Building safer interchanges
 
Strategically improving critical interchanges along US 41 will lead to increased safety levels and smoother flowing traffic along the corridor. The US 41 Project includes improvements to 16 interchanges, of which 13 will be completely rebuilt. We’ll be using a combination of improvement tactics including, but not limited to:
  • Lengthening of on and off ramps to prepare for future metering
  • Widening of lanes
  • Adding roundabouts
Affected US 41 interchanges in Winnebago County (WIS 26 to Breezewood Lane)

At the WIS 26 interchange in Winnebago County WisDOT will:
  • Construct crash investigation sites (widened pull out areas) at the WIS 26 northbound and southbound exit ramps, and at the WIS 44 southbound exit ramp. These will help minimize traffic backups and delay by allowing vehicles involved in minor crashes on US 41 to move off the freeway.

Proposed 9th Avenue interchange 9th Avenue interchange (rebuild)
At the 9th Avenue interchange in Winnebago County WisDOT will:
  • Reconstruct the interchange to a tight diamond configuration with multi-lane roundabout on 9th Avenue and at ramp ends.
  • Reconstruct the 9th Avenue bridge over US 41.
  • Slightly relocate the east frontage road (Koeller Street) to accommodate the new northbound on-ramp.
  • Lengthen on-ramps for future ramp metering.
  • Reconstruct the CTH E bridge (Witzel Avenue) over US 41, including bicycle and pedestrian accommodations.
 
At the WIS 21 interchange in Winnebago County WisDOT will:
  • Reconstruct the existing interchange using a tight diamond configuration and roundabouts on WIS 21 and ramp ends.

  • Lengthen on-ramps for future ramp metering.
  • Shift US 41 west to avoid electric substation.
  • Construct a new bridge over US 41 to connect Lake Butte des Morts Drive on the west to Algoma Boulevard on the east. The Wiouwash Trail will use this bridge to go over US 41.

WIS 29 interchange rendering in Brown County
WIS 29 in Brown County will be reconstructed between CTH J and Taylor Street concurrently with the US 41 construction. The US 41/WIS 29 interchange will be improved to a multi-level systems interchange with free-flow directional ramps connecting US 41 and WIS 29. WIS 29 and US 41 are both backbone routes and have the highest degree of importance within the state transportation system. Improving the connectivity of this interchange is essential to the continued safe, efficient transportation between major cities of the state.
At the planned US 41/WIS 29 interchange WisDOT will:
  • Construct a collector-distributor (C-D) roadway for northbound and southbound US 41 traffic between Mason Street and WIS 29. The C-D roadway is a separate roadway paralleling the mainline US 41. The function of the C-D roadway is to provide improved, safe and efficient traffic flow and weaving (lane shifts occurring simultaneously by multiple motorists) between the closely-spaced Mason Street and WIS 29 interchanges.
  • Embed a Shawano Avenue/US 41 service interchange within the systems interchange. Local access to Shawano Avenue from US 41 will be the same, only it will now be accomplished via the C-D roadway.
  • Construct multi-lane roundabouts at the ramp termini of the US 41/Shawano Avenue service ramps.
  • Construct a series of multi-lane roundabouts along the south frontage road, Packerland Drive and Shawano Avenue. A total of eight roundabouts are planned, including at the Shawano Avenue/Taylor Street intersection and the US 41/Shawano Avenue ramps.
The WIS 29 work will:
  • Provide a grade separation of the CTHJ/WIS 29 intersection. Access will be removed here.
  • Provide a south frontage road between CTH J and Packerland Drive.
  • Install an interchange at Packerland Drive.
  • Reconstruct Taylor Street between Dousman Street and north of Badger Street.
  • Removal of Dousman Street from US 41 SB ramp to Taylor Street.
  • Construct a shared-use path along the north side of Shawano Avenue from Pamperin Park to Taylor Street.
WIS 29 construction timelines:
  • Shawano Avenue/Taylor Street roundabout—begin construction fall 2011
  • WIS 29 interchange—Still under evaluation; tentative timeline 2011 to 2015
 
I-43 interchange US 41 and I-43 interchange
WisDOT, in cooperation with the Federal Highway Administration (FHWA) is preparing an Environmental Impact Statement (EIS) for improvements on US 41 from Memorial Drive to County M (Lineville Road). An EIS is the decision document for major highway projects developed under the National Environmental Policy Act. It includes the purpose and need for the project, alternatives and environmental consequences. The Final EIS, prepared after a public hearing, identifies the recommended alternative and reasons for its selection.

Draft EIS section 1 (purpose and need) and section 2 (alternatives) have been completed and made available to local officials, state and federal review agencies for review and comment. An opportunity for public review is being provided by posting these Draft EIS sections on the US 41 Project website (see links). WisDOT encourages interested persons to review these documents and provide any comments to the WisDOT Project Manager listed below. Comments or questions should be provided by October 1, 2010. The entire Draft EIS will be posted on the project website at a later date, prior to the public hearing.

CTH M (Lineville Road) interchange in Brown County
The interchange at CTH M in Brown County will be reconstructed within the existing ramp configuration to address operational deficiencies at the ramp terminals. The southbound entrance ramp will be rebuilt, and the northbound exit ramp will be reconstructed as a two-lane ramp. In addition, US 41 will be expanded to six lanes, plus auxiliary lanes, from CTH M to the south.
 
The CTH M work will include:
  • Constructing roundabouts at the northbound and southbound ramp terminals, and at the intersection of County M with East Deerfield Avenue and West Deerfield Avenue.
  • Constructing an additional lane for westbound traffic on County M.
  • Constructing a free-flow right-turn lane for eastbound traffic at the southbound ramp terminal.
  • Raising the County M bridge over US 41 to provide greater vertical clearance.
