We are taking this opportunity of writing to inform you of the planned closure of the M27 over the Christmas 2025 period.
A full closure of the M27 between Junctions 9 and 11, is planned for Christmas 2025, and is expected to cause major disruption to the National Health Service (NHS) in Hampshire. While the Local Authority state the closure is timed for lower holiday traffic, significant delays on diversion routes are anticipated, impacting patient transport, staff commuting, and emergency services.
The closure is necessary for the installation of a new four-lane underpass at Junction 10, a complex "box slide" engineering technique that avoids many months of future lane restrictions.
Key points regarding the closure:
Dates: 8pm Wednesday, December 24, 2025, to 4am Sunday, January 4, 2026.
Location: M27 in both directions between Junctions 9 and 11.
Diversion: A signed diversion route will be in place along the A27.
Access: Drivers can exit at J9 eastbound and J11 westbound, but entry onto the M27 will be restricted at these junctions in specific directions.
For the latest updates and detailed travel advice, refer to the Hampshire County Council M27 J10 scheme website or National Highways information pages.
Mitigation and Advice
Plan Ahead: Road users, including practice staff and patients, are strongly advised to plan journeys in advance, consider alternative routes, and allow extra time for travel.
Diversion Routes: A signed diversion route will be in place along the A27, but drivers should not rely solely on satellite navigation systems, which may direct traffic onto unsuitable local roads.
Check for Updates: Regular updates and detailed travel advice are available on the Hampshire County Council website.
Consider Alternatives: Where appropriate, patients might be encouraged to use public transport (if available on the bank holidays/weekends) or consider if their journey to the Practice is strictly necessary, potentially using phone or online consultations if available.
The works are part of an improvement scheme for M27 Junction 10, aimed at creating a new "all-moves" junction to support the development of the Welborne Garden Village and avoid months of longer-term disruption.
