These measures are in the interests of road safety while contractors undertake maintenance and renewal work of a cyclical nature and M25, M3 and A3 project works.

The duration of each closure will vary depending on the nature of the maintenance work being undertaken on each occasion. The programme of works will start on or after 2nd January 2025.

Overnight closures taking place on the M3 between Kitsmead Lane and Junction 14, and the A3 between Ockham and A3(M) Junction 1 will be in operation between 21:00 and 06:00 (maximum period).

The overnight closures on the M25, M3 between Junction 1 and Kitsmead Lane and the A3 between Hook Interchange and Ockham Interchange will be in operation between (maximum period) : 

Monday – Thursdays             22:00 – 05:30
Fridays                                  23:00 – 06:00

Sundays                               22:30 – 05:30

Planned maintenance work will be scheduled to avoid disruption during known peak periods, although essential maintenance may be necessary during these periods to prevent the need for emergency works. Please see National Highways website for specific details on any upcoming closures.

The Order will come into force on 2nd January 2025 and remain in force until 24th December 2025.

Traffic affected by the closures will be diverted via other junctions of the M25, M3 and A3, or by using the M20, M26, M27, A2, A20, A22, A23, A24, A25, A27, A30, A31, A32, A34, A217, A223, A224, A230, A240, A243, A244, A245, A246, A247, A287, A303, A308, A311, A312, A317, A320, A331, A322, A325, A327, A2025, A3008, A3044, A3090, A3100, A3113, B382, B2039, B2070, B2171, B2215, B3000, B3002, B3004, B3006, B3040, B3041, B3049, B3335, B3349, B3420, Bridge Road, Chillbrook Road, Downside Bridge Road, Downside Road, Forest Road, Horsley Road and Old Lane. 

The environmental weight limit on the A3008 (Hampton High Street) will be suspended to allow its use as a diversion. The diversion routes listed above are the agreed routes, but these may change depending on local conditions.

The diversion in operation will vary according to the closure in force. 

The temporary closures, hard shoulder and HGV outside lane running and diversion routes will be clearly indicated by traffic signs when they are in operation during the works period.
