I-794 Lake Interchange Study

Exploring Possibilities Together

Let’s work together to deliver safe and efficient solutions that will enhance community connectivity, create land use opportunities and keep downtown and the region connected.

Latest News

The Federal Highway Administration (FHWA), in coordination with the Wisconsin Department of Transportation (WisDOT), is issuing a Notice of Intent (NOI) to solicit comment and advise the public, agencies and stakeholders that an Environmental Impact Statement (EIS) will be prepared to evaluate transportation solutions for the Lake Interchange on I-794. The EIS will be prepared in accordance with the requirements of the National Environmental Policy Act (NEPA). The NOI and the Supporting Information Documents are available at the Federal Register and are located on our library page. Comments on this NOI and the Supporting Information Documents must be received on or before January 5, 2026.

Alternative Groups

All alternative groups will be further evaluated in the environmental impact statement to arrive at a selected alternative. Explore each alternative in detail.

Study Overview

The Lake Interchange Study is evaluating alternatives for the I-794 freeway corridor. The study is focused on aging infrastructure along a section of I-794 known as the Lake Interchange. The study corridor extends beyond the Lake Interchange, generally from the Marquette Interchange to the Hoan Bridge, due to the interconnectedness of the freeway and its ramps in this area. The study is exploring ideas to improve the freeway corridor while also considering how the project could improve surface street connectivity and safety so all modes of transportation can thrive in this urban environment. The study is not considering changes to the main span of the Hoan Bridge or core design of the Marquette Interchange.
