US 10/WIS 441 expansion study - alternatives

US 10/WIS 441 | US 41

The long-range improvement concepts include:

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.

As part of the original expansion study, preliminary alternatives were evaluated at each interchange within the study corridor and preferred alternatives were selected. These preferred alternatives ranged from minimal to substantial improvements.

The renewed study is evaluating new preferred alternatives at the County P (Racine Street) and the County AP (Midway Road) interchanges. Preferred alternatives at the other interchanges are unchanged from the original expansion study.

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, was selected as the preferred alternative. This preferred alternative is not affected by the renewed expansion study.

Southwest loop 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.

County P (Racine Street) interchange

Two alternatives were considered in the original study, and a trumpet configuration similar to the current layout was selected as the preferred alternative.

In our renewed study, the location of the interchange is shifted to the north due to the flattening of the horizontal curve on US 10/WIS 441 through this area. A new preferred interchange alternative has been selected to provide smooth traffic flow through the interchange and minimize real estate impacts.

Preferred County P alternative (368 KB)

The new alternative includes:

Constructing new US 10/WIS 441 bridges over Racine Street on and off-ramps and realigning US 10/WIS 441 to flatten horizontal curvature.
Constructing a more traditional “diamond” style layout for the westbound on and off-ramps and including a roundabout at the westbound ramp terminal intersection.
Constructing free-flow eastbound on and off-ramps similar to the existing layout.
Investigating a roundabout at the intersection of Racine Street with the interchange ramps.
Restricting access from 12th Street to Racine Street to right-in/right-out only.

County AP (Midway Road) interchange

Three alternatives were considered in the original study, and the ‘Modify Existing Diamond’ alternative was selected as the preferred alternative.

In our renewed study, the location of the interchange is shifted to the east due to the flattening of the horizontal curve on US 10/WIS 441 through this area. A new preferred interchange alternative has been selected to provide smooth traffic flow through the interchange and minimize real estate impacts.

Preferred County AP alternative (358 KB)

The new alternative includes:

Constructing new US 10/WIS 441 bridges over Midway Road and realigning US 10/WIS 441 to flatten horizontal curvature.
Investigating a roundabout at the intersection of County AP with westbound on and off-ramps.
Reconstructing a portion 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

The interchange ramp alignments will not change from the existing configuration. However, the renewed study will investigate roundabouts at the ramp terminal intersections and at the intersections of WIS 47 with Valley Road and Midway Road.

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.
Adding turn lanes at ramp and crossroad intersections.
Lengthening the on and off-ramps.
Transitioning from six-lane roadway to existing four-lane roadway east of the interchange.

Little Lake Butte des Morts crossing

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.
Re-decking 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.

County BB (Prospect Avenue) interchange

No improvements are planned.
