This business loop shield is unusual for its large numerals, but this kind of shield is becoming more common in Wyoming. Business U.S. 30 is conspicuously unsigned here. City Market is a regional supermarket chain found in southwestern Wyoming, and it is especially prevalent in Rock Springs and Green River. Photo taken by Mike Ballard, 8/98. Here, Business Loop I-80 in Rock Springs is signed with a neutered shield. This is quite uncommon in Wyoming, as nearly all standalone Wyoming Interstate shields contain the state name. Photo taken by Mike Ballard, 8/98. Signage for Westbound Business Loop I-80, Westbound U.S. 30, and Southbound U.S. 191 in Rock Springs just north of the Interstate 80/Dewar Drive exit (Exit 102) looking in a southeasterly direction. Although not shown as such, Dewar Drive is actually Business Loop I-80. This is because it is assumed most traffic seeing this sign are headed for the Interstate and not for the business route. Photo taken 9/97. Westbound Business Loop I-80 and Business U.S. 30 follows Dewar Drive at the northwest end of Rock Springs. This view is afforded from westbound Interstate 80 and U.S. 30-191 looking north. Photo taken 09/06/05. Page Updated September 25, 2005.
