Wisconsin Highway 42 - Route Description

Route Description

WIS 42 begins at the intersection of North 14th Street and Erie Avenue (also known as Kohler Memorial Drive) in downtown Sheboygan, a block north of the bridge crossing the Sheboygan River. The intersection is the terminus of two other state highways: WIS 23 and WIS 28.

WIS 42 follows North 14th Street to Calumet Drive, which heads out of the city in a northwesterly direction to its interchange with Interstate 43 (exit 128). The route continues to the northwest into the city of Howards Grove, where it becomes Madison Avenue.

At the intersection of Madison Avenue and South Wisconsin Drive, WIS 42 and WIS 32 meet. WIS 32 continues to the northwest on Madison Avenue, while WIS 42 turns north on Wisconsin Drive. WIS 42 continues north out of Howards Grove into Manitowoc County.

WIS 42 continues to the north towards the city of Manitowoc, where it intersects with US 151 (Calumet Avenue), just west of I-43. Turning east, WIS 42 runs concurrent with US 151 for about a quarter mile before turning onto I-43 at exit 149. WIS 42 formerly ran east beyond the interchange with I-43 to South Rapids Road, following the road to the north to Waldo Boulevard and US 10 on the north side of Manitowoc. WIS 42 now runs north on I-43 to its interchange with CTH JJ (exit number 152).

WIS 42 and US 10 follow Waldo Boulevard to the shore of Lake Michigan, running northeast along the shoreline on Memorial Drive out of the city and into Two Rivers.

Crossing the West Twin River near its confluence with the East Twin River just south of downtown Two Rivers, WIS 42 becomes Washington Street. Two blocks north, it meets the eastern terminus of WIS 310 at 16th Street. Six blocks north, it meets the eastern terminus of WIS 147 at 22nd Street.

WIS 42 turns to the east on 22nd Street and crosses over the East Twin River, then turns north on Lincoln Avenue. WIS 42 and WIS 147 are the only two state highways that cross both branches of the Twin Rivers, though WIS 147 does not cross the West Twin River until about a mile east of its terminus with I-43 near Maribel.

WIS 42 continues to the north, running roughly parallel to the Lake Michigan shoreline into Kewaunee County. Just south of the city of Kewaunee, WIS 42 turns east on Krok Road to Lakeshore Drive, where it turns north and heads into the city as Milwaukee Street.

In downtown Kewaunee, WIS 42 meets the eastern terminus of another state highway, WIS 29. WIS 42 becomes Main Street after crossing the Kewaunee River and continues north out of the city.

In the unincorporated town of Alaska, WIS 42 again turns east towards Lake Michigan to follow the shoreline into Algoma as Lake Street. In downtown Algoma, WIS 42 turns north onto 4th Street and crosses the Ahnapee River. On the north bank of the river, WIS 42 turns northwest onto North Water Street and follows the river in a northerly direction to Forestville in Door County, where it becomes Forestville Avenue.
