Why is the I-75 median so wide south of Dayton?

Why is the I-75 median so wide south of Dayton? Is there an engineering reason for this, such as needing the extra median for water to collect? See:

Interstate 75 was designed for express/local lanes in several areas (mileposts approximate):

• Milepost 14 in Sharonville to Milepost 24 in Liberty Township
• Milepost 38 in Franklin to Milepost 48 in West Carrollton

Similarly, Interstate 271 has express/local lanes from Interstate 480 near Macedonia to Interstate 90 in Wickliffe. Interstate 90 was designed for express/local lanes, never built, from Interstate 271 east Milepost 200 at Painesville.

Of course, I've driven through there, but I've never really viewed things from that angle. I didn't realize it was so wide. I thought they were showing a picture of maybe Atlanta at first.

Hopefully, future reconstruction projects will be implemented to eliminate the unnecessary space in the medians of those portions of the freeways.

These huge medians are everywhere in Michigan with uncut trees, very nice because the trees block highbeams.

I agree that it is reserved space for an undefined future upgrade to the highway.

Wasn't there also talk of a passenger rail corridor in the median at some point?
