Diverging Diamond Interchange (DDI) Opens at I-75 and University Drive
Michigan’s first diverging diamond interchange (DDI) is officially open in Auburn Hills
Part of a $25 million reconstruction of the interchange of I-75 and University Drive, the DDI improves traffic flow for thousands of drivers. This innovative transportation solution effectively handles areas of heavy left turn traffic and allows pedestrians to safely cross the bridge.
This project also includes a multi-use path, new signs, new traffic signals, decorative lighting and landscaping.
It is both the only interchange of its kind and features the only community-branded bridge in the state.
This project was a collaboration with Michigan’s Department of Transportation (MDOT) and the City of Auburn Hills. OHM Advisors’ role included a conceptual engineering study, preliminary design, geometrics and landscape architecture.
