The alternate use of Heathrow’s runways during the day will not be possible for six weeks after September 13th because of essential maintenance work.
The work will be taking place on taxiways that link the airport’s northern runway to the rest of the airfield in order to prevent debris getting into aircraft engines.
Some of the taxiways have been laid on top of concrete blocks, which can become unstable over time. This can cause the asphalt to break up and disintegrate, which represents a potential hazard to moving aircraft.
While alternate daytime use of Heathrow’s runways won’t be possible, alternation during the night will remain unaffected.
Colin Wood, Heathrow’s director of airside operations, said he realises the news will not be welcomed and apologised to passengers ahead of any inconvenience.
"We would not suspend alternation if there was any other alternative. This work is critical to the future safe operation of Heathrow," he explained.
Earlier this week, Heathrow lent its backing to England’s bid to host the 2018 World Cup. The airport is seen as a key part of the bid thanks to the 180 destinations and 90 airlines it serves and accommodates.
