Flooding caused by a burst water main beneath the Inner Ring Road West at Heathrow Airport has led to ongoing road closures restricting access to Terminals 2 and 3 on the morning of Saturday, 15 August 2026. The affected area is within the airport’s Central Terminal Area, which includes Terminals 2 and 3.
Road closures prevent vehicle access to Terminals 2 and 3 due to floodwater resulting from the burst main leak. Heathrow Airport confirmed no flooding has occurred inside these terminals, and flights remain unaffected by the water main incident. However, travel to and from these terminals by road
is currently blocked.
Transport Alternatives and Passenger Guidance
Heathrow Airport has advised passengers not to use road transport to reach Terminals 2 and 3 during the ongoing flooding situation. Instead, travelers are urged to use rail services including the Heathrow Express, Elizabeth Line, and Piccadilly Line to access these terminals. For those traveling by car, the airport recommends using Park and Ride facilities at Terminals 4 or 5, followed by free rail connections to Terminals 2 and 3, or changing at nearby rail stations.
Passengers are also advised to allow additional time for their journeys to accommodate the disruption and transport modifications.
Official Statements and Response
A Heathrow Airport
spokesperson detailed that flooding in the Central Terminal Area has necessitated road closures limiting access to Terminals 2 and 3. The spokesperson emphasized that passengers must avoid road travel to these terminals on 15 August 2026, urging the use of rail options where feasible. Those requiring car access are instructed to use the Park and Ride at Terminals 4 or 5 combined with free rail links or transfers at local rail stations.
The airport’s teams are actively working to resolve the flooding and related disruptions as quickly as possible, while apologizing for any inconvenience caused to passengers.
Context Amid Peak Summer Travel
The flooding and
resultant travel disruption occur during the school summer holiday period, when Heathrow experiences peak passenger volumes, with hundreds of thousands of travelers passing through the airport. The road closures at Terminals 2 and 3 add travel complications amid these high traffic levels on 15 August 2026.
