gateway Strategic Rail Freight Interchange.
What happens next
Further details of the programme will be shared with local residents and businesses as they become available.
