Wyoming Highway 70 is a state highway in southern Wyoming. The route travels from an intersection with Wyoming Highway 789 in Baggs eastward to Wyoming Highway 230 in Riverside. WYO 70 over Battle Pass is closed during winter (November to April). The section of the route within Medicine Bow National Forest is designated the Battle Pass Scenic Byway.
Route description 
Wyoming Highway 70 begins in Baggs at Wyoming Highway 789 and heads east through southern Carbon County near the Colorado state line. Highway 70 travels through the communities of Dixon and Savery before dipping across the state line, where a short section passes through Slater, Colorado (between mileposts 15.34 and 16.24). This short section through Moffat County, Colorado is not part of the Colorado State Highway System, and is maintained by the Wyoming Department of Transportation.  At 16.7 miles, Wyoming 70 intersects with former Colorado State Highway 129, which used to connect US 40 with Wyoming 70. It is now Moffat CR 1. Thereafter the highway travels through very scenic Medicine Bow National Forest (between mileposts 21.25 and 51.10) and passes over Battle Pass at an elevation of 9,955 feet (3,034 m). After leaving the national forest, Highway 70 passes through Encampment and then on to Riverside where it ends at its junction with WYO 230.
During the spring of 2011, a landslide occurred on WYO 70 near milepost 31, about halfway between Baggs and Encampment. The slide destroyed a 1,000-foot length of the highway, and the road was closed to through traffic for several weeks. As a result, a temporary one-lane detour was constructed. Reconstruction of the road where the slide occurred was ruled out after geologic investigations found the slide is likely to continue moving in the future. Work to realign WYO 70 around to the north of the slide area is being done. WYDOT anticipates the realignment project would require two construction seasons, during which time the existing detour would be maintained. 
Between the 1940s and 1960s, Wyoming Highway 70 connected with former Colorado State Highway 129, which used to connect US 40 with Wyoming 70. During the time Highway 129 existed, WY 70 didn't exist as it does now. Only the western part from SH 129 to Baggs was designated as Highway 70. Former Colorado State Highway 129 is now Routt County Route 129.
