Temporary traffic management measures on an under-construction Northampton roundabout will remain in place over the Christmas period for “safety reasons”.

Major redevelopment works on the Queen Eleanor roundabout have been ongoing since March, after it was deemed “not fit for purpose”.

The works are expected to improve traffic flow and reduce congestion, by completely reconstructing the carriageway to meet “modern standards”.

At the start of the project, West Northamptonshire Council (WNC) and National Highways said works would be complete by Christmas this year. However, the target completion date has been pushed back to spring 2026 – “subject to weather conditions” - as the extension of the subway must undergo further construction.

Temporary traffic management measures will remain in place on the Queen Eleanor roundabout over Christmas, before work resumes in the New Year.

Also, the construction of the concrete cantilever parapet extension - a protective barrier projecting outward from the main structure - has been delayed, as it had to undergo a redesign.

A WNC spokesman said: “For safety reasons, temporary traffic management will remain in place throughout the Christmas and New Year period, including concrete protection barriers on Mere Way and London Road.

“Work is scheduled to recommence in early January 2026, with all remaining activities planned for completion in spring 2026.”

Follow-on activities in Mere Way and London Road will also include the installation of a new kerb line, creation of a grass verge, carriageway resurfacing, new road markings, final traffic signal installation and Vehicle Restraint Systems (VRS) for enhanced safety.

Councillor Richard Butler, Cabinet Member for Highways and Transport, said: “We know this work has been incredibly disruptive and we appreciate everyone’s patience and understanding as we work to complete these essential improvements.

“We’re expecting those who use this interchange to see noticeable improvements as a result of the extensive work currently taking place.”

Once the construction is complete, temporary traffic management will be removed from the roundabout and the interchange will revert to a fully signalised junction. WNC says this will “enhance safety for drivers and pedestrians” and increase lane capacity.

The west side of the roundabout (Mere Way and London Road) is currently undergoing night time closures, from 8pm until 6am. These closures continue until December 19. Diversion routes will be signposted on the A45.
