STATE ROUTE DESCRIPTION COUNTY MILEAGE NAMING
Routing: Wyoming 210 travels from Interstate 80 and U.S. 30 (Exit 323) at the Sherman Hill Summit and Lincoln Memorial Rest Area east to Interstate 25 and U.S. 87 (Exit 10) in Cheyenne via Curt Gowdy State Park and the Pole Mountain unit of the Medicine Bow National Forest. Mileposts: 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. Guide: Wyoming 210 travels through the rugged scenery of the Pole Mountain area adjacent to Vedauwoo. Some of the region's best rock climbing is found in this area, near the summit area. There used to be a ski area here (Happy Jack Ski Area), but it closed due to a lack of consistent snow. 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. Laramie, Albany 37.33 Happy Jack Road
Routing: Wyoming 211 travels from Wyoming 219 (Old U.S. 85-87) north of Cheyenne (near Interstate 25 and U.S. 85-87, Exit 16) northwest through Iron Mountain, Federal, Horse Creek, and Lambert before reconnecting to Interstate 25 and U.S. 87 near Chugwater. Wyoming 211 has a 20-mile route gap between Milepost 42.94 and at Milepost 63.01; an unpaved county route makes the connection. The section of Wyoming 211 in Platte County Line follows Iron Mountain Road and Jordan Road (County Route 106-2) from Iron Mountain via Diamond. The northern section of Wyoming 211 was previously known as Wyoming 322. Mileposts: Wyoming 212 begins at Milepost 0.00 at its junction with Wyoming 219 (Milepost 4.01). At Milepost 0.51 its meets Interstate 25 and U.S. 85-87 (MP 16.23), then meets former Wyoming 222 at Milepost 3.80. The route temporarily ends at Milepost 42.94 and resumes at Milepost 63.01. The town of Chugwater is at Milepost 63.03, and it meets Interstate 25, U.S. 87, Business Loop I-25, Business U.S. 87, and Wyoming 321 at Milepost 63.95. This interchange (Exit 57) marks the northern terminus of Wyoming 211. Laramie, Platte 43.88 Horse Creek Road; Iron Mountain Road
Routing: Wyoming 212 is College Drive, traveling from Interstate 25 and U.S. 87 Exit 7 east and north around Cheyenne, then west along Four Mile Road west to Wyoming 219 (Old U.S. 85-87 and Old Yellowstone Highway) north of Cheyenne. For the first two miles (between Interstate 25 and U.S. 85/Central Avenue), Wyoming 212 is concurrent with Business Loop I-25 and Business U.S. 87. Between the Interstate 80 interchange and U.S. 30 (Lincolnway), Wyoming 212 is concurrent with Business Loop I-80. Guide: Wyoming 212 begins at Milepost 0.00 at its junction with Interstate 25 and U.S. 87 (MP 7.85), which is adjacent to a State of Wyoming Information Center. Business Loop I-25 and Business U.S. 87 is cosigned with Wyoming 212 for this initial stretch. At Milepost 2.71 is the junction with Greeley Highway, U.S. 85 (P-25, MP 7.31). At this intersection, Business Loop I-25 and Business U.S. 87 turn north along U.S. 85. Wyoming 212 continues alone from here, meeting Wyoming 221 (Fox Farm Road) at Milepost 5.09 and Interstate 80 at Milepost 5.62 at the Sun Valley Interchange (MP 364.00). From this interchange north to Milepost 6.88 (Junction U.S. 30, P-56, MP 365.23), Business Loop I-80 is merged with Wyoming 212. The route ends at Milepost 13.57, which is the junction between Wyoming 212 and Wyoming 219 (MP 2.00). Laramie 13.57 College Drive; Four Mile Road

STATE ROUTE DESCRIPTION COUNTY MILEAGE NAMING
Routing: Wyoming 213 travels from Interstate 80 and U.S. 30 Exit 386 north through Burns to U.S. 85 in Laramie County. Until 2009, Wyoming 213 only connected Interstate 80 with Burns, while the route north to U.S. 85 was a county-maintained road. The final configuration of Wyoming 213 will include a bypass that runs east of Burns with a new railroad crossing. For now, however, Wyoming 213 passes through downtown Burns, where the connection for Wyoming 213 is knowing as Main Street. Within downtown Burns, Wyoming 213/Main Street is maintained locally, as Main Street is divided by an elongated park-like median and is not built to state highway standards. Crossing the railroad tracks north of downtown Burns, Wyoming 213 meets Laramie County Route 148 (which travels west) and former Laramie County Route 149. At this intersection, Wyoming 213 curves east onto former Laramie County Route 149, which turns north after paralleling the railroad tracks. The extension of Wyoming 213 north absorbed former Laramie County 149 (Burns Road North) north to U.S. 85 in 2009. Mileposts: Milepost 0.00 is at Junction Interstate 80 and U.S. 30 (MP 386.39) and Wyoming 214 (MP 0.00). It enters Burns at Milepost 2.11, and it used to end at Milepost 2.61. Laramie approx 19 miles Burns Road
