Historical Route Historical Route

US Highway Shield ACR 123 (Resolution Chapter 104, 8/16/2006) designated segments of former U.S. Highway Route 80 in San Diego and Imperial Counties as Historic U.S. Highway Route 80, and requested the Department of Transportation to design and facilitate the posting of appropriate signs and take related actions in that regard. The resolution noted that US 80, largely parallel to current I-8, was a 180-mile highway spanning San Diego and Imperial Counties from San Diego Bay to the Colorado River, and played a major role in the development of this state during much of the 20th century. In 1909, California voters approved a statewide bond measure for road improvement purposes in the amount of $18 million, providing, among other things, funds to construct a road between San Diego and Imperial Counties, and their county seats of San Diego and El Centro. In 1915, a unique wood plank road was built over the Imperial Valley sand hills, resulting in a shorter route. In 1925, the federal government became involved in standardized highway route designations across the nation and even numbers were assigned to major highways running east and west, and odd numbers for highway running north and south. The numbering of highways proceeded in numerical order beginning in the north and east and continuing south and west, respectively, and, as a result, the routing along California's southern border was formally designated as US 80. This road, from San Diego to Tybee Island, Georgia, was adopted as US 80 on November 11, 1926. US 80 was the first ocean-to-ocean transcontinental highway to be completed, and portions of the route were known as the Bankhead, Broadway of America, Dixie, Lee, Old Spanish Trail, and Southern Transcontinental Highway.
