Old Sundance Road
Routing: Wyoming 114 travels from Alternate U.S. 14 in Garland northeast to U.S. 310 and Wyoming 789 in Deaver.
Old Sundance Road
History: Wyoming 114 was once part of U.S. 420 (between 1926 and 1936) and Wyoming 420 (between 1936 and 1939). When U.S. 14 was recommissioned to run through Greybull rather than Lovell and Powell in 1940, Wyoming 14 and Wyoming 114 were born. In the mid-1960s, Wyoming 14 would be recommissioned as Alternate U.S. 14, but Wyoming 114 remained.
Routing: Wyoming 116 is a southwest-northeast state highway that travels from Wyoming 450 northeast to U.S. 16 in Upton, then continues northeast to meet Business Loop I-90 and U.S. 14 in Sundance. This route is signed east-west despite its southwest-northeast orientation.
History: Wyoming 116 has had three major routings between 1926 and today. The first routing of Wyoming 116, commissioned around 1926 and decommissioned in 1936, was related to old U.S. 116. While U.S. 116 ran from U.S. 87E at Sheridan to U.S. 16 Ucross, Wyoming 116 ran from U.S. 310 at Lovell east to U.S. 87E at Ranchester (modern-day U.S. 14A and U.S. 14). The connection would be a short routing along U.S. 87E between Ranchester and Sheridan. Modern-day U.S. 14 between Greybull and Burgess Junction was then known as Wyoming 416. In 1936, U.S. 116, Wyoming 116, and U.S. 420 were recommissioned as U.S. 14, and Wyoming 416 became Wyoming 520. Then in 1940, Wyoming 116 was resurrected to replace Wyoming 316 between Midwest-Edgerton and Gillette via modern day Wyoming 387 and Wyoming 59. This lasted until 1945, when a the current routings of Wyoming 59 and 387 emerged. Several years later, the current routing of Wyoming 116 emerged. It has not changed since it was first commissioned. Wyoming 116 is the only Wyoming x16 route left.
Routing: Wyoming 120 travels northwest from U.S. 20 at Thermopolis to U.S. 14-16-20 in Cody, then turns northeast toward the Montana-Wyoming State Line. At the state line, Wyoming 120 transitions directly into Montana 72 as it turns northeast toward Laurel and U.S. 310.
Hot Springs, Park
History: Wyoming 120 emerged in 1945 to replace Wyoming 420 south of Cody and a new road north of Cody. Wyoming 120 was commissioned to replace Wyoming 420 for three reasons: (1) Wyoming 420 was associated with the old U.S. 420, (2) Wyoming 120 had a different route than Wyoming 420 north of Cody, and (3) the state of Wyoming wanted to use the lowest number (120) available. When Wyoming numbered its state primary routes that were spurs of U.S. routes in the 1920s and 1930s, the state hoped to elevate them to U.S. route status (like Wyoming 216, which became U.S. 216). However, after the Great Recommissioning of 1936, Wyoming started to number its state auxiliary routes from the lowest available number (that is, 120, 220, etc.). This is how U.S. 30, in the 1940s and early 1950s, had child routes Wyoming 130, 230, 330, 430, and 530.
Routing: Wyoming 130 travels from Interstate 80 and U.S. 30-287 at Walcott Junction (Exit 235) south to the Wyoming 230 junction via Saratoga, then turns east across the Snowy Range Mountains through Ryan Park and Centennial to end at Business Loop I-80 and U.S. 30-287 in Laramie. The last four miles of this route at the eastern end are shared with Wyoming 230 (one of the rare instances where two signed state routes share alignment in Wyoming).
Snowy Range Road
History: Wyoming 130 used to begin in downtown Saratoga at the current Wyoming 130/74 junction (this junction is unmarked; it is the corner of First and Bridge Streets). Current Wyoming 130 from the 130/74 junction south to the Wyoming 130/230 junction was old Wyoming 70. The road from Ryan Park to the 130/230 junction was not built at that time. Wyoming 130 traveled southeast along the Carbon County Route 504 path to Ryan Park, then it followed its current path due east to Centennial and Laramie.
Guide: Wyoming 130 can be divided into three distinct sections: Walcott to the split with Wyoming 230 (Platte River Valley and Saratoga), Wyoming 230 to Ryan Park, Libby Flats, and Centennial (across the Snowy Range), and Centennial to Laramie (Laramie Plains). Each of these sections are unique and beautiful in their own right. The Platte River Valley segment of 130 is more typical of the Red Desert environment, with sagebrush covering most of the area and cottonwood trees near the North Platte River. In Saratoga, there are hot springs that have been converted into a public bathing area that is popular year-round, even in blizzards. Once you reach Ryan Park on 130, you are already ascending the Snowy Range (also known as the Medicine Bow Mountains). Ryan Park is home to several cabins and a convenience store. The Medicine Bow Lodge is located here as well.
Silver Lake, Lake Marie, and other alpine lakes line the highway as it ascends the Medicine Bow Mountains, locally known as the Snowy Range. At the top of the Snowy Range, there is a good chance of ice and snow -- the road is closed in the winter due to the heavy snowfall. The view from the top, at Libby Flats, is magnificent. You can see south well into Colorado ... possibly among the best views in the state. Libby Flats marks the Carbon-Albany County line, and Wyoming 130 begins a long descent into the Laramie Basin. Winding down toward Centennial, there are many hiking and cross-country skiing trailheads. A downhill ski area, the Snowy Range Ski Area, is found just west of Centennial. The small community of Centennial has a handful of restaurants, bars, and lodging. There is no town police in Centennial; they rely on the Albany County sheriff. The remainder of the trip may seem boring by comparison, with rolling plains and the mountains in the rear view mirror. In the spring, the hills turn green due to the higher precipitation that time of the year. Notably, there is less sagebrush and more wild grass in the Laramie Plains; this is due to the reduced precipitation.
