Striking new images released by Highways England give a bird’s eye view of the new ‘half hamburger’ roundabout starting to emerge which will tackle congestion at a busy road junction in the East Midlands.

One year on since work started, the progress being made on the improvements at the A45/A6 Chowns Mill roundabout in Northamptonshire is clear in these new aerial pictures.

Highways England is investing £24 million to increase capacity at Chowns Mill which experiences severe congestion due to the amount of traffic on the A45 and A6, as well as local traffic accessing Higham Ferrers and Rushden. 

The improvements will see the junction redesigned in the half hamburger layout including a new link road connecting the A6 South and A5028 with the existing roundabout. All approaching roads will also be widened to provide extra lanes and to accommodate more vehicles.

Highways England Project Manager Dean Holloway said:

“Despite the challenges of the last year we have pushed ahead with work on these much-needed improvements. We know how important this scheme is for drivers, businesses and the local communities who have been enduring the severe congestion problems at the roundabout.

“The new layout will mean smoother, safer and more reliable journeys for drivers and we will build on the progress already made to deliver these improvements as soon as we can.”

Single and narrow lanes have been introduced during the work to keep roads open where possible.

However, to enable the next stage of the scheme to go ahead and ensure the safety of road workers, the roundabout will need to be closed to traffic for two consecutive weekends. This is to enable a new road surface to be laid on a number of sections.

Taking advantage of the lower traffic levels due to lockdown restrictions, the work can be carried out swiftly by fully closing the roundabout for two weekends rather than having a series of road closures over several weekends or nights.

The roundabout will be closed from 8pm Friday 19 February until 5am Monday 22 February. It will also be closed the following weekend from 8pm on Friday 26 February until 5am Monday 1 March.

For drivers on essential journeys, diversion routes agreed with the local authority will be clearly signposted.

Once the re-surfacing work is completed, drivers will benefit from smoother and quieter roads through the junction.
