My guess is that this would be for the third runway that will be built to the north of the current airport, this will be as a result of the canceling of the HS2 project that has been found to be economically unviable following the disclosure of secret government documents that were released following court proceedings last week.
For those outside the UK HS2 is a proposed high speed rail link between London and Birmingham.
