From Interstate 25 and U.S. 87 (Exit 10) in Cheyenne west to Interstate 80 and U.S. 30 at the Sherman Hill Summit and Lincoln Memorial Rest Area via Curt Gowdy State Park and the Pole Mountain unit of the Medicine Bow National Forest. Mileposts increase from east to west. Milepost 0.00 is at the junction of Wyoming 210 with Interstate 25 and U.S. 87. It meets Missile Drive at Milepost 0.16 (this is former Wyoming 226). There is a milepost equation at 1.73BK=2.19AH. Wyoming 210 passes by the F.E. Warren Air Force Base Boundary at Milepost 2.19. At Milepost 2.94, it meets Wyoming 222. The Laramie-Albany County Line is at Milepost 25.82, and the boundary for Medicine Bow National Forest is at Milepost 26.45. The route ends at Milepost 37.79, which is the junction of Wyoming 210 with Interstate 80 and U.S. 30 (Exit 323) near the State of Wyoming Information Center. Wyoming 210 through the Pole Mountain area (popularly called Vedauwoo) is incredible, with some of the best rock climbing around. There used to be a ski area here (the Happy Jack Ski Area), but it closed due to a lack of consistent snow. The main problem was that once the snow fell, it would blow away. That's the one constant about Wyoming: The wind never stops blowing. At Curt Gowdy State Park, there are reservoirs that supply water to Cheyenne and Laramie. During the cold winter months, these lakes can freeze solid.

From U.S. 287 and Wyoming 789 at Muddy Gap Junction northeast to Interstate 25 and U.S. 20-26-87 in Casper. Wyoming 220 lies along the famous Oregon Trail. Independence Rock, a famous resting stop known as "The Great Register of the Desert," is located along Wyo. 220 southwest of Casper. Pioneers inscribed their names into the rock, and those names can still be read today. Further west along Wyoming 220 is Devil's Gate, a well-known landmark along the Oregon Trail. The gate is a narrow passageway for the Sweetwater River as it travels the extreme north end of the Red Desert. Wyoming 220 ends just beyond this point; Oregon Trail travelers continue west via U.S. 287 northwest-bound. Between 1926 and 1938, what is now Wyoming 220 was part of U.S. 87E. In 1938, U.S. 87E was renamed Wyoming 220. There have been few routing changes in Wyoming 220 since then, except that it was connected to Interstate 25 when the interstate was completed through Casper. In addition to the Oregon Trail sights along Wyoming 220, the Pathfinder and Alcova Reservoirs are also along this road. Both of these are fed by the North Platte River, which follows Wyoming 220 as it heads into Casper. The drive between the Wyoming 487 junction and Casper is especially scenic, as the North Platte River heads through the Narrows. Near here is the Bessemer Bends, which was a popular place for Oregon Trail wagoneers to cross the North Platte due to its shallow level in this area.

At Milepost 358.01, Wyoming 225 meets Wyoming 222 (MP 0.00), and the divided highway begins at Milepost 359.20. Wyoming 225 ends shortly thereafter, at Milepost 359.55. This is the original U.S. 30 route before Interstate 80 was built and the U.S. 30 designation transferred to the interstate. Most of the remainder of U.S. 30 between Laramie and Cheyenne either (1) has been directly overlaid by the Interstate 80 freeway, (2) serves as a frontage road to Interstate 80, or (3) has been abandoned and fallen into disrepair. This is especially noteworthy when you consider that along the construction project along I-80 and U.S. 30 between Laramie and the Sherman Hill Summit (Pole Mountain / Vedauwoo area), there is no alternate route.

