Project Introduction

Rendering of a divergent diamond interchange

The diverging diamond interchange (DDI) design will modernize the Big Beaver and 14 Mile Road interchanges and improve both vehicle and pedestrian safety.

Accelerated project construction will get Michigan moving smarter, safer, sooner.

Sustainable transportation across the state is vital to Michigan’s quality of life and economy.

Connecting families, business and regions across the state.

Intelligent Transportation System (ITS) technology will monitor real-time traffic conditions along the I-75 corridor.

A new tunnel will collect stormwater drainage from the corridor to support safe travel.

    Announcements

    Attention residents of the City of Troy and motorists who use the Big Beaver or 14 Mile Road Interchanges:

    As part of the I-75 Modernization Project, the interchanges at Big Beaver and 14 Mile Roads are being reconstructed into Diverging Diamond Interchanges (DDI’s). The DDI’s are expected to open in late November 2020 and are a safer option for both motorists and pedestrians. To learn more about DDI’s including how to navigate them please visit our Project Highlights - DDI Edition page under “Travel I-75”.   Stay up-to-date with information about the project by signing for email blasts or following our social media channels.
