On Saturday, 15 August 2026, flooding caused by a burst water main beneath Inner Ring Road West at Heathrow Airport blocked access to the airport’s central terminal area, including Terminals 2 and 3.
Access to Terminals 2 and 3 Blocked by Flooding
The flooding affected the central terminal area (CTA), which includes Terminals Two and Three and related buildings. Road closures remain in place restricting vehicle access to these terminals. There was no flooding inside Terminals Two or Three, and flights continue without disruption.
Passenger Advisories Urge Use of Rail and Park-and-Ride Services
Passengers are advised not to travel by road to Terminals 2 and 3 on 15 August 2026 due to flood-related closures. Heathrow Airport strongly recommends
using rail services including Heathrow Express, Elizabeth Line, and Piccadilly Line. Those who must drive should use Park and Ride facilities and access Terminals Four or Five, then transfer to Terminals 2 or 3 via the airport’s free rail service or change at local rail stations. Travelers are urged to allow extra time for their journeys.
Heathrow Airport Responds to Flood and Ongoing Road Closures
A Heathrow Airport spokesman said: “Flooding in the central terminal area has resulted in on-going road closures restricting access to Terminals 2 and 3.” He added: “Passengers travelling to or from either of these terminals today must not travel by road,” and “Passengers are
strongly advised to use Heathrow Express, Elizabeth Line and Piccadilly Line rail services where possible.” The spokesman also said: “Any passengers that must travel by car must use Park and Ride, head to Terminals 4 or 5 and take free rail services from there, or change at local rail stations.” He concluded: “Please allow extra time for your journey. Our teams are working to resolve the situation as quickly as possible, we apologise for any disruption caused.”
The disruption occurs amid the school summer holidays, a peak travel period with hundreds of thousands of customers at Heathrow Airport.
