M25 (JUNCTIONS 14 TO 26) AND M4 (JUNCTIONS 1 TO 15) MOTORWAYS
TEMPORARY TRAFFIC RESTRICTIONS
Notice is hereby given that National Highways has made an Order on the M25 Motorways in the Counties of Hertfordshire and Essex, the Unitary Authorities of Slough Windsor & Maidenhead, Buckinghamshire Council, Reading, Bracknell Forest, West Berkshire, Swindon, and Wiltshire and the London Boroughs of Hounslow, Hillingdon and Enfield, 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 the road. The effect of the Order is, in phases, to:-
1. authorise the overnight closure of -
(a) sections of both carriageways of the M25 between Junction 14 (A3113/Heathrow Spur Road) and Junction 26 (A121);
(b) both carriageways of the M4 between Junction 1 (A4/A205/A315/ A406) and Junction 5 (A4);
(c) both carriageways of the M4 between Junction 5 (A4) and Junction 15 (A419/A346);
(d) all slip and link roads leading to and from the lengths of carriageway described in 1. (a) to (c) above;
(e) the circulatory system at M25 Junction 21A (A405), M25 Junction 23 (A1(M)/A1), M25 Junction 25 (A10), M4 Junction 3 (A312) and M4 Junction 4 (Heathrow Spur Road/A408), M4 Junction 8/9 (A308(M)/A404(M)), Junction 13 (A34) and M4 Junction 15 (A346/A419);
(f) the hard shoulder adjacent to the lengths of carriageway and slip roads in 1. (a) to (c) above; and
(g) any emergency refuge area adjacent to the lengths of carriageway in 1. (a) to (c) above.
2. authorise the overnight use of the hard shoulder adjacent to the lengths of carriageway and slip and link roads described in 1. above.
3. permit HGVs in the outside lane of the lengths of carriageway described in 1. (a) to (c) above, during inside-lane closures.
These measures are in the interests of road safety while contractors undertake maintenance and renewal work of a cyclical nature and M25 and M4 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 3rd January 2023.
Overnight closures on the M4 and connecting roads between Junctions 5 and 15 will be in operation between 21:00 and 06:00 (maximum period). Overnight closures on the M4 between Junctions 1 and 5, and the M25, will be in operation between (maximum period): Monday - Thursdays 22:00 - 05:30, Fridays 23:00 - 06:00, Saturdays 22:00 - 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. In such cases less disruptive options will be considered. The Order will come into force on 2nd January 2023 and shall remain in force until 24th December 2023.
Traffic affected by the closures will be diverted via other junctions of the M25 and the M4, or by using the M40, A1, A1(M), A4, A10, A33, A34, A41, A308, A308(M), A312, A322, A327, A329(M), A338, A339, A355,
A404(M), A404, A405, A406, A412, A414, A419, A1081, A3044, A3113, A3290, A4155, and the B4192. The diversion in operation will vary according to the closure in force, and the diversion roads 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 will be clearly indicated by traffic signs when they are in operation during the works period.
