On the topic of roundabouts, there are a lot of them in the works in Ohio. I did a ctrl+F for "roundabout" in the STIP document and thought my laptop was going to crash for a second while the search loaded.

Some noteworthy ones planned for the next 1-3 years in northern Ohio that caught my eye:

OH 18 and OH 601 east of Norwalk. This is right next to Summit Motorsports park and an R&L Trucking distribution center and is just down the road from the previously discussed roundabout at US 20 and OH 601 that opened last year.

US 250 and OH 60 on the north side of Ashland. This is at the northwest end of Ashland's 2 lane bypass. There's also a couple planned on US 42 further northeast of Ashland at OH 89 and OH 302.

US 6 at Cedar Point Dr in Sandusky. This one will be interesting as it butts right up against Pipe Creek/Castaway Bay as well as some local business parking lots including the Thirsty Pony/Cedar Lanes complex. This intersection handles the vast majority of traffic going to and from Cedar Point. 

OH 4 and OH 99 about a mile north of the Ohio Turnpike. OH 4 gets very busy in the summer with Cedar Point and general Shores and Islands area traffic.

OH 18 and OH 511 in the unincorporated village of Brighton. Two churches are there across road from each other, but sit far enough back that it shouldn't be a problem. 

OH 163 and North Shore Blvd/Englebeck Rd west of Marblehead. North Shore is the main road going back into Lakeside.

OH 113 and Baumhart Rd, 1 mile south of Baumhart's Ohio Turnpike exit.

SR 83 and Chestnut Ridge Rd in North Ridgeville. There's a nice bar there called 83 and Chestnut that I hope survives.

US 224 and OH 587 between Tiffin and Findlay.

OH 98 and OH 597 north of Waldo.

Look at the cities beyond US 35 for why it got upgraded to 4 lanes, not just what’s on it.

And that's exactly my point. Connecting Columbus, Dayton and Cincinnati to Huntington/Ashland/Ironton seems like it wouldn't be a bad idea. US 35 is a good road to Charleston, but you have to backtrack to get to Huntington.

[seicer]

There just isn't demand. OH 7 south of Gallipolis drops to under 2,300 VPD, and the initial phases of the Chesapeake-Proctorville bypass are being built to two-lane limited-access standards with the ultimate goal of building out to four lanes with interchanges - but that's mostly because the area is a bedroom community for Huntington.

On the West Virginia side, WV 2 drops to around 3,500 to 4,500, depending on how close to Huntington or Point Pleasant you are. The new Nucor plant will add some traffic but not enough to warrant four lanes. There are long-range "plans" to widen all of Route 2 to four lanes but that's gotten nowhere except for at its northern reaches. Parts of the route in Cabell County are built on a four-lane right-of-way but that's about it.

I live in the Tri-State area and frequently go to Columbus. US 23 is the preferred route and it takes about 2.25 hours via US 23 and OH 823. With the Portsmouth bypass in place, there is no need to traverse steep and winding two-lane roads. If I'm going to Dayton, I take US 23 and US 35 as those are essentially all freeways or expressways. Cincinnati? US 23 to the AA Highway (2 hours) or US 23 to OH 73-32 (2.25 hours) or OH 32 (2.5 hours).

US-23 is just as adequate of a route as US-35 is. Why wouldn't one just take that?

How is there that many accidents for that interchange set up? The west end - with an intersection thrown into the middle of it, looks more suspect. I don't mind roundabouts, either, but from a 65 MPH freeway? That seems like what is proposed for the Chesapeake bypass - a limited access 55 MPH expressway with a roundabout dead center.

How is that really any different from the current traffic signal another 1/2 mile farther along (at Shock Road/OH-19) from a 65 mph freeway?

The problem is with EB drivers going from the bypass directly into the roundabout

I understand what you are saying.  My point is that EB drivers currently go from the bypass directly into a traffic signal.  I don't think adding a roundabout only 1/2 mile before the signal adds any additional hazard.

I know there's a light not far beyond the proposed roundabout EB. However, a stop light may force a driver to slow down. A roundabout forces a driver to slow down. Not a big deal for drivers in cars. But for trucks, it's a big deal. It's not a problem for EB trucks as there is a bypass for the roundabout for drivers bypassing Fremont.

Also, the speed limit is 65 mph EB going into the roundabout. It's 60 mph WB (and that's after the stoplight and only for drivers entering Fremont). Not much difference, but every little bit helps. Especially as Ohio drivers are likely to know 65 is the typical expressway speed and any lower speed could mean obstacles like stop lights.

I agree that it's not much distinction. I've dealt with roundabouts in the middle of nowhere when I've gone back to visit relatives in Wisconsin. I didn't like them either. And I usually like roundabouts.

[sprjus4]

^ Except for highways in the eastern part of the state, which may be wide open expressways with little obstacles easily traversable at 70+ mph, however are all capped at 60 mph simply due to low traffic at-grade crossings.

OH 163 and North Shore Blvd/Englebeck Rd west of Marblehead. North Shore is the main road going back into Lakeside.

I'm glad to see they are finally doing something for that intersection.  I personally had been thinking a  signal and dedicated turn lanes, but I think a roundabout will work well there.

OH 98 & Oh 529 or Oh 98 & Oh 598? There is no 597.

529. That was a pretty bad typo.

A roundabout was just completed end of last year at the Ohio Turnpike's exit 91, replacing the trumpet interchange at OH-53.  I'm guessing the bridge was in need of replacement and it was decided to eliminate it instead, but with a roundabout instead of a signalized T-intersection.

Definitely a downgrade. I have a feeling something like that could happen here as well. Used to serve I-95 traffic but its relatively quiet here now.

If it's "relatively quiet" then maybe it's not worth the money to replace structures supporting high traffic volumes that don't exist.

Yes, but he does have a point. His example is another interchange (the NC example is a partial interchange) that will probably not be retained when the life of the bridge is ending. I could show a similar example in my old home town where a partial was built that is no longer needed. I can easily imagine a roundabout here knowing WISDOT's penchant for building them.

The OTC was starting to redesign and replace some of the trumpet interchanges as early as the mid 90s, when the original pre-I-71 Exit 10 trumpet interchange at US-42/Pearl Road was turned into a signalized "T" Intersection.  You can still make out the original footprint  in this GSV.:

Yikes. That entire pier was cracked and splitting.

New York has a number of ramps that have been removed, notably because they didn't serve that much of a purpose on lower volume roads, and because longer-term plans to convert roadways to free-flowing highways were canceled.

I think it's time for NJTA and MassTA to invest in converting the interchanges on the NJ turnpike and the Mass turnpike to those.

I've often said that, in the heyday of turnpike/toll-road construction in the 50s, there was a tendency to connect the surface road with a trumpet interchange by default, even if it was really not needed.  Hence, these and others have been replaced with signalized intersections.

Not all of them get a trumpet-to-trumpet connection right from the start. Exit 8A in the NJ Turkpike (I-95) was a trumpet-to-T intersection who was replaced by a trumpet later when the trafic levels raised. http://mapper.acme.com/?ll=40.35127,-74.47228&z=15&t=U

[The Ghostbuster]

Why were so many toll road interchanges built as trumpet interchanges on both ends? Wouldn't standard diamond interchanges have sufficed? Seems like a waste of land to me.
