US 10/WIS 441 expansion alternatives

US 10/WIS 441 | US 41

The long-range improvement concepts on US 10/WIS 441 and US 41 include the following:

• Adding mainline capacity on US 10/WIS 441 including an additional bridge over Little Lake Butte des Morts.
• Upgrading the existing interchanges.
• Adding auxiliary lanes where needed.

Preliminary alternatives were evaluated at each interchange within the study corridor and range from minimal to substantial improvements. Preferred alternatives have now been selected at all interchange locations and are summarized below. The alternatives include adding another driving lane in each direction on US 10/WIS 441 and outside auxiliary lanes between interchanges where needed.

US 10/WIS 441 interchanges

County CB Interchange

No improvements planned.

US 41 Interchange

Three alternatives were originally considered at the US 10/US 41/WIS 441 system interchange. The "southwest loop" alternative (described below) has been selected as the preferred alternative.

The southwest loop alternative includes:

• Retaining the loop ramp in southwest quadrant for southbound US 41 to eastbound US 10.
• Constructing a flyover ramp over US 41 for eastbound US 10 to northbound US 41.
• Constructing a flyover ramp over US 41 and US 10/WIS 441 for westbound US 10 to southbound US 41.
• Constructing a flyover ramp over US 41 for northbound US 41 to westbound US 10.
• Constructing direct connection ramps for other movements.
• Constructing additional lanes within the interchange at the southbound US 41 to eastbound US 10 ramp and the westbound US 10 to southbound US 41 ramp.

County P (Racine Street) Interchange

Two alternatives were considered. Based on collaborative discussions amongst the study team, review of public comment, and further refinement at a Value Engineering study in August 2003, the "preferred trumpet" alternative was selected as the preferred alternative. 

The preferred trumpet alternative basically maintains the existing configuration with minor changes.

The preferred trumpet alternative includes:

• Constructing a new bridge for eastbound US 10/WIS 441 traffic over Tayco Street.
• Widening and redecking the existing bridge for westbound US 10/WIS 441 traffic over Tayco Street.
• Constructing new US 10/WIS 441 bridges over Racine Street on and off-ramps.
• Maintaining a free-flow design and similar alignments for directional ramps within the interchange.
• Restricting access from 12th Street to Racine Street to right-in/right-out only.

County AP (Midway Road) Interchange

Three alternatives were originally considered at the County AP (Midway Road) interchange. The 'modify existing diamond' alternative has been selected as the preferred alternative.

The modify existing diamond alternative includes:

• Constructing new US 10/WIS 441 bridges over Midway Road and partially realigning US 10/WIS 441 to improve the curvature across the bridges.
• Reconstructing portions of County AP in the interchange area.
• Adding turn lanes at ramp and crossroad intersections.
• Lengthening the on and off-ramps.

WIS 47 (Appleton Road) Interchange

Improvements include:

• Widening US 10/WIS 441 bridges over WIS 47 (Appleton Road) to accommodate six lanes.
• Adding turn lanes at ramp and crossroad intersections.
• Lengthening the on and off-ramps.

Oneida Street Interchange

Improvements include:

• Widening the US 10/WIS 441 bridges over Oneida Street to accommodate six lanes.
• Reconstructing a portion of Oneida Street in the interchange area.
• Adding turn lanes at ramp and crossroad intersections.
• Lengthening the on and off-ramps.
• Constructing a transition from a six-lane roadway to the existing four-lane roadway east of the interchange.

Little Lake Butte des Morts crossing

Cross section of existing crossing and preferred alternative (158 KB)

Improvements include:

• Adding a new parallel bridge south of the existing bridge. This new bridge will handle eastbound traffic and will have three through lanes and one auxiliary lane.
• Redecking the existing bridge. The existing bridge will handle westbound traffic and will have three through lanes and one auxiliary lane.

US 41 interchanges

County II (Winchester Road) Interchange

Improvements include:

• Adding turn lanes at ramp and crossroad intersections.
• Adding an auxiliary lane along US 41 northbound from the County II on-ramp to US 10/WIS 441.

County BB (Prospect Avenue) Interchange

No improvements are planned.
