I-80/US 65/US 6 interchange to be redone

[Revive 755]

Would be nice to have a map showing the new configuration, much less a list of alternatives considered, but I'm guessing the interchange will be converted to a standard diamond.

And whatever happened to the left exit from WB I-80 to SB I-235?

And whatever happened to the left exit from WB I-80 to SB I-235?

It's still there.  The article writer either ignored Interstate-to-Interstate left exits (since the northbound I-35 "through movement" is also technically a left exit), or forgot about them.

I E-mailed the project engineer and got a PDF of the preliminary layout.  IaDOT is proposing a 5-ramp par-clo, with the loop being from EB 6 to WB 80, which would also make SB 65 to WB 80 a direct ramp.

As of 2/17/2011, the old ramp from EB I-80 to NB US 65 is closed off, but the bridge still remains.

The new signage for US 65 on EB I-80 could have been done a little better; the exit only arrow points to the shoulder.

They just rearranged the existing signs as a stopgap move until reconstruction is finished. (A "before" photo of what the signs on eastbound I-80 looked like last summer can be found here.)
