The North Central Outerbelt Study Proposed Interchange Maps
(For interchanges along I-270 with Oh 315, US 23, & I-71)

This page will be up only temporarily, till the Ohio Department of Transportation puts up its proposals for the North Outerbelt up on its website for all (who were unable to attend their last meet & greet on this project back on June 9, 2004). This is not secret material, for the following all comes from handouts given by ODOT. THIS PAGE IS NOT AFFILIATED WITH ODOT, THE CITY OF COLUMBUS, NOR THE MID OHIO REGIONAL PLANNING COMMISSION!!!

I-270 @ I-71 (North)

Of note here is ODOT's proposal to buy land from Anheiser Busch (on the SW corner of this interchange) so as to take the ramp from I-270 EB to I-71 further out, thus allowing the room for a ramp to I-71 NB without incoviancing many people (and animals, with Sharon Woods MetroPark on the NE corner there) and taking out one of the two nasty cloverleaf circles between I-71 and I-270.
I do not know the purpose of the proposed flyover ramp from I-71 SB to I-270 EB (along with what appears to be a slip ramp for EB I-270 to the Cleveland Ave/Oh 710 interchange). There was no mention of it by any of the staffers (from ODOT, MORPC, and City of Columbus) at the meeting. An 2nd alternative? Future expansion if needed?

I-270 @ OH 315

This proposal, in my (amateur traffic engineering) opinion seems to be the strangest of the group. Of note here here are a proposed flyover ramp from Oh 315 NB to I-270 WB, and what I would describe as an "paperclip" designed ramp from Oh 315 SB to I-270 EB. Thankfully, Oh 315, coming south from Delaware, is not the prefered trucking route, but with plenty of cars still using it, this curved exit could end up introducing new problems to this interchange.
Since you might be wondering by now why ODOT has put that "strange" ramp in for 315 SB to 270 EB, that is because of ODOT's proposal to channel traffic to both directions of Oh 315 and US 23 much further ahead than is the case now, while using as much of the current infrastucture as possible.

I-270 @ US 23

If the map here looks blurry and hard to distinguish the lane proposals, that is my fault. I failed to pick up a large scale map of this interchange and instead had to blow up a smaller map to compensate.

For the I-270-US 23, ODOT prefers to reuse the current interchange location and take out half of the existing cloverleaf. To compensate, ODOT is proposing a modified Single Point Urban Interchange (a Double Point in this case?) with two traffic lights coordinating traffic coming onto US 23 from I-270. There would be a bunch of slip ramps to channel WB traffic heading for I-270 WB and Oh 315, both from I-270 and US 23.

US 23 - I-270 to the Franklin/Delaware County Line

This might be the biggest surprise out of all the plans. The North Worthington Tunnel, the mini-dig, I-73 revisited all come to mind for me as I look at this plan. ODOT is proposing that "through traffic" along US 23 be routed underneith the current roadway as sort of a tunnel, or a trench/(long) cap design (as they put it). This trench would start just north of I-270 and end just north of Flint Rd. Meanwhile those needing access to Campus View Blvd, York Temple Rd, Vantage Dr, Crossroads Blvd, Flint Rd, and the Josephine would stay above ground. Sort of like a freeway (thus the I-73 reference).
