A509 Isham Bypass

The A509 Isham Bypass has been developed to address existing traffic issues in Isham and to accommodate the anticipated traffic growth in the coming years.

Description of scheme

The bypass will commence at the A14 Pytchley Road roundabout (A14 Junction 9) and run in a southerly direction, west of the village of Isham, and re-join the A509 Kettering Road midway between Hill Top and Great Harrowden.

There will be two roundabout junctions:

  • at a junction with the existing A509 Kettering Road, south of the A14 Pytchley roundabout
  • at a junction with the B574 Hill Top Road

The A509 is an important primary route in Northamptonshire providing a north / south link between the A14 and A45 trunk roads, serving Kettering and Wellingborough and destinations towards the southwest.

Benefits of the scheme

The A509 Isham Bypass will improve transport links between Kettering and Wellingborough, helping to meet the needs of growth in the two towns, and also improve access from Wellingborough to the A14, while relieving some through traffic.

Public consultation

Consultation on the scheme with stakeholders and the public started in November 2001. Following further refinement, a preferred route was agreed by the Northamptonshire County Council Cabinet in May 2003.

Update January 2021

A bid for Major Road Network funding was submitted to the Department for Transport in March 2020 and they invited us to progress this by submitting a Strategic Outline Business Case, which was done in December 2020. The Borough Council of Wellingborough is providing funding to progress the necessary work on the scheme.

The first section of the road, south of the A14, will be constructed as part of the DB Symmetry development adjacent to A14 junction 9. This will require a repositioning of the roundabout junction of the bypass with the existing A509 Kettering Road. A modification of the current planning permission will be needed.

Further information will be published here as it becomes available.
