M-DOT Proposes Diverging Diamond Interchange for I-75 at 12 Mile Road

[Scottathew]

M-DOT is proposing a Diverging Diamond Interchange for I-75 at 12 Mile Road. This is the same kind of interchange that is currently at University Drive, Big Beaver Road, and 14 Mile Road. Keep in mind that the ones at Big Beaver and 14 Mile are a little messy and not in their final form yet.

DDI's eliminate many conflict points and opposing-traffic turns. This makes these intersections a lot safer than other designs.


Huge improvements over the previous design include the elimination of the tight loops to enter I-75. This means that traffic will no longer be entering I-75 at 12 Mile going 25 miles per hour with this new design. Much better for large trucks that have difficulty accelerating quickly.


Some folks might not like the change but I highly encourage folks to get familiar with them. These are a lot safer and as a father, husband, brother, and son I appreciate new road designs that keep my family safe.
