M27 road closure: information for patients and visitors

Hampshire County Council has announced that a full closure of the M27 between junctions 9 (Whiteley) and 11 (Fareham) will take place from 8pm on 24 December 2025 to 4am on Sunday 4 January 2026. This is so that a new dual carriageway underpass can be installed safely.

Signed diversions will be in place along the A27 during this time, which are expected to be particularly busy between 10am and 4pm each day. While the work has been planned to take place when traffic demand tends to be lower, delays are expected, so road users are being asked to plan their journey in advance, use public transport when possible and travel during less busy times.

We understand this may concern people with appointments over Christmas and the New Year, so wanted to share some helpful information ahead of time. NHS services including Urgent Treatment Centres, community pharmacy and GP Practices will continue to operate as normal and be available if you need them.

Appointments

If you have an appointment scheduled, please continue to attend. If we need to change anything, we will contact you directly, but are working to continue as many appointments as possible.

We know that roads may be busier around the hospital as people use different routes due to the road closure, so please plan before your journey and consider the best way for you to get to your appointment. We would also encourage you to check before setting off and consider using public transport where appropriate.

Urgent Treatment Centres

Urgent Treatment Centres remain open 365 days a year and will continue to be open during these road closures. Information on local Urgent Treatment Centres can be found below, so if you need their help, please check which is the most appropriate location for you to visit before leaving home:
