HC Deb 05 November 1986 vol 103 c439W
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:

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.
