So this is what they're working on at 23 and 270

Drivers heading to Delaware County can access the trench after they exit the I-270/U.S. 23 Interchange. The trench begins ahead of Campus View Boulevard and exits just before Northwoods Boulevard South.

The trench is a little more than three-quarters of a mile long, has shoulders on sides, lights and drainage.

ODOT says the new configuration will ease congestion by allowing northbound thru-traffic to bypass the signals at Campus View and Flint Rd.

 

 

 

Interesting concept, hopefully it relieves some of the congestion that forms here which backs up onto the freeway and makes this one of the worst areas to drive through in rush hour. 

 

Edit: also modifying the interchange, not sure how I missed all of this but figured maybe others had too: http://www.dispatch.com/content/stories/public/2013/09/10/Project-to-smooth-out-270-and-23-set-to-start.html

That's all part of the plan.  They are getting rid of the double suicide merge and replacing it with a couple of flyovers so that if you want to go from eastbound 270 to southbound 23 you go into a different walled-off lane from if you want to go from eastbound 270 to northbound 23.  This ensure that the suicide merge is only ever one lane merging with one other lane, not two lanes merging with three.

Looks like no funding available until 2020 though.