Routing: Wyoming 214 travels from Interstate 80 and U.S. 30 Exit 386 south to Laramie County Route 203-1 (Chalk Bluffs Road) in Carpenter. The highway continues north of Interstate 80 as Wyoming 213 and previously linked to former Colorado 155. Mileposts: Milepost 0.00 is at the junction with Interstate 80 and U.S. 30 (MP 386.39) and Wyoming 213 (MP 0.00). The mileposts increase from north to south, and it enters Carpenter at Milepost 8.33. The state route ends a short distance thereafter, at Milepost 8.39. Laramie 8.39 Carpenter Road
Routing: Wyoming 215 travels from Business Loop I-80 and Business U.S. 30 in Pine Bluffs north to Wyoming 216 near Albin. North of Albin, continues as Laramie County 162-2 north to Wyoming 151 near La Grange. Mileposts: The state highway begins at Milepost 0.00 at its junction with Business Loop I-80 and U.S. 30 (MP 401.52), and it crosses over a Union Pacific Railroad Separation at Milepost 0.22. A realignment is accounted for at Milepost 0.93BK=0.88AH, and Wyoming 215 leaves Pine Bluffs at Milepost 1.80. It ends at its junction with Wyoming 216 at Milepost 17.14. Laramie 17.19 Highway 215
Routing: Wyoming 216 travels from U.S. 85 (P-25; MP 43.02) twenty-six miles northeast of the Interstate 25/U.S. 85 split east to Laramie County Route 164-3 (State Line Road) east of Albin, ending at the Wyoming-Nebraska State Line. Wyoming 216 connects to Wyoming 215, which travels south to U.S. 30 in Pine Bluffs. Mileposts: Wyoming 216 begins at Milepost 0.00 at its junction with U.S. 85 (P-25, MP 43.02), passes through Albin between Mileposts 15.83 and 16.18, and it meets Wyoming 215 at Milepost 16.47. Wyoming 216 ends at the Nebraska State Line at Milepost 18.54. Laramie 18.54 Albin Road
History: A historical routing of Wyoming 216 was created in 1926, the same year U.S. 16 and Wyoming 116 were created. Although it began life as a state route, it was quickly recommissioned as U.S. 216. However, in 1936, U.S. 216 was recommissioned as part of U.S. 16, and the 216 designation was deleted. Weston, Crook N/A -
History: Wyoming 217 was formerly the state highway from Hillsdale south to Crow Creek with an interchange at Interstate 80 and U.S. 30 Exit 377. Mileposts: Milepost 0.00 was at Interstate 80 (MP 377.35)/Hillsdale Interchange. There is a small milepost equation (MP 0.07BK=0.06AH), and the route ended at Milepost 4.42 for a total distance of 4.43 miles. The route was decommissioned in 2009; all state route marker signs have been removed, and the route no longer appears on the Wyoming Official State Highway Map. Laramie 4.43 -
History: Wyoming 218 was formerly the state highway from Interstate 80 and U.S. 30 Exit 342 south to the town of Harriman and the Union Pacific Railroad. Today, all of Harriman Road is a Laramie County maintained route until entering Colorado, where it becomes a Larimer County maintained route all the way to its junction with U.S. 287 south of Virginia Dale. Most of the Wyoming portion of this county route is unpaved. Mileposts: The mileposts used to increase from north to south, but the previously state-maintained portion only went for 1.77 miles. The route was decommissioned in 2009; all state route marker signs have been removed, and the route no longer appears on the Wyoming Official State Highway Map. Laramie approx 2 miles Harriman Road
Routing: Wyoming 219 is old U.S. 85-87 north of Chyenne. It travels from Business Loop I-25, U.S. 85, and Business U.S. 87 (Central Avenue) north to U.S. 85 near Interstate 25 Exit 17. Portions of the route serve as a frontage road. The highway continues north of its northern terminus as Laramie County Route 124-2 (Old Yellowstone Road), which continues north to the Platte-Laramie County Line. Mileposts: Wyoming 219 begins with its zero milepost at Junction Business Loop I-25, U.S. 85, and U.S. 87 (P-25, MP 11.79). At Milepost 0.25, the divided highway ends. The northern city limits of Cheyenne at at Milepost 1.35, and Wyoming DOT begins its maintenance at Milepost 1.99. At Milepost 2.00, Wyoming 219 meets Wyoming 212 (Four Mile Road), and it meets Wyoming 211 at Milepost 4.00BK=4.01AH. At Milepost 5.49, the route comes to its end at Junction U.S. 85 (P-25; MP 17.65). Laramie 5.48 Yellowstone Road
