I-43 (Silver Spring Dr.-WIS 60) North-South Corridor - Environmental documents

The environmental study process is just beginning. View the public involvement page for the latest opportunities to provide input.

The Federal Highway Administration, in cooperation with WisDOT, will prepare an Environmental Impact Statement (EIS) for proposed improvements in the I-43 corridor and adjacent interchanges in Milwaukee and Ozaukee counties. The purpose of the study is to address emerging pavement and structural needs, safety issues and design deficiencies while identifying methods to accommodate existing and projected future traffic volumes.

This may result in the full reconstruction and redesign of the I-43 corridor as well a potential new interchange at Highland Road. The EIS will evaluate the I-43 freeway corridor from I-43 at Silver Spring Drive on the south to I-43 at WIS 60 on the north, approximately 14 miles in length.

The EIS will also evaluate the service interchanges and adjacent arterial roads in Milwaukee and Ozaukee counties, including the following service interchanges:

Silver Spring Drive
Good Hope Road
WIS 100/Brown Deer Road
Partial interchange northbound to Port Washington Road
Southbound from County Line Road
WIS 167/Mequon Road
County C
WIS 60
