I-70/71 Columbus Crossroads

(1/31) > >>

vtk:
Here's a thread that should hopefully be around for a while.  This project aims to improve I-70 from Central Ave to Miller Ave, I-71 from Greenlawn Ave to I-670, and I-670 EB from Cleveland Ave to Joyce Ave, most notably including the I-70/71 overlap on the South Innerbelt.

Columbus Dispatch article about start of construction and a nickname: http://www.dispatch.com/content/stories/local/2011/09/15/road-project-name-now-up-to-voters.html (I actually don't quite like any of the finalist nicknames...)

I'll try to post more information as I catch it.  When I have time, I'll also try to come up with some roadgeeky illustrations derived from the various documents I've downloaded.

So WB I-670 is getting shifted south to follow the EB lanes?

I don't know about the proposed design; it just seems that it would be better to try to relocate EB I-670 northward to follow the WB lanes and try and then either try for a stack interchange, or downgrade the current EB lanes to provide for EB to SB and NB to WB movements.

There's a couple a things askew with that image. There is no connection between I-71 NB to I-670 WB. On top of that, the "proposed" WB 670 just runs over the existing 71 NB to 670 WB connector (that somehow doesn't connect to 71 NB). The ramps from I-71 SB (and I-670 WB) to Leonard Ave/Cleveland Ave (Ft. Hayes) have disapeared too

Here is my question:  What is so bad about the current I-71/I-670 interchanges that they have to pour a quarter of a billion dollars to re-build it? 


I can name at least a half-dozen other major freeway interchanges in the state, plus about two dozen non-interchange improvement projects on freeways that are far more deserving (and older) than this one!


But I guess the folks at ODOT really want to spruce up the gateway to the misspending of Ohio tax dollars.
