Highway102 begins at Sistonens Corners, immediately south of a Canadian National Railway (CN) overpass, along Highway11 and Highway17. A truck stop sits to the west of the intersection. From there, the two-lane road travels east through rolling hills, with muskeg dotting the valleys between the hills. It parallels roughly to the south of the Shebandowan River for before crossing both the CN and Canadian Pacific Railway tracks as well as the Kaministiquia River. The highway meets Silver Falls Road, which proceeds north to Silver Falls Provincial Park. The terrain becomes gentler as the route passes several houses while travelling alongside a creek. The highway curves as it meets a power transmission line, which it then parallels. It zig-zags southeast, passing alongside Mud Lake and briefly curving back to the east. Curving back to the southeast, the highway serves several houses before crossing into Thunder Bay at Townline Road and curving to the east.
