I-75 & University Interchange

[mikeg19]

With the talk of the widening of I-75 and a new diverging diamond interchange in University, it made me wonder what the original design of this part of the freeway was, particularly the Chrysler interchange to exit/enter I-75. When you are exiting northbound onto University, there are large swaths of cement that look like they were used at some point for merging traffic. This is particularly noticable as you're exiting the freeway and you can see the MDOT electronic traffic sign. Another area where it appears as if the designs have changed is the overpass for Featherstone. There is more than enough room for an additional 2 lanes of traffic going under the bridge northbound, with more pavement extending out toward the M-59 entrance onto I-75 northbound.

Anyone know anything about this? Any info on what this was supposed to look like or did look like? Aerial maps don't show anything back from the 60's.
