| 1923 | Secretary of Agriculture Henry C. Wallace holds a hearing in Washington DC, to decide which of two competing alignments west of Salt Lake City, UT--the Lincoln or the Victory Highway--will be included in the Federal-aid system. On June 6, Wallace chooses the Victory Highway via Wendover, UT, proposed by the State. That alignment became U.S. 40 (1926), then I-80 (1957), while the Lincoln Highway route became U.S. 50 (the June 1986 issue of Life referred to Nevada's U.S. 50 as "The Loneliest Road" in America). |
