After graduating with a civil engineering degree from Cornell University, Herbert S. Fairbank joins OPR as a student engineer assigned to a good roads train. Throughout his long career with the Agency, he would have a profound influence on the country. Among his many achievements, he was the chief author of Toll Roads and Free Roads (1939) and Interregional Highways (1944), the two documents that established the basis for the Dwight D. Eisenhower System of Interstate and Defense Highways. These reports were based to a large extent on the 1930's highway planning surveys, which he oversaw from start to finish.

Near Ottawa, IL, full-scale testing begins for the AASHO Road Test, designed by BPR, AASHO, and the HRB to obtain data on all significant variables affecting pavements and short-span bridges. Portland cement concrete and asphaltic pavement sections, as well as 16 short-span bridges, are included in the 7-mile long specially constructed test facility. Under direction of the HRB, the tests are being financed by the highway bureaus of the 48 States, Hawaii, the District of Columbia, and Puerto Rico, with financial support from BPR, the Automobile Manufacturers Association, the petroleum industry, and the American Institute of State Construction. The Department of Defense furnished heavy vehicles for the test runs. By completion of the tests in November 1960, a total of 1,114,000 axle loads will have been applied to the pavements and bridges, providing the information needed to develop a more refined and scientific design of pavements and short-span bridges.
