Wyoming Highway 270

Wyoming Highway 270 starts at its southern end in Platte County at US 26 on the eastern edge of Guernsey. From here Highway 270 heads north as Hartville Highway on its way to the town of the same name. WYO 270 reaches Hartville at approximately 4.5 miles, and intersects the western terminus of Wyoming Highway 318 (Main Street).[1] Wyoming Highway 270 continues north, leaving Hartville to head north to Manville and Lance Creek.[2] At almost 40 miles, WYO 270 intersects US 18/US 20 just before entering Manville. Upon entering Manville, the former Wyoming Highway 274 (9th Avenue) is intersected. Highway 274 was designated for the old alignment of US 18/US 20, but was decommissioned in the early 1990s.[2]

North of Manville, Highway 270 heads to Lance Creek and intersects the eastern terminus of Wyoming Highway 271 (Twentymile Road).[1] Wyoming Highway 270 then begins to turn east as the last length of its routing is primarily east–west. Wyoming Highway 272 (N. Lance Creek Road) is intersected at just under 61 miles. At just over 73 miles, WYO 270 reaches its northern (or eastern) end at US 18/US 85 north of Lusk.[1][2]
