Highways England is carrying out the £7 million scheme to improve capacity and journey times by widening the roundabout junction, upgrading the layout, approaches, signals and crossing facilities.
The scheme will also give the roundabout the capacity it needs for the future, supporting thousands of new homes and jobs in the area and an expected increase in traffic volumes.
Members of the public can meet the project team at an engagement event on Saturday 7 November to discuss the improvements.
An image of how the new roundabout will look has been created.
Kevin Harvey, project manager for Highways England, said:
As part of record government funding, this scheme will help boost the local economy and support up to 4,650 new homes in the area.
This is about improving the roundabout for everyone concerned, as well as better, more reliable journeys for our road users; we’ll also be making the junction safer and more accessible for pedestrians, cyclists and horse riders.
It will be great to see local people or anyone who uses this road regularly on Saturday, so we can hear people’s views and explain exactly what will be involved with this scheme and the impact the work might have.
The scheme will be carried out in two phases to minimise disruption as much as possible. Phase one will take place between January and summer 2016 with service providers undertaking advanced work and Highways England supervising.
Phase two, between summer 2016 and spring 2017, will see our appointed contractor carrying out the main work. This phase of work will be where we carry out the road widening, erection of retaining walls and installation of the signals equipment.
Due to the closeness of the roundabout to nearby homes, phase one is likely to be carried out during the daytime to avoid noise at night. Phase two will also be predominantly day working with narrow lanes working. Some night time working and closures will be required where necessary.
Highways England will announce further information about dates and traffic management nearer the commencement of the scheme. The scheme webpage will be regularly updated:
The engagement event is being held at Towcester Community Centre in Islington Road between 10am and 3pm.
