M23 Motorway & A23 Trunk Road, Surrey & West Sussex - Temporary Traffic Restrictions

M23 MOTORWAY AND A23 TRUNK ROAD

TEMPORARY TRAFFIC RESTRICTIONS

Notice is hereby given that National Highways intends to make Orders on the M23 Motorway and A23 Trunk Road in the Counties of Surrey and West Sussex, under Sections 14(1)(a), 14(1) (c) and 14(7) of the Road Traffic Regulation Act 1984 because works are proposed to be executed on, or in the vicinity of, the road. The effect of the Orders in this area would be, in phases, to: -

1.   authorise the overnight closure of –

(a)  both carriageways of the M23 between Junction 8 and Junction 11;

(b)  both carriageways of the M23 Gatwick Spur at Junction 9;

(c)  all slip and link roads leading to and from the lengths of carriageway described in 1 . (a) above;

(d)  the circulatory system at Junction 9 and Junction 11;

(e)  the hard shoulder adjacent to the lengths of carriageway and slip and link roads in 1. (a) to (c) above;

(f)  any emergency refuge area adjacent to the lengths of carriageway in 1. (a) above;

(g)  both carriageways of Airport Way between North Terminal Roundabout and South Terminal Roundabout at Gatwick Airport;

(h)  the slip roads leading to and from the northbound carriageway of the local A23 to and from North Terminal roundabout at Gatwick Airport; and

(i)   the link road connecting from the southbound carriageway of the local A23 to the eastbound carriageway of Airport Way at Gatwick Airport.

2.   authorise the overnight use of the hard shoulder adjacent to the lengths of carriageway and slip roads described in 1. above.

3.   permit HGVs in the outside lane of the lengths of carriageway described in 1. (a) above, during inside-lane closures.

These measures would be in the interests of road safety while contractors undertake maintenance and renewal work of a cyclical nature, and M23 and A23 project works.

The duration of each closure would vary depending on the nature of the maintenance work being undertaken on each occasion. The programme of works would start on or after 2nd January 2026. Overnight closures would be in operation between 20:00 and 06:00 (maximum period).

Planned maintenance work would 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 would come into force on  2nd January 2026 and remain in force until  24th December 2026.

Traffic affected by the closures would be diverted via other junctions of the M23, or by using the M25, A22, A23, A25, A264, A2011, A2220 and the B2036. The diversion in operation would vary according to the closure in force, and the diversion routes listed above are the agreed routes, but these may change depending on local conditions.

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