M27 Roadworks Near Completion as Full Capacity Set to Return

Long-running roadworks on the M27 are nearing completion, with National Highways confirming that all four lanes will reopen later this month.

The works, which have significantly affected journeys for an extended period, have been particularly noticeable between Junctions 5 and 7—linking Eastleigh and Hedge End—and extending towards the River Hamble.

According to National Highways, the scheme is due to conclude with the full reopening of the motorway by 6am on Tuesday, 21 April.

The project has involved resurfacing the carriageway, with a new asphalt layer installed over the original concrete base. Due to the increased depth of the new surface, additional upgrades have been required to safety barriers, drainage systems, structures and other roadside infrastructure.

While all lanes will reopen, a temporary 50mph speed restriction will remain in place to allow for final testing and checks. National Highways has indicated this will be lifted later in the spring.

Councillor Nick Adams-King, leader of Hampshire County Council, welcomed the progress, noting the reopening would ease pressure on commuters and restore normal traffic flow along the route.

Further works are continuing at Junction 10 as part of infrastructure delivery linked to the Welborne Garden Village development, with completion expected later this year.

The completion of the M27 scheme marks a significant milestone in improving journey reliability and long-term performance on a key section of the region’s motorway network.
