Overview
- The M1 in South Yorkshire remains closed in both directions between J36 (Tankersley) and J37 (Barnsley) for police collision investigation after a car left the carriageway, with no confirmed reopening time and long tailbacks reported.
- The M20 in Kent is closed in both directions between J8 (Hollingbourne) and J9 (Ashford) after a crash involving a van and a car shortly after midnight, with signed diversions sending traffic onto the A20.
- Flooding on the M6 in Cumbria forced a full northbound closure between J41 (Catterlen) and J42 (Carlisle) and a lane three closure southbound; National Highways set a B5303/A6 diversion, and a later update reported reopening with residual delays.
- On Wednesday evening, a collision on the M6 Thelwall Viaduct between J20 and J21 temporarily halted northbound traffic before all lanes reopened, leaving lengthy queues to clear.
- National Highways, police and traffic services issued live advisories, diversion details and ETAs as heavy rain and weather warnings complicated clear‑up efforts and added to wider congestion on routes around Greater Manchester and near Bristol.
