§ Mr. Peter Bruinvels
asked the Secretary of State for Transport what is the cost of maintenance per mile of the M3 and how this figure compares with the average for other motorways; if he will give a separate figure for the M1 and M25; if he will indicate which is the most expensive section of the M3 to maintain; and how often the stretch between junctions 3 and 4 has been repaired in each of the last five years.
§ Mr. Peter Bottomley
Motorway maintenance costs vary considerably with the age of the road and the incidence of major renewal schemes. Expenditure on structural maintenance in 1984–85 was as follows:
£/mile M3 82,592 All motorways 66,059 M1 149,657 M25 4,511
The highest expenditure so far on structural maintenance of the M3 has been incurred between junctions 3 and 4, the first section to be opened in 1971; 5.6 miles of both carriageways of this section have been renewed under a phased programme of five schemes undertaken between 1981 and 1986, at a total cost of about £6.5 million.
