The project extends from the Illinois state line to the US 12/18
interchange near Madison, in Dane and Rock counties.
Will there be any property acquisition for this expansion project?
In many areas, the Wisconsin Department of Transportation (WisDOT)
will need to acquire additional property to accommodate expansion. Not everyone will be affected. The project team will work
with property owners during PIMs and throughout the acquisition
Are the traffic problems along I-39/90 that serious?
Yes. By the year 2030, with no corrective action, all sections of
I-39/90 are expected to operate at unacceptable levels of service,
resulting in poor traffic flow and increased safety problems.
Yes. An Environmental Assessment (EA) was conducted
from 2001 to 2006 to examine the Interstateís future needs and showed
that the demands placed on the corridor in the coming years will
stress the current facility beyond its capabilities.
The project underwent a statutorily-set evaluation that considers a
projectís potential to enhance economic development, relieve traffic
congestion, improve safety and achieve community objectives while
minimizing environmental impacts.
Why is I-39/90 in Janesville being expanded to
Due to projected traffic increases in the Janesville area (90,000
vehicles per day), the Interstate will be expanded to eight lanes for
6.5 miles from WIS 11 (Avalon Rd.) north to WIS 26.
