The county council outlined a policy to dual the A43 between the junction with the A45 and the A14. We have already improved the Round Spinney roundabout and constructed a section of dual carriageway north of Moulton. Construction work began in February 2019 on the Moulton Bypass section of the route and it was fully opened for traffic on 19 June 2020.
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) were completed in 2015, resulting in increased capacity at this junction and improved traffic flow.
Phase 2, dualling of the section north of the Moulton roundabout to a new junction near Overstone Grange, was opened to traffic in early 2018.
Phase 1b was fully opened for traffic in June 2020, providing 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 on our behalf by England’s Economic Heartland in August 2019, and we are now developing a Strategic Outline Business Case to support this submission, which should be submitted by the end of 2020.
Further phases will be needed to complete the dualling through to the A14 but have not yet been determined.
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 2,000 house Overstone Leys development and 1,500 house Roundhill Park development.
Phase 1b runs 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 the new roundabout junction which has already been constructed.

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
Side Roads Order
The Secretary of State has confirmed the Side Roads Order for Phase 1b as modified by him. The Side Roads Order provides the County Council with powers to improve and stop up highways, construct new highways, to stop up existing private means of access to premises and provide new means of access to premises.
As the confirmed Side Roads Order contains handwritten modifications in red ink, we have created a version incorporating those modifications, which can be read with assistive technology.
