WIS 106 Project History

• WIS 106 Roadway:
• 1954: Roadway reconstruction
• 1954 -1996: Mill & overlays; most recent 1996
• 2001: Pulverize & overlay
• Structures:
• B-28-0107: concrete flat slab bridge, constructed 2001
• B-28-0108: two span concrete slab bridge, constructed in

2001

• C-28-0011: 12-ft x 8-ft box culvert, widened in 1954

B-28-0107 B-28-0108 C-28-0011

WIS 106 Project History

• Current Roadway Issues:
• Existing pavement is

deteriorated with cracking and rutting

• Structure C-28-0011 does

not have guardrail to protect the blunt ends of concrete parapets

WIS 106 Project History

• Safety Screening Analysis conducted by WisDOT
• No crash patterns attributed to the existing roadway geometry
• Crashes are attributed to vehicle failure, driver impairment, and

weather-related crashes

• There were some run off the road crashes at the east end along the

river

WIS 106 Design Considerations

• Design Alternatives Considered
• Do Nothing – Roadway will continue to deteriorate
• Full Reconstruction – Complete replacement of the roadway structure
• Extensive right of way impacts
• Right of way acquisition needed for ditch widening, culvert extensions
• Extensive environmental impacts
• Wetland impacts, tree clearing
• High project cost
• Excessive costs given that the existing roadway base materials and lower

layers of pavement can still be used.

• Mill and Overlay (Preferred Alternative) – Remove and replace top

pavement layers

• Minimal impacts
• Cost Effective method that addresses the roadway issues efficiently

WIS 106 Proposed Improvements

• Pavement Improvements – Mill & Overlay (Preferred Alternative)
• Mill 2 ½ to 3 ½ inches of the top of the existing asphalt pavement.

Then add 2 ½ to 3 ½ inches of new asphaltic pavement.

• Existing shoulder widths (4 to 10 feet) to be maintained
• Increased paved shoulder widths in some areas (add 1 to 2 feet)
• Some added base aggregate to reshape gravel shoulders

Existing Proposed

WIS 106 Proposed Improvements

• Safety Improvements – Mill & Overlay (Preferred Alternative)
• Guardrail improvements
• Added guardrail at east end of project along the river
• Added guardrail at structure C-28-0011
• Evaluating possible improvements to existing guardrail at B-28-0107 and B-

28-0108

WIS 106 Proposed Improvements

• Safety Improvements– Mill & Overlay (Preferred Alternative)
• Centerline Rumble Strips
• Reduces head-on and run-off-road to left crashes

WIS 106 Proposed Improvements

• Structures Improvements
• Concrete Deck Overlays were evaluated

at bridges B-28-0107 and B-28-0108

• Infrared scans revealed that the decks are

in good shape – overlays are not needed at this time

• Improvements to box culvert C-28-0011
• Replace displaced wingwalls
• Cross Culvert Replacement
• Culvert inspections performed by Dane

County and Jefferson County.

• One culvert in need of replacement (west
• f Kruetz Road intersection)

Proposed Schedule & Traffic Impacts

• The project is expected to be constructed

during the summer of 2022

• It is anticipated that the project will be staged
• One lane constructed at a time
• Flagging will be utilized to maintain one lane of

traffic.
