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 Northamptonshire County Council, Daventry District Council, Northampton Borough Council, South Northamptonshire Council and the West Northamptonshire Joint Planning Unit (who will all be replaced by the new West Northamptonshire Council from 1 April 2021) and 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
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 is designed to deliver the improvements at the A45 Queen Eleanor Interchange, the A45 Brackmills and Great Billing Interchanges as outlined in the Growth and Housing Fund bid. A review of the scheme is currently underway, as expected additional funding has not so far been forthcoming and forecast delivery costs exceed the estimated costs at the bid stage. 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.
