Overview
- Planned overnight resurfacing on the M25 anti‑clockwise between Junction 27 (M11) and Junction 25 (Enfield) overran and led to a full closure that produced multi‑mile queues during Friday morning rush hour.
- National Highways said engineers identified infrastructure defects that needed immediate repair and that the main carriageway was reopened where safe while lane and link‑road closures remain in place.
- Separately, emergency repairs on the M20 westbound in Kent closed the motorway between Junction 3 and Junction 1 with no estimated reopening time as crews work on a safety‑critical fault.
- Reported congestion and delay figures vary across sources, with outlets and traffic maps showing between about six and ten miles of queues and journey‑time impacts ranging from roughly 45 to 90 minutes due to timing and measurement differences.
- National Highways is mobilising specialist crews, stressing final safety checks are required before full reopening and urging drivers to allow extra time, re‑route or avoid the areas because local roads may face knock‑on congestion.