From Wyoming 130 just south of Saratoga southeast to the Colorado-Wyoming State Line via Riverside. Route continues southeast in Colorado as Colorado 125, then it turns northeast as Colorado 127. At the Wyoming-Colorado State Line, Wyoming 230 resumes past Woods Landing to end at Business Loop I-80 and U.S. 30-287 in Laramie. The last four miles of this route are shared with Wyoming 130. This is one of the rare cases where two state routes overlap like this. The mileage of 78.74 excludes the Colorado mileage via Colorado 125 and 127. Wyoming 230 essentially crosses the same type of terrain as Wyoming 130. The section between
south of Saratoga and the Colorado State Line slowly climbs out of the Platte Valley to a crest of
over 8000 feet. Wyoming 230 passes several ranches amid the sagebrush before entering Colorado. Without giving too much away about the Colo. 125-127 section of Wyoming 230, it basically winds down to a junction locally known as "Three Way." Travelers are afforded the choice of continuing south to the small town of Walden (which still has cheaper gas than anywhere in California) or returning to Wyoming. Since Wyoming 230 emerges a few miles to the northeast across the state line, we'll go back into Wyoming. Wyoming 230 climbs again into the southeastern edge of the Snowy Range Mountains. The area around Fox Park and Woods Landing is mostly forested. Hunters regularly come out here in the fall to hunt deer and elk. Jelm Mountain, home of the University of Wyoming observatory, is located just off Wyoming 230. This section of the road, although high, is not closed in winter. In fact, Wyoming 230 provides a scenic, less-traveled alternative for winter travelers who want to avoid Interstate 80 and U.S. 30 but cannot take Wyoming 130 in the winter. Just as the ride starts to get interesting, Wyoming 230 descends into the Laramie Basin. While this portion of the ride is nice in the spring and summer (it gets green!), it is fairly boring. You will see several lakes along this part of the ride; some are reservoirs and others are natural. Fishing is fairly popular in this area. Either way, the drive just drags on. It can be downright awful if you have to go to the bathroom! Wyoming 230 meets Wyoming 130 just west of Laramie, and the two routes continue together into Laramie as Snowy Range Road. This is the only instance in Wyoming where two state routes are merged together.

From U.S. 26 at Guernsey north to Manville and Lance Creek and east to U.S. 18-85 north of Lusk. The mileposts increase from south to north. The mileposts begin at Milepost 495.47 at the Junction with U.S. 26 (P-27, MP 16.55). At Milepost 499.83, the route passes by the southern city limits of Hartville, and it intersects Wyoming 318 at Milepost 500.00. Wyoming 270 leaves Hartvillel at Milepost 500.21, then meets an equation at 522.29BK=523.24AH. It intersects U.S. 18-20 at Milepost 535.87, then has another equation at 535.87BK=99.77AH because Wyoming 270 changes its WyoDOT inventory route number. At Milepost 100.00 it enters Manville at its junction with former Wyoming 274 (Old U.S. 18-20) and leaves Manville at Milepost 100.51. At Milepost 118.09, it meets Wyoming 271 (MP 0.00), and at Milepost 120.86, Wyoming 270 meets Junction Wyoming 272 (MP 0.00). The route ends at Milepost 133.34 at its junction with U.S. 18-85 (P-25 and MP 170.95).

This is old U.S. 18-20 through Manville. Around 1984, old Bypass U.S. 18-20 around Manville became the mainline U.S. 18-20, while old mainline U.S. 18-20 became Wyo. 274. Wyo. 274 was the new designation of the original U.S. 20 through this area, until WyoDOT relinquished control of Wyoming 274 in the early 1990s. With that action, Wyoming 274 was decommissioned. Wyoming 274 was between one and two miles long.

287
Wyoming 287 had three historical definitions, none of which are known as Wyo. 287 today. However, one routing is now part of U.S. 287. In 1926, Wyo. 287 was commissioned along what is now U.S. 189 between U.S. 30N at Kemmerer and U.S. 187 at Daniel Junction. During this time, Wyo. 287 was extended south to U.S. 30S near Piedmont. In 1936, the year of the Great Recommissioning of U.S. routes, Wyo. 287 was recommissioned as U.S. 89. U.S. 287 appeared in 1936, so the Wyo. 287 designation was moved to correspond with that routing. In 1936, U.S. 287 was routed to go through Lander, Riverton, and Diversion Dam Junction on its way to Dubois. The more direct route, from Lander to Diversion Dam Junction, was called Wyo. 287 beginning in 1936. For a point of reference, Diversion Dam Junction is the modern day junction of U.S. 26 and U.S. 287 southeast of Dubois. This routing lasted until 1940, when Wyo. 287 and U.S. 287 were switched: the U.S. route would take the more direct route from Lander to Diversion Dam Junction, while Wyo. 320 took over the Lander to Riverton section of old U.S. 287. Wyo. 287 was the remainder of the route from Riverton to Diversion Dam Junction. In 1950, Wyo. 287 was eliminated with the extension of U.S. 26. Wyo. 320 followed suit in 1954 when Wyo. 789 was commissioned.
