A43 Northampton to Kettering improvements

The county council has outlined a policy to dual the A43 between the junction with the A45 and the A14 within Northamptonshire.

Description of scheme

The A43 between Northampton and Kettering suffers from congestion hotspots, journey time delay and road safety issues due to vehicles trying to overtake. Through its key strategy document, the Northamptonshire Arc, the county council has outlined a policy to dual the A43 all the way between the A45 and the A14. Due to the scale of the scheme this will be achieved in phases.

Improvements to the Round Spinney roundabout (phase 1a) have already been completed resulting in increased capacity at this junction and improved traffic flow.

Phase 1b, which will provide a new road between the Round Spinney and Moulton roundabouts bypassing the existing road, is currently awaiting confirmation of the Compulsory Purchase and Side Roads Orders below.  Subject to this happening, it is hoped to start construction later in 2018.

Phase 2, dualling of the section north of the Moulton roundabout to a new junction near Overstone Grange, has been completed.

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. The intention is to resubmit a bid at a future date.

Further phases will be needed to complete the dualling through to the A14 but have not yet been determined.

Compulsory Purchase Order and Sides Roads Order

The county council has made a Compulsory Purchase Order and submitted a Side Roads Order to the Secretary of State for Transport to authorise acquisition of land and make changes to the roads to enable the Phase 1b (Moulton Bypass) section of the road to be built.

Below are the notices which gave details on how to submit objections. Objections have been received and a Public Inquiry will need to be held unless the objections are withdrawn. Negotiations have taken place with the objectors and it is hoped that it will be possible to resolve the objections without the need for a Public Inquiry.   

The intention would be to start construction of phase 1b as soon as possible once these orders are confirmed.

Benefits of the scheme

Together, phases 1b and 2 will reduce congestion and journey time delay. The improved road network and traffic flows will support economic growth as the first part of a strategic link between Northampton and the A14.

The scheme is directly linked to enabling growth to the north of Northampton, including specifically the Overstone Leys development which comprises about 2,000 houses and ancillary development.

Route

The route will run north from the signalised A43 Round Spinney roundabout, crossing a small landscaped area before passing between the existing residential properties that front the A43 and the Round Spinney Industrial Estate. It then runs parallel with the existing A43 to the east of existing residential properties fronting the A43 before crossing The Avenue (which will be stopped up) and joining Overstone Road at a new roundabout junction replacing the existing roundabout to the north of Overstone Road. The dual carriageway will continue and will re-join the existing A43 approximately 300m north of the Overstone Road roundabout opposite the northern end of Park View. The dualling will continue to a new roundabout south of Overstone Grange which will, in time, give access to the northern part of the Overstone Leys development.

Public consultation

Early consultation with stakeholders including parish councils was undertaken in 2008/09 which established a broad consensus that dualling of the road between Round Spinney and the A14 was supported.

Consultation and examination hearings for the West Northamptonshire Joint Core Strategy highlighted the view of the local community that improvements to the A43, among other measures, are necessary to support the proposed development at Northampton North.

Planning permission for phases 1b and 2 was granted in August 2015. Further details are available on our Planning pages.

Scheme cost and how it will be funded

This scheme is funded by the Northamptonshire Growth Deal and supported by the South East Midlands Local Enterprise Partnership (SEMLEP).

The scheme is likely to cost in the region of £26 million.
