Bob Spink: To ask the Secretary of State for Transport at what point he estimates the proposed Benfleet Tunnel Crossing, connectingEssex with the possible Cliffe airport, will go underground (a) on the mainland near Sadlers Farm, (b) on North Canvey nearWaterside Farm and (c) on South Canvey near Thorney Bay. [73571]Mr. Jamieson: The South East and East of England Regional Air Services study (SERAS) analysis has not attempted to identify thelocation and design of highway connections for either the Cliffe option or any of the published options.As is made clear in The Future Development of Air Transport in the United Kingdom (South East)consultation document (paragraph 11.13), a second road crossing of the Thames to the A13/A130 at Benfleet could, in time, be neededto give better access to the labour market north of the Thames.
