asked the Secretary of State for the Environment if he will provide a breakdown by trunk roads, principal roads and other roads of the expenditure figures for each of the years 1971–72 to 1975–76 on new construction and improvement and on maintenance, respectively, contained in the White Paper on Public Expenditure 1970–71 to 1975–76, Command Paper No. 4329.

The breakdown is expected to be broadly as follows:

	1971–72	1972–73	1973–74
	£m	£m	£m
New Construction and Improvements
Trunk Roads (including Motorways)	248·3	275·8	318·7
Principal Roads	188·6	210·3	227·6
Major Roads	436·9	486·1	546·7
Maintenance
Trunk Roads (including Motorways)	29·0	34·8	32·6
Principal Roads	50·2	54·4	56·0
Major Roads	79·2	89·2	88·6

These figures for "Other Roads" are shown separately in Table 2.9.Beyond 1973–74 the allocations have not been fully worked out. Local authority expenditure in particular is imprecise for the reasons given in paragraph 24 of Cmnd. 4829.
