The effect of the Order is to: -

2. authorise overnight hard shoulder running adjacent to the lengths of carriageway and slip and link roads described in 1. (a) to (e) above.

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

4. authorise the overnight closure, in sections, of –

5. to impose, in sections as required, an overnight ban on overtaking on the A21 where it is currently permitted on the lengths of carriageway described in 4. (a) above.

These measures are in the interests of road safety while contractors undertake maintenance and renewal work of a cyclical nature and M25, M20, M26, A20 and A21 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.

The overnight closures on the M25, M20 between Junction 1 and Trottiscliffe Road Overbridge, M26, and the A20, 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

The overnight closures on the M20 between Trottiscliffe Road Overbridge and Junction 13 and the A21 will be in operation between 20:00 and 06:00 (maximum period).

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, M20, M26 and the A21, or by using the M3, A2, A3, A20, A22, A23, A24, A25, A26, A28, A30, A31, A217, A223, A224, A225, A227, A228, A229, A240, A245, A249, A262, A264, A282, A308, A317, A320, A331, A2014, A2018, A2025, A2100, A3044, A3113, B245, B2087, B2162, B2173, and local roads as necessary. 

The diversion in operation will vary according to the closure in force, and the diversion roads listed are the agreed routes, but these may change depending on local conditions. 

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

Access to and from premises accessible from, and only from, the lengths of carriageway in article  4. above to be closed will be permitted under works control.
