I-43 North-South Corridor - Environmental information

Final Environmental Impact Statement and Record of Decision

November 25, 2014

Draft Environmental Impact Statement (DEIS)

March 28, 2014


The Federal Highway Administration, in cooperation with WisDOT, has prepared an Environmental Impact Statement (EIS) for proposed improvements in the I-43 corridor in Milwaukee and Ozaukee counties. The EIS presents the need for proposed improvements, the alternatives considered to address the identified needs, and the impacts resulting from the reasonable range of alternatives being considered. A discussion of potential mitigation concepts is also included, as well as a summary of the coordination conducted with the public, interested stakeholders, and review agencies.

The EIS also evaluates adjacent arterial roads in Milwaukee and Ozaukee counties, including Port Washington Road and Jean Nicolet Road, and the following interchanges:

  • Silver Spring Drive
  • Good Hope Road
  • Brown Deer Road/WIS 100
  • County Line Road
  • Mequon Road/WIS 167
  • County C/ Pioneer Road
  • WIS 60

Understand WisDOT's structured approach to analyzing impacts of the proposed transportation project and its alternatives by viewing the Impact Analysis Methodology.

The national and Wisconsin environmental policy acts require environmental documentation 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 is prepared in accordance with FHWA guidelines.

Comments

WisDOT conducted a Public Hearing on April 30 and May 1 to solicit comments on the DEIS and the Preferred Alternatives presented in the document. View the Public involvement page for more information.

Since no substantive new information related to environmental impacts or safety was received during the public comment period, FHWA and WisDOT issued a combined Final EIS (FEIS) and Record of Decision (ROD). Both the DEIS and FEIS are full-disclosure documents, which provide a full description of the proposed project, the existing environment, and an analysis of the anticipated beneficial and/or adverse environmental effects.
