M25 anti-clockwise shut between J13 and J11 overnight for roadworks

A planned carriageway closure on the M25 anti-clockwise between junction 13 (Staines) and junction 11 (Chertsey) was active overnight and scheduled to lift at 05:30 today, according to the estate's own traffic monitoring trigger. That closure sits within a wider pattern of roadworks activity on the motorway this week, according to [1]. Data pulled from National Highways and aggregated by M25traffic.co.uk, timestamped 06:07 on Wednesday 9 September 2026, shows sixteen planned roadworks scheduled across the M25 network, with none currently listed as active and no accidents reported at the time of the update, according to [1]. The source describes itself as drawing "main source of news and updates about roadworks... from Traffic England," which it calls "an official, reliable one," according to [1]. Among the other closures listed for the same period were a hard-shoulder closure on the anti-clockwise carriageway between junctions 30 and 29, a hard-shoulder closure clockwise between junctions 23 and 24, a full carriageway closure on the A282 northbound at the Dartford Crossing, a carriageway closure on the link road from J21 clockwise to the M1's J6A northbound, lane closures anti-clockwise between junctions 8 and 7, and lane closures clockwise within junction 28 — all listed with a start time of 05:45, according to [1]. It's worth flagging a wrinkle in the material: the source itself notes that by the 06:07 update, "0 Accidents" and "0 Roadworks active" were reported, even as it separately lists sixteen "planned scheduled" works including several marked "Road closed" or "Slip road closed" with timestamps showing they were "reported 22 min ago" — that is, logged only shortly before the update itself, according to [1]. The J13–J11 anti-clockwise closure named in today's trigger does not appear by name in the fetched list text, which instead itemises the J30–J29, J23–J24, Dartford Crossing, J21–M1 link, J8–J7 and J28 works specifically; National Highways' full data set for the day evidently includes more items than the ten of sixteen shown in this extract, according to [1]. Whether the J13–J11 closure was one of the six not itemised in this excerpt is unconfirmed by the material supplied. The source also carries a caveat about live traffic flow: it states it "now features real time traffic flow information from Google maps which will show how current accidents are slowing traffic speed," intended to be read alongside its roadworks listings, according to [1]. No congestion figures or delay estimates for the J13–J11 closure, or for any of the other listed works, are given in the material, according to [1]. For Wayne, the practical takeaway is narrow but clear: the anti-clockwise stretch between Staines and Chertsey was due to reopen at 05:30 this morning per the estate's own instrument, and it sits amid a busy overnight programme of at least sixteen planned works across the M25, per National Highways data relayed through [1]. Nothing in the material supplied indicates whether the reopening happened on schedule, and no source here reports current queue lengths on the anti-clockwise carriageway. What to watch: confirmation from National Highways or the same tracker that the J13–J11 anti-clockwise carriageway has reopened as scheduled, and whether any of today's other fifteen planned works overrun into the morning peak.
