In late July 2026, a police‑led incident forced the closure of the M61 spur near Walton Summit and an accident on the M6 near Lancaster caused severe southbound congestion, with delays of up to 81 minutes and traffic moving at only a few miles per hour.

A few weeks later, in early August, separate incidents disrupted other major routes: a heavy‑goods‑vehicle breakdown blocked the Conwy tunnel on the A55 in North Wales, creating long tailbacks, while a collision on the A19 near Wolviston in Teesside partially blocked the northbound carriageway, reducing speeds to around 10 mph and causing further delays.

These events illustrate a pattern of sporadic but significant road incidents across the United Kingdom that have repeatedly led to major traffic disruptions on key motorways and arterial roads.
