Wisconsin Highway 70

The highway begins at a bridge over the St. Croix River as a continuation of MN 70, running east from it. At Grantsburg, the highway intersects WIS 87/WIS 48. The highway continues east from there, curving slightly south to avoid Mud Hen Lake before running northeast to meet WIS 35 in Siren. It then runs concurrently with WIS 35, running north from Siren before leaving the concurrency at a roundabout. The highway then runs east, passing through intersections with County Trunk Highway X (CTH-X), CTH-H, and CTH-O. It then passes through an intersection with US 63 in Spooner and an interchange with US 53 east of Spooner. In Woodruff, the highway intersects WIS 47 and leaves the US 51 concurrency in Arbor Vitae, Wisconsin. It then runs east, intersecting with WIS 155 before following the Wisconsin River to Eagle River, where it runs concurrently with US 45. It then enters the Headwaters Wilderness, intersecting WIS 55 and running concurrently with WIS 139 within it. After exiting the wilderness, the highway continues east, intersecting and running concurrently with WIS 101 before terminating at US 2 in Florence. ==History==
