Flooding caused by a burst water main beneath the Inner Ring Road West within Heathrow Airport’s Central Terminal Area restricted road access to Terminals 2 and 3 on 15 August 2026. The leak occurred beneath a key road connecting the terminals and adjacent buildings, leading to ongoing road closures around these terminals.
Travel Alternatives and Passenger Guidance
Heathrow Airport advised passengers not to travel by road to or from Terminals 2 and 3 today. Instead, travelers were urged to use rail transport options including the Heathrow Express, Elizabeth Line, and Piccadilly Line services. Those traveling by car were directed to park at Terminals 4 or
5, then transfer to Terminals 2 and 3 via free rail shuttles or through local rail stations, with additional journey time allowed.
Terminal Operations and Response Efforts
The flooding did not impact the interior of Terminals 2 or 3, and flight operations remained unaffected on 15 August 2026. Heathrow Airport teams were actively addressing the situation to restore full road access. A spokesman confirmed that road closures remain in place as the repairs continue and apologized for the inconvenience during the busy school summer holiday period.
