State Trunk Highway 118 (often called Highway 118, STH-118 or WIS 118) is a 6.86miles state highway in the U.S. state of Wisconsin. It runs from U.S. Route 63 east of Benoit east to Wisconsin Highway 112 south of Ashland. The highway is located in Bayfield and Ashland Counties in northwest Wisconsin. Highway 118 is maintained by the Wisconsin Department of Transportation.
Highway 118 begins at an intersection with US 63 and County Highway F east of Benoit. The intersection is located at the quadripoint of four towns; the Town of Eileen, Town of Kelly, Town of Keystone and Town of Mason. From here, Highway 118 heads east along the border of the Town of Eileen and the Town of Kelly. The route runs through a rural area, passing numerous farms. The White River runs to the south of the highway for most of its length, coming closer to the road in the east. After crossing into Ashland County, the highway follows the border between the Town of Gingles and Town of White River. It curves slightly before terminating at a junction with Highway 112. The highway is an undivided two-lane road for its entire length.[2] [3]