Routing: Wyoming 220 travels from U.S. 287 and Wyoming 789 at Muddy Gap Junction northeast to Interstate 25 and U.S. 20-26-87 in Casper. Guide: Wyoming 220 lies along the historic Oregon Trail. Independence Rock, a famous resting stop known as "The Great Register of the Desert," is located along Wyoming 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. At the western end of the route, Wyoming 220 curves south onto U.S. 287 and Wyoming 789 south at Muddy Gap. The Oregon Trail continues northwest via U.S. 287 and Wyoming 789 north. The Pathfinder and Alcova Reservoirs are also along Wyoming 220; both of these resevoirs 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 Bessemer Bends, which was a popular place for Oregon Trail wagoneers to cross the North Platte due to its shallow level in this area. Once in the city of Casper and northeast of Wyoming 258/Wyoming Boulevard, portions of the route are city maintained but are signed for route continuity purposes. History: Between 1926 and 1938, what is now Wyoming 220 was part of U.S. 87E. In 1938, U.S. 87E was renamed as Wyoming 220. There have only been a few routing changes for Wyoming 220 since then, except that it was connected to Interstate 25 when the freeway was completed through Casper. Carbon, Natrona 72.79 Alcova Highway
History: Wyoming 221 used to follow Fox Farm Road from Business Loop I-25, U.S. 85, and Business U.S. 87 (Central Avenue/Greeley Highway) east to Wyoming 212 (College Avenue). Wyoming 221 was 1.84 miles long. This east-west route paralleled Interstate 80 about one-half mile south of the Interstate. The route was decommissioned in 2009; all state route marker signs have been removed, and the route no longer appears on the Wyoming Official State Highway Map. Laramie 1.84 Fox Farm Road
Routing: Wyoming 222 travels from Wyoming 225/Otto Road (Old U.S. 30 west of Cheyenne) north to Wyomingn 210/Happy Jack Road. F.E. Warren Air Force Base (Randall Avenue). Mileposts: Milepost 0.00 is the southern terminus of this route at Junction Wyoming 225, Otto Road (MP 358.01). The Interstate 80 (Round Top) Interchange is at Milepost 0.79. At Milepost 1.81, Wyoming 222 intersects Wyoming 210/Happy Jack Road (MP 2.94). The segment of Wyoming 222 north of Wyoming 210 used to be in the state highway system, but it has since been decommissioned. Prior to Wyoming 221's retraction, Wyoming 221 used to meet the F.E. Warren Air Force Base Boundary at Milepost 2.08, and Wyoming DOT maintenance used to end at Milepost 4.07. This former section of state highway used to end at Milepost 8.29 at its junction with Wyoming 211 (MP 3.80). Laramie 1.81 Fort Access Road
Routing: Wyoming 223 travels from Interstate 25 Exit 2 east to U.S. 85 (Greeley Highway) south of Cheyenne. Westbound, this route is signed as "To Interstate 25." Milepost 0.00 is at Junction Interstate 25 (MP 2.66). There is a Union Pacific Railroad Separation at Milepost 0.86, and the route ends at its junction with U.S. 85 (P-25, MP 4.12) at Milepost 5.69. Wyoming 223 is an old alignment of U.S. 87. Laramie 5.69 Terry Ranch Road
Routing: Wyoming 224 travels from Interstate 25/U.S. 87 and Business Loop I-25 and U.S. 85-87B/Central Avenue west to the Wyoming Department of Transportation Headquarters and the Wyoming Department of Fish & Game offices. Traveling north on Business Loop I-25, U.S. 85, and Business U.S. 87 (Central Avenue), Wyoming 224 begins upon crossing over Interstate 25 and proceeding straight ahead on Central Avenue for the last quarter of a mile. Wyoming 224 is not signed. Mileposts: Milepost 0.00 is the junction with Interstate 25 (MP 12.70) and Business Loop I-25, U.S. 85, and Business U.S. 87 (P-25, MP 12.61). The Wyoming Department of Fish and Game Headquarters is at Milepost 0.05, and the Wyoming Department of Ttransportation entrance is at Milepost 0.06. The main visitors parking area in the entrance is at Milepost 0.07, and other parking areas are at Milepost 0.09. The route ends at Milepost 0.12 at F.E. Warren Air Force Base, which also provides golf course access. Laramie 0.12 Wyoming Department of Transportation Headquarters Entrance
Routing: Wyoming 225 travels from Interstate 80 and U.S. 30 Exit 348 to Interstate 80 and U.S. 30 Exit 358 (West Lincolnway; west Cheyenne business loop). Mileposts: The mileposts on Wyoming 225 are based on U.S. 30, so they begin with Milepost 348.36 at its junction with Interstate 80 and U.S. 30 (MP 348.36). 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. History: Wyoming 225 is a portion of the original U.S. 30 route before Interstate 80 was built and the U.S. 30 designation transferred to the freeway. 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 (with some abandoned segments of old U.S. 30 visible yet inaccessible from Interstate 80). Laramie 11.21 Otto Road
