I-94 East-West Corridor - Environmental information

Environmental Impact Statement (EIS)

Environmental Impact Statement (EIS) Draft and Final EIS documents will be prepared. The EIS will document the need for proposed improvements, the alternatives considered to address the identified needs, and then present and discuss the impacts resulting from the reasonable range of alternatives being considered. A discussion of potential mitigation concepts will also be included, as will a summary of the coordination conducted with the public, interested stakeholders, and review agencies.

Environmental documentation is required by national and Wisconsin environmental policy acts for projects with potentially significant social, economic, natural resource and other impacts. The Federal Highway Administration (FHWA) is the lead agency for the EIS, which will be prepared in accordance with FHWA guidelines.

The EIS and study process is scheduled for completion December 2014.

Section 2 of the Draft EIS documents the alternatives that WisDOT and the Federal Highway considered to address the needs identified in the Purpose and Need statement. The latest version of Section 2 was sent to all participating and cooperating agencies in June 2014.


The Purpose and Need statement for the Draft Environmental Impact Statement was updated based on comments received from Participating and Coordinating Agencies following their review of the Purpose and Need in November 2012. Edits made to the text as a result of the Participating and Cooperating Agency comments are highlighted in gray.
