Overview
- The M4 is closed in both directions between J10 (Wokingham/A329M) and J11 (Reading) for SSEN emergency works after structural damage was found on a nearby high‑voltage pylon, with National Highways warning the shutdown would last through the morning peak on February 18.
- National Highways cited forecast strong winds as a factor for urgent repairs and set signed diversion routes using hollow square and hollow circle symbols on local roads around Reading and Wokingham.
- The Metropolitan Police said a pursuit that began around 03:15 on February 17 ended on the M4 westbound before J10; a man in his 30s was arrested, taken to hospital with non‑life‑threatening injuries, and the crash caused fuel spillage and barrier damage that required resurfacing.
- The M25 clockwise within J25 (Waltham Cross) was closed overnight for emergency resurfacing after a lorry fuel leak, with traffic diverted via exit and entry slip roads as contractors worked on the damaged surface.
- Separate incidents continued to strain the network, including the M60 clockwise closure between J25 and J26 after a two‑car crash that sent two to hospital (one seriously), an earlier M1 southbound shutdown between J15 and J14 for a multi‑vehicle crash and fire, a fresh M1 northbound restriction near J12–J13 for recovery, an M11 lane closure causing lengthy delays, and an M48 collision later cleared.