Routing: Wyoming 131 travels from U.S. 287 (P-15, MP 0.56) in Lander southwest to Sinks Canyon State Park. Mileposts: Mileposts on Wyoming 131 increase from north to south. Milepost 0.00 is at Junction U.S. 287, and the Lander city limits are at Milepost 1.75 (there is a realignment at 0.69BK=0.76AH). The Sinks are at Milepost 7.25, and the highway ends at Milepost 9.00. The Popo Agie River disappears into the ground at Sinks Canyon State Park; it reappears a mile or so downstream. This is known as the Sinks. The first 1.68 miles of Wyoming 131 are maintained by the city of Lander rather than Wyoming DOT according to the 1997 Route Log.

According to the 1995 DeLorme Atlas, Wyoming 176 used to travel about two miles to the northwest and ends. The official highway map of 1970, though, shows it reconnecting with Wyoming Highway 120 about two and a half or three miles west of Thermopolis. The westernmost section of this former state highway appears to have been abandoned and is no longer a through highway. Wyoming 176 might be an old alignment of Wyoming 120.

Grass Creek Road
History: Wyoming 185 is a former designation for the Wyoming 59 corridor north of Douglas. This designation is derivative from the former U.S. 185 designation, which was commissioned in 1926 to run from Cheyenne to Orin. Highway planners proposed this U.S. route continuing north to Gillette, via U.S. 20 between Orin and Douglas, and via Wyoming 59 between Douglas and Gillette. The trouble was, the road now carrying Wyoming 59 had not yet been constructed at that time. So as the road was being constructed in the late 1920s and early 1930s, it carried the designation Wyoming 185. After the Great Recommissioning of 1936, Wyoming 185 was renumbered to Wyoming 387, since the route directly connected to the new U.S. 87, not U.S. 85. It was later changed to Wyoming 59 to match with Montana 59.
Routing: From Wyoming 191 (MP 1.10) at Kaycee west to Barnum. Follows the Middle Fork of the Powder River, and serves the Middle Fork SRMA. Mileposts increase from southeast to northwest. The route starts at Milepost 100.00 at its junction with Wyoming 191, and it ends at Milepost 108.66 with a milepost equation at 107.53BK=107.54AH.
Routing: From Wyoming 196 near Interstate 25/U.S. 87 Exit 254 at Kaycee northwest to Mayoworth. The road continues east of old U.S. 87 (Wyoming 196) as Wyoming 192. Milepost 0.00 is Junction Wyoming 196 (MP 254.08) and Wyoming 192 (MP 0.00). Wyoming 191 meets Interstate 25 and U.S. 87 (MP 254.25) at Milepost 0.16. The route ends at Milepost 11.71 at Mayoworth.
Routing: From Wyoming 196 (Old U.S. 87) near Interstate 25 and U.S. 87 Exit 254 at Kaycee southeast to Wyoming 387 thirteen miles northeast of Edgerton. The road continues to the west of Wyoming 196 (Old U.S. 87) as Wyoming 191. Mileposts increase from west to east, from 0.00 to 35.64.
Routing: From U.S. 87 northwest to Story and then northeast back to U.S. 87 at Banner. The 87/193 junction is northwest of Interstate 90 Exit 44. As a result of a landslide on U.S. 87, Wyoming petitioned AASHTO to reroute U.S. 87 over Wyoming 193 in the late 1990s. This petition was denied. However, a detour for U.S. 87 follows Wyoming 193 since it is unlikely that U.S. 87 will be reconstructed at its current location. the route beginsn with Milepost 100.00 at its junction with U.S. 87 (Wyoming 344) (MP 1.71), crosses the Sheridan-Johnson County Line at Milepost 102.53, meets Junction Wyoming 194 at Milepost 103.92, and has a scenic overlook at Milepost 104.34. The route ends at Milepost 106.19, which is the junction with U.S. 87 (Wyoming 344) (MP 38.90).
Routing: Wyoming 194 travels from Wyoming 193 in Story west to Grandma's Mountain and state fish hatchery. This route is entirely in Sheridan County, so it is an exception to the numbering rule. The Sheridan County numbering scheme indicates this route should be numbered between 330 and 349. Wyoming 194 begins at Milepost 0.00 at its junction with Wyoming 193 (MP 103.92), meets Wyoming 340 (Milepost 0.00) at Milepost 0.59, and ends at Milepost 2.81.
Routing: Wyoming 196 travels from Interstate 25 and U.S. 87 Exit 249 north to Business Loop I-25 and Business U.S. 87 just south of Buffalo near Exit 298. This long state highway used to be part of U.S. 87. Mileposts increase from south to north, and Wyoming 196 carries Old U.S. 87's mileposts. The route begins at Milepost 249.58, which is the junction with Interstate 25 and U.S. 87 at the TTT Interchange (MP 249.69). Wyoming 196 passes through Kaycee between Mileposts 253.69 and 254.00. It meets Wyoming 191 and Wyoming 192 at Milepost 254.08. It passes through the Interstate 25 and U.S. 87 Separation at Milepost 261.43. The route ends at Milepost 299.42, which is junction Business Loop I-25 and Business U.S. 87 south (P-59, MP 298.45) and Business Loop I-25 and Business U.S. 87 north.
History: Wyoming 197 used to travel from Wyoming 192 northeast to Fort Reno, Spreader Dams, and Hoe Ranch along the Powder River. Today this former state highway is now designated as Johnson County Route 110. This route was about seven miles long.
