trumpet interchange that connects with the eastern terminus of
WYO 374. The highway heads southeast parallel to the
Green River along Flaming Gorge Way through the center of Green River. Near the east end of the city, I-80 BL parallels a

Rawlins Subdivision and the eastern end of the
Evanston Subdivision. Next to the railyard, the business route has an intersection with
WYO 530 (Uinta Drive), which heads north, then curves back south and bridges the business route and the railyard on its way to the portion of the city south of the Green River. Immediately east of WYO 530, I-80 BL rejoins the mainline Interstate at exit 91, another trumpet interchange. ;Major intersections

Laramie Subdivision rail line at the western city limits of Cheyenne.
WYO 225 (Otto Road) heads southwest from the interchange and I-80 BL and
US 30 head east along Lincolnway. The interchange has no ramp to eastbound I-80; that movement is made via the business route's four-ramp partial cloverleaf interchange with
I-25 and
US 87 a short distance to the east. I-80 BL and US 30 intersect Missile Drive, cross Crow Creek, and have an at-grade crossing of a
BNSF Railway line before entering downtown Cheyenne. In the center of downtown, north of the Cheyenne railyard and the
Cheyenne Depot Museum, the highways intersect
US 85,
I-25 Bus, and the northern end of
I-180. Those north–south highways use Central Avenue southbound and Warren Avenue northbound. I-80 BL and US 30 leave downtown Cheyenne and the vicinity of the railroad as they pass Holiday Park. On the east side of Cheyenne at Lincolnway's intersection with
WYO 212 (College Drive), US 30 continues east and I-80 BL turns south onto WYO 212. The business route and state highway cross over Union Pacific Railroad's

business loop in the US state of
Wyoming. It serves as a loop through
Pine Bluffs, near
I-80 and traverses approximately . Concurrent highway routing in the Pine Bluffs area is along
US 30 (including Parsons Street). Previous concurrent routing included US 30 and
State Link 53B (L-53B) in Nebraska. All signs and references to the business loop in Nebraska were completely removed in 2009, due to a decommissioning of all such related Interstate routes statewide. Business route shields were removed on the Wyoming side around the same time but were reinstalled in places along the route in Pine Bluffs in 2012. ==Nebraska==
