I-75 Mega Project to Include Diverging Diamond Interchanges at 14 Mile, Big Beaver

[Scottathew]

At the end of the 2020 construction season M-DOT will complete two new Diverging Diamond Interchanges [[DDIs). These interchanges are much like the interchange at I-75 and University, with the exception that I-75 is under the bridge at University, and these new DDI's will have I-75 going on the bridge. No more A's and B's at exit 65 and 69, they'll only have one exit with no letters!

DDI's are cited as being much safer and providing better traffic flow because they eliminate the number of turns and completely eliminate left-hand turns.

Here are the drawings for it:
