A-4: Mileage of new toll roads is shown in schedule 7.

NOTE. No rural-urban segregation available. It is possible that some of these roads may pass through public lands, but the mileage involved has not been determined.

4-5: It is assumed the "Total" mileage requested here relates to mileages estimated to be in service at the end of the 10-year construction program. Schedule 8 shows this information for each State, broken down into rural and urban. No estimate is available as to the probable amounts of total miles in service that will be in the toll-road and free-road categories.

A-6: The percentage distribution, by States, of mileage estimated to be in
service at the end of the 10-year program is shown in schedule 9.

SCHEDULE 9.-Percentage distribution, by States, of mileage estimated to be in
service on Jan. 1, 1965-Interstate System

A-7 to A-10: Information is not available according to this classification.
A-11, A-12: Data pertaining to the mileage of toll roads in each State as a
percentage of the total is shown in schedules 6 and 7.

B-1, B-2: Costs of reimbursements for free roads, 1947-51, and 1952-55 have
not yet been determined. This requires a section-by-section estimate of deprecia-
tion of those portions subject to reimbursement. A record of the original cost
of sections constructed with Federal aid is, however, available. These original
costs are listed in schedules 10 A, B, C, and 11 A, B, and C. Mileages shown are
obtained from Federal-aid accounting records and represent contract lengths and
should not be interpreted as reflecting net construction mileage. From the total
costs shown, depreciation is to be deducted. From the depreciated cost a further
deduction of 10 percent is to be made, and also the total amount of the Federal-
aid funds used. The final result will be the reimbursement amount, or credit to
which the State is entitled.

Schedules 10 and 11 show only those costs of free portions of the Interstate
System improved as Federal-aid projects. They do not include work that may
have been done wholly with State funds (no Federal-aid participation). The
amount of such work has not been estimated, but it is known to be small in total
amount.

B-3: The estimated reimbursements for toll roads, as computed from maxi-
mum allowances in S. 1160, are shown in schedule 12.

B-4: There are no costs, aside from those already mentioned, that are in the
reimbursable category.

B-5: These subtotals are not now available. Estimates of depreciation have
not yet been made; and estimates of work done by States with no Federal-aid
participation are not currently available.

B-6, B-7: For B-6 and B-7 the net mileage of free roads constructed with
Federal-aid has not been specifically determined; nor has the exact mileage of
eligible roads built without Federal-aid participation been inventoried.

B-8: Comparison of average costs per mile of reimbursements for toll roads as
compared with the national average is shown in schedule 13.
