Travel information alert:
Key information road users need to know during these works:
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 along the A27, which is mostly two lanes in each direction, during the closure. This is expected to be busy every day and drivers should be prepared for severe delays.
Drivers will be able to exit the M27 westbound at Junction 11 for Fareham and Gosport, and eastbound at Junction 9 for Whiteley and Park Gate. However, there will be no westbound entry to the M27 at Junction 11 for traffic heading towards Southampton or the A32 (Alton), and no eastbound entry at Junction 9 for traffic heading towards Portsmouth.
To reduce disruption and help keep traffic moving during the closure, a series of measures are in place or planned:
Advance inspections and repairs have been completed on the A27, plus there is a restriction on planned roadworks along the A27 during December 2025 and January 2026.
Advance signage across the wider road network, including the M25, M3, M4, A3, A27 and A34, to inform drivers early and support re-routing. Traffic levels will be monitored in real time, with updates displayed on electronic messaging signs.
Traffic signal reprogramming at key locations including M27 Junctions 9 and 11, and the A27, to help manage traffic flows during the closure.
