Dates confirmed for M27 J9-J11 Closure over Christmas-New Year Period

A full closure of the M27 in both directions between Junctions 9 (Whiteley) and 11 (Fareham), scheduled from 8pm on 24 December 2025 to 4am on Sunday 4 January 2026

Key information road users need to know during the closure period:

• The M27 will be closed completely, in both directions, between Junctions 9 (Whiteley) and 11 (Fareham), from 8pm, 24 December 2025 to 4am on Sunday 4 January 2026.
• There will be a signed diversion route in place along the A27, which is mostly two lanes in each direction, during the closure. This route is expected to be busy, particularly between 10am and 4pm every day when drivers should be prepared for extended delays. Road users should aim to plan their journey in advance and consider alternatives including public transport, travelling during less busy times, using different routes, or considering if their journey is really necessary.
