The I-94 East-West Freeway is one of the busiest routes in the
state and is identified as a Corridors 2030 Backbone route. The
corridor provides access to manufacturers, commuters and tourists
within the Milwaukee metropolitan area and between Milwaukee and other
areas including Madison, Chicago and Green Bay.
Because of the outdated design, this part of the freeway system has
over 300 crashes per year, which translates into a crash rate
significantly higher than the statewide average for similar facilities
(urban freeways). About 89% of the corridor contains crash
problems that are significantly greater than the statewide average.
Existing/future traffic volumes
This section of I-94 carries high traffic volumes, which currently
vary between 138,000 and 156,000 AADT (Average Annual Daily Traffic).
These traffic volumes are expected to grow to a range from 171,000 to
181,000 by 2030; traffic increases range from 15% to 25% or more over
WisDOT is conducting this study at the direction of the Transportation
Projects Commission, or TPC, as a candidate “major” project per
Wisconsin statutes. The TPC
and Legislature have directed WisDOT to determine what, if any,
reasonable alternatives can be developed to address the poor physical,
operational, and safety characteristics of the existing highway
through the study area.
WisDOT will investigate the existing corridor to assess access
patterns, traffic volumes and operations, and other elements to help
quantify what improvements may be warranted.
As part of the alternatives development process, any resulting impacts
to adjacent homes, businesses and other lands will be quantified and
presented in an Environmental Impact Statement to aid WisDOT, the
Federal Highway Administration, review agencies, and interested
stakeholders in the determination of the reasonableness of potential
Major study outcomes include:
Data collection within the corridor
Determination of access and infrastructure needs.
Traffic capacity analysis and forecasts.
Review of existing safety performance, and
the efficiency of current freeway operations.
Development of design alternatives, which
will include a “no-build” (maintenance) option.
Evaluating these alternatives and their
impacts to homes, businesses, industries, institutions, public
facilities, organizations, natural resources and the traveling
