State Trunk Highway 441 (often called the Tri-County Expressway, Highway 441, STH 441, or WIS 441) is a state highway in the U.S. state of Wisconsin. Together with Interstate 41, the highway forms a beltway around the greater Appleton area, and is a freeway for the entire span of the route. It connects at both ends to its parent highway, I-41. It runs east–west and north–south in east central Wisconsin from near Neenah around Appleton to near Little Chute.

It routes through Winnebago, Outagamie and Calumet Counties. The Roland Kampo Memorial Bridge (known in the area as "The Polish Connection" due to the large percentage of Polish descent in the Menasha area) spans Little Lake Butte des Morts near the highway's southwest terminus.


441 at Newberry Street, Appleton.

The Roland Kampo Memorial Bridge was the first portion of this road completed; traffic began flowing on the bridge at 11 AM, November 30, 1975.[1] The bridge, designated County Highway Q for its first years, extended from U.S. Route 41 to County Highway P/Racine Road (approximately 1.3 miles). 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 bridge became known as the "Polish Connection" by locals over time.

The bridge was given a state highway designation (441) in the 1980s, with signs to this effect going up in 1985 or 1986.[1] Movement to complete the full 10.88 miles (17.51 km) of freeway began in the late 1980s, and the first new stretch of freeway since 1975 was completed in November 1991, extending from County Highway P to US 10/Oneida Street. The entire freeway length was completed in September 1993.[1]


US 10 follows the route from its southwest junction with I-41 in Neenah to Oneida Street just south of Appleton in Menasha where it turns off southeast. This junction is a partial cloverleaf interchange that does not include traffic movements. Due to safety concerns of being at-grade intersections four traffic movements were removed in 1997:

  • Southbound US 41 to westbound US 10.
  • Northbound US 41 to westbound US 10.
  • Eastbound US 10 to southbound US 41.
  • Eastbound US 10 to northbound US 41.

The eastbound US 10 to southbound US 41 and southbound US 41 to westbound US 10 were restored in 2001, leaving two missing connections.[2] The northeastern junction with I 41 is a trumpet interchange - with the loop ramp from I 41 westbound to WIS 441 southbound.

Improvement project[edit]

Work is currently[when?] underway on expanding the route from east of I-41 to west of Oneida St from four to six lanes along with the upgrading of interchanges along the section. A large part of the work is completing the road's interchange with I-41 by installing the missing ramps, adding auxiliary lanes to I-41 and upgrading the Kampo Memorial Bridge. Two "kinks" are also being removed as part of the plan, in order to increase the speed limit on 441 to 65 mph from its current 55 mph limit.[3][4]


The current work would allow WIS 441 to attain status as an auxiliary interstate (I-441), in concert with the completion of upgrading US 41 to Interstate 41 through the Lake Winnebago and Fox Cities communities.[3]
