The highway becomes a two-lane road just north of US 8 at the Oneida County line. This will eventually be converted to a freeway, making US 51 a continuous freeway from Portage to Tomahawk.

In between these freeway segments exists an expressway from Lincoln Drive north of Merrill further north to CTH-S south of Tomahawk with five grade-level intersections. The section of US 51 from Portage at its junction with I-39 to Merrill, as well as from County Trunk Highway S (CTH-S) to US 8 in Tomahawk, is built to Interstate Highway standards. US 51 continues as a freeway to Merrill, passing Brokaw along the way. US 51 continues on with WIS 29 for five miles (8.0 km) bypassing Schofield, then proceeding into Wausau where WIS 29 splits to the west. Proceeding north from Stevens Point, the highway bypasses Knowlton, Mosinee, and Rothschild where I-39 terminates at the WIS 29 east interchange. Along the way, the route bypasses the small communities of Endeavor, Packwaukee, Westfield, Coloma, Hancock, Plainfield, Plover, and Whiting prior to arriving at Stevens Point. They stay joined until I-39 ends at WIS 29. There is a short concurrency with WIS 23 from Endeavor to WIS 82 near Oxford. In North Leeds, US 51 has a major junction with Wisconsin Highway 22 (WIS 22) and WIS 60 where US 51 heads west a bit with WIS 60 before splitting back north toward Poynette. North of Madison, US 51 parallels the Interstates on the east side passing through De Forest, Leeds, North Leeds, Poynette and Portage. US 51 then passes through the east side of Madison as a side route, known locally as Stoughton Road, paralleling to the west of I-39/I-90. US 51 joins with I-39 and I-90 for about five miles (8.0 km) before splitting off and heading west to Stoughton. US 51, along with I-39, in northern Wisconsinįrom Beloit, US 51 passes through Janesville and Edgerton.
