Diverging Diamond Interchange, Aerial View, Auburn Hills MI

An innovative, award winning road design to improve safety and capacity for metro Detroit commuters.

Bergmann served as the Prime Designer for the reconstruction of this critical intersection of high-volume highway over I-75 in metro Detroit. The project began after a routine inspection showed severe beam deterioration. The highway was closed and a plan to replace the bridge was quickly enacted. In order to improve safety and traffic capacity, the design included the first diverging diamond intersection in the state of Michigan.

In order to reduce the risks associated with poor soils near existing bridge abutments and to dramatically reduce the skew of the crossing, an alternative technical concept (ATC) was used to modify the bridge skew, saving significant project costs and construction time. The bridge realignment required significant changes to the roadway and ramp geometrics. A shorter crossing enabled the use of hybrid concrete bulb-tee girders resulting in less lead time and cost than alternative steel options. The new bridge also has extensive aesthetic enhancements including decorative lighting, an attractive steel fence and a large ornamental sign dedicated to the City of Auburn Hills.
