UK: Technical Issue Shuts Road Tunnel to Heathrow Terminal, Triggers Major Congestion

A technical issue forced the closure of a road tunnel to Heathrow Airport’s Terminals 2 and 3 on Tuesday, August 5, causing major congestion and long lines. Some passengers abandoned their vehicles and walked with luggage. The tunnel later reopened, but delays persisted, and travelers were urged to allow extra time and use public transportation.
