US 189 north end, 1990s-present
Heber City (there is an "End US 189" sign here, but AASHTO has never been asked to decommission US 189 between here and the Wyoming border, and in fact UDoT's own records indicate that US 189 ends at the same place US 40 ends, near Park City.)
US Highway endpoints in Utah
The URL for this map ends with the 2-letter state abbreviation "UT"; if you'd like to see endpoints in Colorado, just replace the "UT" with "CO". You can quickly jump to any other state using that method, with a few exceptions: for any of the six New England states, use "ME". For Delaware, use "MD". For Nevada, use "CA".
