Ohio

[Ted$8roadFan]

Just goes to show how few exits the Turnpike had initially that Exit 34 was old Exit 3. That is a very long way between exits for Ohio. There's a sign on I-70 west near Zanesville that warns you that it is a whole nine miles to the next exit.

Originally it was only 16 exits, now it's up to 30

Note: may have been a few more than 16 originally, I'm not quite sure if the partial exits for I-90, I-480 and I-680 with old numbers 8A, 9A and 16A were original exits that were given letters because they were partial exits, or if they came latter like all the other A and B exits that were added between the original construction and the switch to mileage based exit numbers.   

IIRC, the addition of new exits was a key reason why the Turnpike switched to mileage-based exit numbers in the late 90s/early 00s.

The Turnpike was built in the mid-1950s. Those partial exits were later additions.

I want to say the first "new" exit that was built was a little over 20 years after the Turnpike opened -- and IIRC, it was Exit 8-A, the connector to SR-2 (and later I-90 once it was fully completed into downtown Cleveland).  I-680 and the I-480 partial exits came soon after.

As time passes, those older interchanges that had trumpet ramps and single ticket/cash tollgates for traffic getting on and off of the highway can be replaced with more conventional diamond, par-clo and other needed connections with transponder gantries, including at newly added local access interchanges, as needed.

There's a sign on I-70 west near Zanesville that warns you that it is a whole nine miles to the next exit.

And yet there's no such warning for the 14 mile gap on I-71 between SR 95 and SR 97

[GCrites]

Different District?

[Buck87]

Different District?

Yes.

The Zanesville area example is entirely in District 5

The OH 95 end of I-71's 14 mile stretch is in District 6, while the OH 97 end is in District 3.

I couldn't figure out how to get Google Maps to show counties today.

Much less the 12 miles between I-270 & 36/37 back in the day (Pre Polaris)

It doesn't.  Third parties have added the layer (e.g. at mob-rule.com).

If you search for a specific county, it will outline that county but the outline goes away as you zoom in close.

Ah, true.  It's functionality is so limited, I dismissed it out of hand.

The more recent Turnpike interchanges in western Ohio were built from scratch with intersections instead of trumpets like they would have been if they were original to the road, probably because of the low-enough volume and it being cheaper.

One of the most welcome new interchanges was Exit 52, for SR-2 and the Toledo Express Airport (TOL).  It was built with an intersection, complete with a 4th movement leading right into the airport.  Now if it were a major airport, an overpass and interchange with SR-2 would be a given.  But TOL is currently served by only TWO airlines, having long since been eclipsed by Detroit Metro (DTW), which the construction of I-275 made it easier for Toledoans to get to.  Even with the Turnpike exit, access to TOL is still a little roundabout; see this post for details.

[Buck87]

I was in Fremont today so I took a slight detour north to check out the new roundabout at OH 53 and the Turnpike.

As you approach it on 4 lane 53 going northbound, the left lane is signed for the Turnpike and the right lane is signed for 53 north. Both lanes enter the roundabout, which has two lanes just on that side until the right lane splits off to 53 north. The rest of the roundabout is one lane. 

Whatever paint they used for the white lines is already really badly faded and needs redone. Not sure what the deal is there, it was just installed sometime last year.

A DDI was the popular option at an ODOT public meeting about possible changes to the I-75/US 20/US 23 interchange in Perrysburg:

Too bad it wasnt so built up against the current interchange ‐‐ a DDI SPUI would be the best option if there was room.

The US-20/23, I‐75 Perrysburg area reminds me a lot of the US-30, I-65, Merrilville IN mess with a major, truck-heavy US highway from the east having to traverse several miles of heavy traffic, signals and retail before being able to reach the freeway.



Mea Culpa...meant to originally say a SPUI would be a better option in Perrysburg if the space was there and they were willing to rebuild the I-75 mainline bridges there at the same time to accomodate.

It looks like the only property obstacle is the Burger King. Am I missing something? It's not like a DDI needs a huge ROW as shown here or here.

[tigerwings]

The BK would need to go for the DDI.

The Harley shop west side may need to go also. It would be a tight turn for trucks.

Also:

Too bad they didn't make the I-475 to NB I-75 exit a fly over instead of dumping into the left hand lane went to changed this years ago. Traffic needs to cut across 2 lanes quick to get off at US-20. Add to it the weaving from 475 to SB 75 with traffic from Dixie Hwy, ODOT needs to try again on this interchange

I fail to see how either of these facilities would need to be moved.

Reminds me of OH 32 for the first few miles east of I-275 as well. Good thing that the remaining signals between 275 and Batavia are planned to be removed at some point.

Possibly, and I would definitely agree if the interchange were being built from scratch now.  But how much traffic is actually making that maneuver?  That's part of what goes into the decision of whether the cost to modify the existing interchange is justified.  That it's the routing of sbd US-23 isn't enough on its own.

I went to a zoning meeting in Pickaway County this week and the township Zoning Director said that ODOT told him that the U.S. 23/OH-762 interchange is project is two years away from construction and that a much-needed roundabout at OH-762 and Ashville Pike/Duvall Road is one year away.

Nice. I suppose these are both being done due to truck traffic going to and from the NS Rickenbacker intermodal terminal and other industries in that area. 

[GCrites]

Yes, for current and future growth. There are a lot of projects in the design and construction phases in the vicinity.

Some more information: https://www.morpc.org/wordpress/wp-content/uploads/2017/12/PIC_Pickaway_County_Transportation_Improvements.pdf (from 2017) and what the
interchange could look like: https://ashvilleohio.gov/images/wastewater-facility-expansion/appendix%20f.pdf

I still wish I could find the plans for the South Bloomfield bypass online.

Two interesting finds in a Cincinnati city storage lot this evening:

A very recent-looking Cincinnati Gardens sign from SR-562...


...and a cache of Cincinnati's well-known yellow lamps, which have only gotten more scarce over the past decade or so.
