Montana Highway 86

MT 86 begins at the intersection of Rouse Avenue and East Main Street, which carries US 191, in downtown Bozeman. It heads north on Rouse along a two-lane street through a residential area. In the northern part of town, MT 86 crosses the Montana Rail Link while simultaneously passing beneath Interstate 90. The highway turns to the east and leaves the city; it skirts the southern edge of the Bridger Range. It passes beneath the "College M", a 250-by-100-foot (76 m × 30 m) limestone majuscule M built into the side of Old Baldy within sight of Bozeman and Montana State University.[3] The highway curves around the eastern flank of the mountain range and follows a northerly path.[4]

MT 86 travels through mountainous terrain. Coniferous trees line either side of the road's right-of-way. It passes the Bridger Bowl Ski Area, which lies to the west. Shortly thereafter, it meets Brackett Creek Road, which roughly marks the halfway point of the route. The forest surrounding the highway yields to grassland and the terrain levels somewhat as the road turns to the north-northeast near Sedan. The highway takes a sharp curve to the east and then angles to the northeast. The road ends at US 89 a few miles north of Wilsall.[4]
