Heathrow Airport has instructed passengers not to drive to Terminals 2 and 3 due to significant flooding caused by a burst water main. The airport strongly advises travelers to utilize public transportation, including the Heathrow Express, Elizabeth line, and Piccadilly line, as roads around the affected terminals remain closed.
Passengers needing to travel by car were directed to park at Terminals 4 or 5 and then transfer via free rail services, or to park at local rail stations. The flooding, originating from a burst main beneath Inner Ring Road West, caused disruption in the central terminal area. Despite the road closures, there is no flooding within the terminals themselves, and flight operations have not been affected.
In an update, Heathrow announced that all roads have since reopened and that the airport is operating normally. The airport apologized for the inconvenience and thanked passengers for adhering to the advisories while teams worked to resolve the situation.
Airlines operating from the affected terminals, including Virgin Atlantic and British Airways, confirmed that their flights are running on schedule. Virgin Atlantic advised customers to use public transport or park and ride facilities.
This incident follows a recent grass fire that temporarily closed one of Heathrow's runways and a previous flooding event in May caused by a burst water main, which disrupted all rail services to and from the airport.
