State Trunk Highway29 (often called Highway29, STH-29 or WIS29) is a state highway running east–west across central Wisconsin. It is a major east–west corridor connecting the Twin Cities and the Chippewa Valley with Wausau and Green Bay. A multi-year project to convert the corridor to a four-lane freeway or expressway from Elk Mound to Green Bay was completed in 2005. The remainder of WIS29 is two-lane surface road or an urban multi-lane road.

Route description

Prescott to Elk Mound

WIS29 begins at its western terminus at U.S. Highway 10 (US10), on the north side of Prescott. From this point, WIS29 is concurrent with WIS 35 going northeast to River Falls, passing the University of Wisconsin–River Falls campus. At the junction with WIS 65, WIS35 turns northbound with WIS65 while WIS29 continues east. WIS29 joins briefly with US 63 west of Spring Valley and turns eastbound upon its split south to head into Spring Valley. Upon leaving Spring Valley and Pierce County, Wisconsin, the highway heads northwardward into St. Croix County and turns east towards Menomonie. WIS29 does not pass through any municipalities while in this county, but it does cross WIS 128.

Upon entering Dunn County, the route passes through rural terrain and enters Menomonie's west side as Hudson Road. The highway turns northward onto Main Street and passes west and north of the University of Wisconsin–Stout campus. WIS29 turns east onto Stout Road along with US 12 and leaves the city to the east. US12/WIS29 proceeds east for about and junctions with Interstate 94 (I-94). This interchange is the westernmost point of the multi-lane WIS29 corridor. It is also the westernmost point of WIS29 as a backbone route in Corridors 2020.

Elk Mound to Wausau

West of County Highway T (CTH-T), the highway is an expressway. It passes into the Chippewa Valley metropolitan area and south of Chippewa Falls as a freeway and crosses US 53 at a cloverleaf interchange in Lake Hallie. WIS29 junctions with the southern terminus of WIS 178 southeast of Chippewa Falls then passes to the south of Lake Wissota State Park before crossing under WIS 27 in Cadott. WIS29 passes south of Boyd and Stanley before exiting the county to the east.

In Clark County, WIS29 meets WIS 73 in Thorp. The two highways run concurrently and exit the village to the east, and WIS73 splits to the south in Withee about east. WIS29 continues east and passes south of Owen and Curtiss. At Abbotsford, WIS29 and WIS 13 meet at a partial cloverleaf interchange between Abbotsford and Colby on the Clark–Marathon county line. east of Abbotsford, WIS29 and WIS 97 meet at a diamond interchange. This is a key route for travelers between Wausau and Marshfield. East of this junction, WIS29 follows a straight course that passes Edgar and meets WIS 107 at a diamond interchange on the north side of Marathon City, approximately west of Wausau. WIS29 enters Wausau as a freeway, junctions with Stewart Avenue approximately west of US 51 at an eastbound off/westbound on style half-interchange. WIS29 then immediately enters the US51 interchange, and turns south onto and follows US51 for , bypassing the downtown area to the south.

Wausau to Green Bay

South of Wausau, WIS29 turns off US 51 to the east at the northern terminus of I-39 and continues as freeway, passing through the villages of Rothschild and Weston. The freeway section ends at Ringle. As an expressway, the highway passes just south of Hatley and turns southeast for about four miles (6km) before turning east again at the northern terminus of WIS 49.

The highway enters Shawano County about east of this junction. WIS29 passes north and around Wittenberg. US 45 joins with the highway north of Wittenberg and the two routes run concurrently to where US45 splits to the south at about east of the village. WIS29 bypasses Tilleda and Thornton on the way towards Shawano. At Shawano, the expressway becomes a freeway at the junction with CTH-MMM (WIS29 Business) and turns southeast to bypass Shawano to the south, diamond interchanges link the highway with WIS 22 and WIS 47 north/WIS 55 north as it pass south of the city. WIS47 south and WIS55 south follow WIS29 east. WIS47 splits to the south at the diamond interchange junction with WIS 117 south of Bonduel. WIS29 (along with WIS55) then returns to an expressway at the junction with CTH-BE (WIS29's former route). WIS55 splits to the south at the diamond interchange junction with WIS 160 at Angelica and WIS29 heads southeast to the Brown County line.

About into Brown County, WIS29 collects WIS 32 eastbound at the diamond interchange with WIS 156 and CTH-Y. WIS29 very briefly passes through the northeast corner of Outagamie County and enters the village of Howard. The multilane expressway and the Backbone Corridor route end at Interstate 41/US 41. WIS32 turns south onto I-41/US41 as WIS29 continues into Green Bay as Shawano Avenue.

Green Bay to Kewaunee

In downtown Green Bay, WIS29 turns north onto South Monroe Avenue for four blocks, joining with WIS 54 and turns east onto Main Street, splitting from WIS54 and joining US 141 to leave the city to the southeast. The highways pass over I-43 without an interchange. WIS29 splits to the east from US141 at about north of US's southern terminus at I-43 in Bellevue. This provides the only access from I-43 to WIS29. The highway passes through Poland and Henrysville as it exits Brown County to the east. In Kewaunee County, WIS29 passes due east through Pilsen and north of Krok as a two-lane road. The highway ends in downtown Kewaunee at WIS 42 on the shores of Lake Michigan.

History

Prior to 1926, WIS29 was numbered WIS116 from Minnesota to Chippewa Falls, WIS16 from Chippewa Falls to Bellevue, and WIS146 from Bellevue to Kewaunee. WIS16 continued southeast from Bellevue along what became US 141 in 1926 to Manitowoc. What had been WIS29 before 1926 became US 16 across the state.

WIS29 has long been known as "Bloody29" because of the prevalence of grisly fatal traffic crashes along significant portions of the highway. In 1988, a study was commissioned to examine widening the highway to a four-lane divided highway. The changes would be made along of road from I-94, west of Elk Mound, to US41 in Howard (suburban Green Bay). The final segment of the highway, connecting the east side of Chippewa Falls with the segment running north of Eau Claire, was opened to traffic on August 16, 2005. Of the total length, about of the highway meets Interstate Highway standards. Most of the expansion was completed with only minor additions to the already-existing easements, and as a result, the expanded roadway almost exactly matches the highway's original course.

A project expanding WIS29 and reconfiguring interchanges with US 51 and I-39 in the Wausau area was completed in 2010 at a cost of $309 million. Based on the high cost and limited benefits, this project was included in WisPIRGss list of highway boondoggles.

The portion of WIS29 between Chippewa Falls and Abbotsford roughly follows what used to be the Yellowstone Trail.

Before 2025 WIS29 had a junction with WIS52 on Stewart Avenue, however WIS52 now runs on Bridge Street avoiding WIS29.

In the 2020s, the WIS29 corridor from Green Bay to Eau Claire was designated as an Alternative Fuel Corridor for electric vehicles.

Future

Long range plans call for WIS29 to be converted to a full freeway between I-94 in Elk Mound and I-41 in Green Bay, however, there is no timetable for the entire corridor to be completed.
