I-475 Rebuilding Michigan Project & Corridor Study

MDOT is rebuilding the I-475 corridor from Bristol Road to Carpenter Road, with work beginning in spring 2024.

MDOT has gathered public input at quarterly meetings on all aspects of vehicular, nonmotorized, and transit transportation needs in the project area. These projects are made possible through funding provided by Gov. Gretchen Whitmer's Rebuilding Michigan program.

The I-475 corridor improvements included a planning and environmental linkages (PEL) study. The PEL study is a collaborative process that considers environmental, community and economic goals in the transportation planning process.

Throughout the PEL process, MDOT has continued to gather input from the community through various forms of public engagement including meetings with the Local Advisory Council (LAC) and the Business Advisory Council (BAC), public meetings, one-on-one meetings, e-mails, and electronic applications. Linked below are presentation materials and videos used in the outreach process.

I-475 Completed Planning Environmental Linkages (PEL) Study

The planning environmental linkages (PEL) study for the I-475 corridor from Bristol Road north to Carpenter Road is now complete and can be viewed. This study was performed to promote a transparent and collaborative decision-making process for the I-475 planning process. The study was utilized to identify and evaluate alternatives that best meet the project’s purpose and meet the goals of the local community.

Three preliminary alternative concepts were identified and presented to the public. These alternatives were then screened with evaluation criteria to identify alternatives that best address the concerns of the community.

Implementing all concepts of the identified PEL Acceptable Alternative is estimated to more than double the cost of the original project, from $300 million to more than $700 million. Due to this cost differential, MDOT is evaluating what items of the PEL have the largest impacts on connectivity of the communities, applying for federal grant funding, planning a phased approach to the PEL Acceptable Alternative, and implementing what can be afforded. MDOT commits to move the I-475 project forward in line with the spirit of the PEL study and implement attributes that focus on connectivity of the local communities.

Throughout the upcoming project development phases, MDOT will continue robust public engagement to inform the public and accept feedback on proposed improvements.

MDOT will hold a virtual question-and-answer session related to the PEL study. Meeting details will be published in a separate press release.
