The states snapped up this money greedily and the demand for more money became so great that in 1919 Congress appropriated $200,000,000 more, and still later, 1921, appropriated $75,000,000, and $15,000,000 for national forest roads. And still later, June 18, 1922, there was authorized an appropriation of $65,000,000 to be expended during the fiscal year ending June 30, 1923, and $75,000,000 for the succeeding fiscal year. At the end of five years after the passage of the Federal Aid road act, there had been completed under its terms 7469 miles of road and 17,977 miles additional were under construction. Texas ranked first in the number of miles completed, with 682; and Illinois had received the greatest amount of federal aid on projects completed and under construction, with $11,807,906; while Texas was a close second with $11,393,485. While the mileage built by Federal and state aid is less in the more compact densely populated Eastern states, the cost per mile is much more as much more expensive types of roads are being built. In the West and South earth roads largely make up the mileage. It has been objected that these do not properly come under the wish of Congress when it provided that the fund should be used only in the construction of “substantial” roads. Earth road advocates argue that such features as grading, draining and straightening roads may be considered permanent, in so far as the road is ready for any type of surfacing that may be desired to be laid at a later date. Recognizing the merits of both contentions The Bureau of Public Roads issued, in 1922, a decision practically as follows: The question of a more definite policy to be followed in connection with the approval of earth road Federal Aid projects which involve grading and drainage only, has for some time been under consideration, and it has been decided that hereafter such projects will only be approved on condition that The (State) Highway Department agree, in so far as it may legally do so, that within a reasonable time after completion of the improvement of the project as an earth road, it will place or cause to be placed thereon, an adequate and substantial type of surfacing. By adequate and substantial type of surfacing is meant such type as will carry the prospective traffic with such maintenance expenses that the total annual charges will represent a reasonable expenditure for the public service rendered by the highway. It seems, therefore, that the Government expects to assist in the financing of roads that appear adequate for the purposes intended.
