From Names to Numbers: The Origins of the U.S. Numbered Highway System
/ref> In the approved U.S. Numbered Highway System numbering plan in 1926, US 30 split between Idaho and Wyoming. US 30N, the northern route, passed directly from Wyoming to Idaho, while a southern route entered Utah. Eventually the northern route became mainline US 30, leaving US 30S as an alternate route. In the state of Utah's route logs, US Route 30S is acknowledged as late as 1970 in numerous highway transfer resolutions as segments of interstates 80 and 80N were completed. However, all references to US 30S are gone from the state's highway resolutions by the time the state requested a designation change of I-80N to its modern designation of I-84 in 1977. In all three states, the freeway replacements used shorter, straighter alignments compared to the former US 30S; some small towns were bypassed when the two-lane roads were replaced with freeways. A significant case is at the Idaho state line, where I-84 runs roughly to the east of the former US 30S. Portions of the former alignment of US 30S in this area are now designated Idaho State Highway 81, Utah State Route 42 and Utah State Route 30. Another significant deviation is at the eastern terminus of US 30S, where Interstate 80 was routed several miles south of Granger, bypassing the town.