History: Wyoming 226 used to follow Missile Drive, which is now part of Wyoming 210. When Wyoming 210 used to follow the Old Happy Jack Road alignment, it did not intersect Interstate 25 and ended at Business Loop I-80 (Lincolnway). To alleviate this problem, Wyoming 210 was routed over Missile Drive and now ends at Interstate 25. Prior to this rerouting, Missile Drive was designated as Wyoming 226. Laramie approx 1 mile Missile Drive

Routing: Wyoming 230 has two segments. The western segment travels from Wyoming 130 just south of Saratoga southeast to the Colorado-Wyoming state line via Riverside near Encampment in Carbon County. Wyoming 230 resumes in Albany County, emerging from Colorado-Wyoming state line, then turning northeast toward Laramie, ending at Business Loop I-80 and U.S. 30-287/Third Street near downtown Laramie. The implied connection between the two segments is achieved via Colorado 125 and Colorado 127 through Three Way. Notably, the last four miles of this route are on a shared alignment with Wyoming 130 (via Snowy Range Road); this is one of the rare cases where two state routes overlap in Wyoming. The mileage of 78.74 excludes the Colorado mileage via Colorado 125 and 127.

Guide: Leaving the vicinity of Saratoga in the Platte Valley, Wyoming 230 slowly climbs out of the Platte Valley to a crest of over 8,000 feet above sea level. Wyoming 230 passes several ranches before entering Colorado. Once in Colorado, Wyoming 230 changes into Colorado 125 and meets Colorado 127 at Three Way. To reconnect to Wyoming 230, turn northeast on Colorado 127 back to the state line (or proceed south on Colorado 125 to Walden). Upon reentering the state, Wyoming 230 climbs into the southeastern edge of the Snowy Range Mountains, passing near the forested lands near Fox Park and Woods Landing. Jelm Mountain, home of the University of Wyoming observatory, is located just off Wyoming 230 (via Wyoming 10). From the Jelm Mountain area, Wyoming 230 descends into the Laramie Basin and eventually meets Wyoming 130 on the western edge of Laramie. The two state routes continue together on a shared alignment into Laramie as Snowy Range Road. After an interchange with Interstate 80, Wyoming 130-230 serve the main entrance into Wyoming Territorial Prison State Historic Site.

History: Wyoming 274 was the designation for the old alignment of U.S. 18-20 through Manville in Niobrara County after a bypass route was built to avoid downtown 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 Wyoming 274. Wyoming 274 was the new designation of the original U.S. 18-20 through this area, until WyoDOT relinquished control of Wyoming 274 in the early 1990s. With that action, Wyoming 274 was decommissioned. Niobrara Approx 1.5 miles Country Club Road
History: Wyoming 287 had three historical definitions, none of which are known as Wyoming 287 today. However, one routing is now part of U.S. 287. In 1926, Wyoming 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, Wyoming 287 was extended south to U.S. 30S near Piedmont. In 1936, the year of the Great Recommissioning of U.S. routes, Wyoming 287 was recommissioned as U.S. 89. U.S. 287 appeared in 1936, so the Wyoming 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 Wyoming 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 Wyoming 287 and U.S. 287 were switched: the U.S. route would take the more direct route from Lander to Diversion Dam Junction, while Wyoming 320 took over the Lander to Riverton section of old U.S. 287. Wyoming 287 was the remainder of the route from Riverton to Diversion Dam Junction. In 1950, Wyoming 287 was eliminated with the extension of U.S. 26. Wyoming 320 followed suit in 1954 when Wyoming 789 was commissioned. Fremont N/A U.S. 287

Park 9.00 Clarks Fork Canyon Road
History: Wyoming 292 was a state route that used to travel from Wyoming 120 near the Wyoming 120-294 junction southwest to Clark and the Clarks Fork River. This route is now called Clarks Fork Canyon Road. Research shows this highway on a 1966 and 1979 official state maps, but it was no longer a state highway by the 1990s.
