M20 eastbound J10a entry slip shut overnight for roadworks

The eastbound entry slip road at M20 Junction 10a is currently closed for roadworks, with the closure active now and scheduled to end at 06:00 tomorrow, according to the estate's own traffic instrument that flagged this update. The closure sits within a much larger pattern of overnight works currently running across the M20 corridor. Londontraffic.org lists an active roadworks scheme on the M20 eastbound between Junctions 5 and 8, running from 20:04 on 23 June 2026 through to 06:00 on 8 July 2026, according to [2]. A parallel westbound scheme between Junctions 10 and 8 is also currently active, running from 20:10 on 22 June 2026 to 06:00 on 10 July 2026, according to [2]. Junction 10a itself appears repeatedly in the wider works schedule. The same source lists lane closures on the M20 eastbound between Junctions 9 and 10a, with lanes two and three affected, and on the westbound carriageway between Junctions 11 and 10a, with lanes two and three closed, both flagged as "roadworks are planned" with recurring overnight schedules, according to [2]. The exact times for those two entries were not fully captured in the material and should be treated as unconfirmed pending confirmation nearer the date. For drivers using the M20 to reach the Channel crossings, National Highways operates the separate Operation Brock contraflow system, which is designed to keep HGV traffic destined for the Port of Dover or Eurotunnel moving during Channel disruption while allowing other traffic to continue as normal, according to [1]. As of the material reviewed, the contraflow remains open for westbound and London-bound traffic, according to [1]. National Highways notes separately that it periodically needs to close the M20 to maintain the moveable concrete barrier used for Brock, distinct from the routine roadworks closures reported here, according to [1]. Wayne should note the broader picture: this is one closure among a dense schedule of overnight works stacking up along the M20 through late June and into July, spanning junctions from J1 through to J11, according to [2]. Many entries share the same pattern — closures running from 20:00 to 06:00, described as "planned" or "pending" — which points to a sustained period of disruption on this stretch rather than an isolated one-night job. What to watch next: whether National Highways confirms the J10a closure has lifted on schedule at 06:00, and whether the overlapping eastbound (J5–J8) and westbound (J8–J10) schemes, both still active into early July, produce knock-on congestion at the junction during the morning peak.
