“ Making an estimate of this magnitude is a complex engineering job and requires exercise of sound judgment in forecasting probable highway needs of each State in the calendar year 1975. The basic elements of the job have been done in the individual State highway departments where there is available the largest collection of needed basic data, skills, and experience bearing on the highway problems of each State. ”

“ Because of the large amount of information in some of the tables in the appendix, they are subdivided into three parts: Part a refers to toll roads; part b to free roads; and part c to toll roads plus free roads, combined. ”

“ Approved routes, including additions, are shown on the maps herein, one for each urban area. All urban areas on the National System of Interstate Highways not shown in this folio are served by the Interstate routes previously approved passing through or around these urban areas. ”

“ Pending the necessary engineering studies to determine the most economic alinements, the location of these routes was diagrammatic only, and for convenience and in the absence of detailed engineering studies, their lengths were measured along the existing principal highways. ”

“ Thus it is indicated from the estimates made in 1956-57 that the combined Federal-aid and required State matching finances needed after July 1, 1956, to ny ape the Interstate System would be about 37 percent greater than the amounts which have been authorized in the 1954 and 1956 acts. ”
