The early days of the Interstate Highway System were marked by significant changes and political maneuvering .  The short history of Interstate 82S (and 82N) is an overlooked example.  Born in 1957 during the original Interstate numbering plans, Interstates 82N and S, as well as their parent Interstate 82, were to run from Interstate 15 in Idaho (I-82N) and Utah (I-82S), respectively, to Interstate 5 in Portland, Oregon. The original (August 1957) approved Interstate system numbering.  These 'paper' designations would last less than a year as new corridors and some politicking would make changes, specifically to the Western I-82 and its two branches I-82N and I-82S.  There was an eastern I-82 proposed via a Scranton to New York City Corridor.

The 8,431-foot-high Teton Pass lies in the Teton Range of the Rocky Mountains within Teton County, Wyoming.  Presently Teton Pass is crossed by Wyoming Highway 22 and Idaho State Highway 33.  At one point the highway over Teton Pass was signed as US Route 20 Alternate.  US Route 20 Alternate was over Teton Pass never formally approved by the American Association of State Highway Officials nor has the corridor ever been officially part of a US Route.  The image above was taken from the 1949 Rand McNally Map of Idaho, Wyoming and Montana which shows US Route 20 Alternate branching from US Route 20/US Route 191 near Sugar City, Idaho and crossing Teton Pass towards Jackson, Wyoming.   Part 1; the history of US Route 20 Alternate over Teton Pass No major Auto Trail was ever assigned to Teton Pass as evidenced by the 1925 Rand McNally Map of Idaho, Montana and Wyoming .  On the Wyoming side Teton Pass can be seen as part of Wyoming Highway 25 ("WY 25") wher...
