National Highways

M1 (Junctions 1 To 8) And M25 (Junctions 14 To 26) Motorways & A1 Trunk Road Temporary Traffic Restrictions

Notice is hereby given that National Highways has made an Order on the M1 and M25 Motorways, and A1 Trunk Road, in the Counties of Hertfordshire and Essex, the Unitary Authorities of Slough and Buckinghamshire Council, and the London Boroughs of Hillingdon, Harrow, Enfield and Barnet, 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) both carriageways of the M1 between Junction 1 (A406) and Junction 8 (A414);

(b) both carriageways of the M25 between Junction 14 (A3113/Heathrow Spur Road) and Junction 26 (A121);

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

(d) the entire circulatory system at M25 Junction 21A (A405), M25 Junction 23 (A1(M)/A1) and M25 Junction 25 (A10);

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

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

2. authorise the overnight closure of -

(a) both carriageways of the A1 between Bignalls Corner (A1(M) Junction 1/M25 Junction 23) and Borehamwood Interchange (A5135), and any slip and link road leading to and from this length of carriageway;

(b) authorise the overnight closure of any lay-by, bus stop or gap in the central reservation adjacent to the lengths of carriageway described in 1. (c) above; and

(c) authorise the overnight closure of any side road at junction with the lengths of carriageway described in 1. (c) above.

3. authorise the overnight suspension of the Motorway Regulations prohibiting use of the outside lane by HGVs on the lengths of carriageway described in 1. (a) and (b) above.

4. authorise the overnight use of the hard shoulder adjacent to the lengths of carriageway described in 1. (a) to (b), and any slip/link road described in 1. (c), above.

These measures are in the interests of road safety while contractors undertake maintenance and renewal work of a cyclical nature and M1, M25 and A1 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. The overnight closures 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 remain in force until 24th December 2023.
Traffic affected by the closures will be diverted via other junctions of the M1, M25 and A1, or by using the M4, M11, M40, A1(M), A4, A10, A41, A404, A405, A406, A411, A412, A414, A1081, A3044, A3113 and
the A5183. The diversion in force will vary according to the closure in force, and the roads listed 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.
