§ Mr. Shersby
To ask the Secretary of State for Transport, pursuant to his answer of 26 June to the hon. Member for Uxbridge, what were the reasons for the increase in the estimated cost of the A40 Western avenue improvement at the junction with Long lane, Hillingdon from £18.2 million between November 1987 at 1986 prices to £34.1 million at 1987 prices.
§ Mr. Atkins
The most significant element in the increase in the estimated cost of constructing the scheme was that the cost of piling and structural work in London has402W exceeded the rate of inflation. In addition, there were increases in the cost of London Underground's scheme to reconstruct Hillingdon station to higher, more up to date standards.
