HC Deb 02 May 1977 vol 931 c33W
Mr. Hayhoe

asked the Secretary of State for Transport what increases in traffic flows at the Hogarth roundabout, Chiswick are estimated to arise from the increase in passenger and freight traffic expected at Heathrow in the next three, five, seven and 10 years.

Mr. Horam

Predictions of Heathrow traffic flows at the Hogarth roundabout, Chiswick are not available. Future levels of airport traffic at this junction will be influenced by, for instance, the extension of the London Underground system to Heathrow.
