Wyoming Highway 28 (WYO 28), also known as the South Pass Highway, is a 96.46-mile (155.24 km) state highway in Sweetwater, Sublette, and Fremont counties in Wyoming, United States, that connects Wyoming Highway 372 (WYO 372), southeast of Fontenelle, with U.S. Route 287 / Wyoming Highway 789 (US 287 / WYO 789), south-southeast of Lander.
Route description
Sweetwater County
WYO 28 begins at a T intersection with WYO 372 (La Barge Road) in Sweetwater County, just north of a western arm of the Seedskadee National Wildlife Refuge (Seedskadee NWR) and roughly 14 miles (23 km) southeast of the census-designated place (CDP) of Fontenelle. (WYO 372 heads north toward Kemmerer and La Barge and south through the arm of the Seedskade NWR and then on toward Green River and Rock Springs.)
From its western terminus WYO 28 proceeds northeasterly as a two lane road for its entire length. After approximately 2.8 miles (4.5 km), WYO 28 enters the Seedskadee NWR, crosses the Green River, and then leaves the Seedskadee NWR. At about 28.82 miles (46.38 km) along its route, and just after crossing the Big Sandy River, WY0 28 has its junction with U.S. Route 191 (US 191) on the southern border of the CDP of Farson in Eden Valley. (US 191 heads north toward Pinedale and Jackson and south toward Eden and Rock Springs.)
East of its junction with US 191, WYO 28 very briefly passes through the southern edge of Farson before continuing roughly 2.4 miles (3.9 km) along the southern border of the CDP, with the meanders of Little Sandy Creek to the south. As WYO 28 crosses the Little Sandy Creek, it leaves Farson
CR 108 and continues for about 14.5 miles (23.3 km) before leaving Sweetwater County.
Sublette County
Upon leaving Sweetwater County, WWO 28 enters Sublette County. With the exception of a single paved turnoff, there are only a few unnamed dirt side roads along the 3.75 miles (6.04 km) section of WYO 28 that are within Sublette County. The nearly 1,900-foot (580 m) turnoff includes a historical marker and gravestone. Upon leaving Sublette County, WYO 28 enters Fremont County.
This brief starts where responsible research should: with the source description of “Wyoming Highway 28” as state highway in Sweetwater, Sublette, and Fremont counties in Wyoming, United States. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as state highway in Sweetwater, Sublette, and Fremont counties in Wyoming, United States. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 28, 2026. The linked authority identifier is Q2508779. Authority coordinates are 41.868, -109.858. None of the 2 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
