The Transport Secretary Philip Hammond confirmed the coalition's opposition to a third runway at Heathrow Airport whilst giving evidence to the Transport Committee on 26 July.
He said he wanted to use experts from the air traffic control and airport industry to see how the airport can be made more effective and efficient.
During the evidence session on the government's policies on transport he admitted that transport would be affected by government budget cust.
He told the committee that government's objective is to deliver the whole of Crossrail as already proposed, however he said the project has to be "affordable".
On questioning by the committee chair Louise Ellman he said that the future of the free bus pass for over 60s would remain, but didn't rule out changes on age eligibility.
Road projects already shelved by the coalition government include the £1.1bn widening of the A14 between Cambridge and Huntingdon and a £23m scheme to improve road junctions and buses on the A2 in Kent, both of which were due to start this year.
Responding to Conservative MP Angie Bray he ruled out road charging for existing roads, but said he was "open to suggestion" on funding new roads through private capital supported by tolling or charging.
The Transport Secretary said he had halted work on building 1,400 new train carriages, pending the outcome of October's public spending review.
