 The highway ends at US 2 and US 53 southeast of Superior.With some variation due to realignments over time, the original 1918 routing this highway followed much of today's STH 13, beginning at what was then Kilbourn (present-day Wisconsin Dells), travelling north through Adams, Grand Rapids (now Wisconsin Rapids), Marshfield, Prentice and Ashland, ending in Bayfield.It was later that STH 13 was routed around the Bayfield Peninsula and westerly to just before Superior.
