Wisconsin Highway 441


State Trunk Highway 441, and often called the Tri-County Expressway or Highway 441 is a state highway in the US state of Wisconsin. Together with Interstate 41/US Highway 41, the highway forms a beltway around the greater Appleton area, and is a freeway for the entire length of its route. It connects at both ends to its parent highway, I-41/US 41. It runs east–west and north–south in east central Wisconsin from near Neenah around Appleton to near Little Chute through Winnebago, Outagamie and Calumet counties. The Roland Kampo Memorial Bridge spans Little Lake Butte des Morts near the highway's southwest terminus.

History

The Roland Kampo Memorial Bridge was the first portion of this road completed; traffic began flowing on the bridge at 11 a.m. on November 30, 1975. The bridge, designated County Trunk Highway Q for its first years, extended from US 41 to CTH-P, approximately. The bridge was also the last portion of the Tri-County Expressway completed for more than a decade, with the remainder of the expressway mired in the proposal stage. The exits were unsigned until 2019, when they were numbered to 441's mileage.
The bridge was given a state highway designation in the 1980s, with signs to this effect going up in 1985 or 1986. Movement to complete the full of freeway began in the late 1980s, and the first new stretch of freeway since 1975 was completed in November 1991, extending from CTH-P to US 10. The entire freeway length was completed in September 1993.

Future

Between 2012 and 2019, the Wisconsin Department of Transportation is working on expanding the route from east of I-41 to west of Calumet Street from four to six lanes along with upgrades of interchanges along the section. A large part of the work is completing the road's interchange with I-41 by installing missing ramps, adding auxiliary lanes to I-41 and upgrading the Kampo Memorial Bridge. Property was also acquired to allow the smoothing of two sharp curves from the Kampo Bridge to north of Midway Road, which allowed the speed limit for the entire length of WIS 441 to increase from.
As part of the project, the existing interchange with Oneida Street was converted to a diverging diamond interchange; it opened on November 3, 2018 after being closed since August.
