U.S. Highway 51 (US 51) in the U.S. state of Wisconsin runs north–south down the central part of the state. It enters from Illinois at Beloit, and runs north to its northern terminus in Hurley where it junctions with US 2. Much of the route of US 51 runs concurrently with Interstate 39 (I-39).
From Beloit, US 51 passes through Janesville and Edgerton. 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 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. North of Madison, US 51 parallels the Interstates on the east side passing through De Forest, Leeds, North Leeds, Poynette and Portage. 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. The route joins I-39 north of Portage. There is a short concurrency with WIS 23 from Endeavor to WIS 82 near Oxford. They stay joined until I-39 ends at WIS 29. 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. Proceeding north from Stevens Point, the highway bypasses Knowlton, Mosinee, and Rothschild where I-39 terminates at the WIS 29 east interchange. 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. US 51 continues as a freeway to Merrill, passing Brokaw along the way.
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. 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. This will eventually be converted to a freeway, making US 51 a continuous freeway from Portage to Tomahawk.
The freeway in the Wausau area was not originally fully up to Interstate standards, but a project to upgrade the freeway to full standards in the area was recently completed.[when?] The upgrades in the Wausau area replaced all of the existing 1963-era low clearance overpasses; upgraded the WIS 29 east, CTH-N, CTH-NN, Sherman Street, WIS 52, and Bridge Street interchanges; and constructed a free-flow interchange for WIS 29 west.
The highway becomes a two-lane road just north of US 8 at the Oneida County line. The highway passes through Minocqua, Manitowish Waters, and Mercer on its northwest trek toward Hurley and its terminus at a junction with US 2.
Prior to 1926, what is now US 51 was State Trunk Highway 10.
US 51 was upgraded to a full freeway over a period of 25 years from Merrill to Portage. The freeway continues around Portage to the west as I-39 (originally as WIS 78) to connect with I-90 and I-94 while US 51 continues along surface roads into and through Portage. In the 1990s, US 51 was designated as I-39 from its junction with WIS 29 eastbound in Wausau to where it left the freeway at exit 92 in Portage. US 51 remained cosigned with I-39 along this entire stretch of road. Further expansion of the highway northward took place in 2000, when the highway was upgraded to an expressway up to CTH-S. In addition, a super-two freeway from CTH-S to US 8 was upgraded to a four-lane freeway.
The Wisconsin mileage of US 51 is designated by the state as the Korean War Veterans Memorial Highway.
