§ Mr. Peter Bruinvels asked the Secretary of State for Transport what is the cost to date for the construction of the M25-M1 interchange, the budgeted cost for completion, and the likely cost for this completion.
§ Mrs. ChalkerThe costs for the M25-M1 interchange cannot readily be separated from the total costs for contract 2 of the Micklefield Green to South Mimms section of M25, which also includes lengths of the main M25 carriageway on both sides of the interchange and a junction with A405 to the east. The estimated main works cost for contract 2 was given as £24.7 million at November 1982 prices in "Policy for Roads in England: 1983". The final main works cost will depend on the rate of inflation throughout the contract and the determination of any contractual claims. The estimate at current prices is approximately £21 million, of which £15.7 million has already been spent.
