There are five concepts being considered, one of which is a full freeway with frontage roads along the Columbus to Waldo segment. I made my comments known that ODOT should consider a full build-out as a freeway, and that it could be staged over the years with right-of-way acquisitions. Essentially, phasing it in.
The path of least resistance is to leave US 23 alone south of Delaware lake (except for modest enhancements), build a bypass and then use US 36. It will get the job done for now. It may not be ideal looking out 40 years, but for the time being, it will get the job done. That was the reason for building US 36 the way it was built, wasn't it?
The problem with frontage roads and fixing US 23 is that even though they put all that effort into fixing US 23 the last time, there are still backups around there, especially when going I-270 East from US 23. The backups have now moved to the I-71 exit going to Polaris. That I-71 North Lane is backed up and it's hard to go eastbound on I-270 because you basically have to weave through two or three lanes, come to a standstill and then try to merge onto I-270.
US 23, 315 and I-71 are simply too close to each other to ever get that working right, unless you build several dozen flyover lanes. I'm exaggerating, of course, but you get the idea.
I'm also fearful that they will do to US 23 what they did to US 19 and Pinellas County. That will just ruin all the commercial land with overpasses blocking everything.
