A12 Mr. Irvine To ask the Secretary of State for Transport what were the traffic flows along the A12 between (a) the M25 interchange and Chelmsford, (b) Chelmsford and Witham, (c) Witham and Colchester and (d) Colchester and Ipswich for each year from 1985 to 1989; and if he will indicate the division between heavy goods vehicles and other traffic. Mr. Chope Information is not available in exactly the format requested. However, representative data are available for daily traffic flows between the following points on the A12 trunk road: Mr. Freeman The figures for investment in the Underground since 1974 are as follows:------ |Year| ------ |1974| ------ |1975| ------ |1976| ------ |1977| ------ --------- |1978 | --------- |1979 | --------- |1980 | --------- |1981 | --------- |1982 | --------- |1983 | --------- |1984–85| --------- |1985–86| --------- |1986–87| --------- |1987–88| --------- |1988–89| --------- |1989–90| --------- | | --------- The London Regional Transport Act came into force in 1984. However, the level of the Underground's funding for 1984–85 was determined by the GLC. On current estimates, Underground investment in 1990–91 will be two and a half times higher, in real terms, than in 1984–85. Mr. John Marshall To ask the Secretary of State for Transport what surveys have been made of the impact of the opening of the channel tunnel in 1993 and of the Waterloo link upon the numbers travelling by the Northern line. Mr. Freeman A survey carried out by Halcrow Fox for British Rail in 1989 estimated the numbers of channel tunnel passengers that would be using the Underground. London Underground is making use of the resulting data in its strategic planning.
