M25 J11 clockwise exit slip shut for roadworks, queues building this weekend

The M25 junction 11 clockwise exit slip road was closed from 09:23 on Saturday 10 October 2026 for roadworks, and is scheduled to remain shut until 05:00 on Monday 12 October, according to [1]. The closure is listed as "PLANNED" on the estate's own monitoring feed, matching the construction works reported live on the M25 roadworks tracker. By 09:37, just 14 minutes after the closure was first reported, National Highways' live data — relayed via [1] — showed overhead signs already warning drivers of queues in both directions. Clockwise signs between junctions 9 and 10 were set to "QUEUE AFTER JCT" at 09:32, with further "QUEUE AHEAD" and "QUEUE CAUTION" messages posted on four clockwise signs at the same time, according to [1]. Anticlockwise traffic was also affected, with congestion signs set on the J16 exit slip and queue warnings posted between junctions 15 and 16, per [1]. A red X lane closure was separately recorded between junctions 12 and 13 on the clockwise carriageway from 09:02, according to [1] — a different location from the J11 exit slip works, and the source does not suggest the two are connected. No accidents were reported on the M25 at the time of the 09:37 update, according to [1], so the congestion appears to stem from the roadworks themselves rather than any incident. The source gives no detail on the nature of the construction at J11 or an expected reopening before the stated Monday deadline, and nothing in the material explains why the slip required closure. For comparison, a separate National Highways page on ongoing works near junction 10 — covering the A3 Wisley Interchange upgrade — details a long programme of overnight lane and slip closures through the summer, according to [2], but that page does not reference the J11 clockwise exit slip at all and appears to be a distinct, longer-running scheme several miles away. For Wayne, the practical takeaway is straightforward: anyone routed via the M25 clockwise through junction 11 this weekend should expect the exit slip to be unusable until Monday morning, with knock-on queuing already visible as far back as junction 9. The anticlockwise congestion near junctions 15–16 looks, on current evidence, like separate peak-period traffic rather than a related problem, but the source material doesn't rule out some connection. What to watch next: whether the J11 slip reopens on schedule by 05:00 Monday, and whether National Highways publishes further detail on the nature of the works or any diversion route for traffic normally using that exit.
