Adding mainline capacity on US 10/WIS 441 including an
additional bridge over Little Lake Butte des Morts
Upgrading existing interchanges
Adding auxiliary lanes where needed
Note - The following sections summarize
concepts that were developed during previous planning studies. Some
design concepts may be updated during the ongoing preliminary
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.
Renewed study evaluated new preferred alternatives at the County P (Racine
St.) and the County AP (Midway Rd.) interchanges. Preferred alternatives at the other interchanges are unchanged from the original expansion study.

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.
Retaining loop ramp in southwest quadrant for southbound US 41
to eastbound US 10
Constructing flyover ramp over US 41 for eastbound US 10 to
northbound US 41
Constructing flyover ramp over US 41 and US 10/WIS 441 for
westbound US 10 to southbound US 41
Constructing flyover ramp over US 41 for northbound US 41 to
westbound US 10
Constructing direct connection ramps for other movements
County P (Racine St.) 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 was 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.
Constructing new US 10/WIS 441 bridges over Racine St. on and
off-ramps and realigning US 10/WIS 441 to flatten horizontal
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
Proposing a roundabout at the intersection of Racine St.
with the interchange ramps
Restricting access from 12th St. to Racine St. to
County AP (Midway Rd.) interchange
Three alternatives were considered in the original study, and ‘Modify Existing Diamond’ alternative was selected as
the preferred alternative.
In the renewed study, location of the interchange was shifted east due to the flattening of the horizontal curve on US 10/WIS 441 through this area. A new preferred interchange alternative
was selected to provide smooth traffic flow through the interchange and minimize real estate impacts.
Constructing new US 10/WIS 441 bridges over Midway Rd. and
realigning US 10/WIS 441 to flatten horizontal curvature
Proposing roundabouts at the intersections of County AP
with eastbound and westbound entrance and exit ramps
Reconstructing portion of County AP in the interchange area
Lengthening on and off-ramps
WIS 47 (Appleton Rd.) interchange
Interchange ramp alignments are not expected to change from existing configuration. However,
WisDOT will investigate the use of roundabouts at ramp terminal intersections and at intersections of WIS 47 with Valley
Rd. and Midway Rd..
