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.

    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 Big Beaver interchange is anticipated to open mid-April, while 14 Mile Road Interchange is anticipated to open in Spring of 2021.

    Update February 9, 2021 - The DDI at Big Beaver Road is scheduled to open by mid-April. Several activities need to take place including installing new signals, application of permanent and special pavement markings, and constructing new curbs. Crews are awaiting suitable weather to complete these necessary steps.  Thank you for your continued patience.  


    DDI’s are a safer option for both motorists and pedestrians.
