Ohio

[Hot Rod Hootenanny]

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.

Is this near Kitty Hawk?

No. Between Rocky Mount and Battleboro.

Wow, I had no idea. Been a while since I've driven that way.

And another excuse for you to post an unrelated NC GSV link...

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.

By checking the more recent streetview, https://goo.gl/maps/ZF7buCN2n5Xznqpu5  the shape of that overpass speaks for itself and why they replaced it with a roundabout.

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.

Maine Turnpike had gone a step further, the former trumpet interchange on Maine Turnpike(I-95) with US-202 was replaced with a parclo A4. You can still see some of the old grading of the former ramps on this satellite shot. https://www.google.com/maps/@43.8821964,-70.3338813,807m/data=!3m1!1e3

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.

[vtk]

A trumpet interchange allowed consolidating the toll gates into one point at each interchange.

Exactly. On a ticket system this is the most cost-effective way of handling things.

Not to mention it was the best way to prevent most "illegal" mainline U-turns

[Buck87]

Regarding this new roundabout on 53, it's worth noting that 53 was a 4 lane road through the trumpet but narrowed down to 2 lanes immediately north of it.

I haven't seen the new configuration yet, but I'm guessing they didn't do a 2 lane roundabout and instead dropped 53 from 4 lanes to 2 lanes somewhere between Schwartz Dr. and this new roundabout.

Agreed. Time to fix the old substandard turnpike highways with all those trumpet interchanges.

There's nothing inherently substandard or wrong about a trumpet interchange. If it ain't broke, don't waste tollpayer money fixing it.

Trumpet interchanges like that actually may have benefits beyond the toll booth itself. By consolidating traffic to only one intersection, it can reduce congestion on the cross street caused by two signals being too close to each other. It also makes finding the on ramp easier, since there's only one and then you can decide which way.

I've built a handful of these on Cities: Skylines for this reason, and also since nowadays toll booths are available in game. 

[GCrites]

And remember, everything "old" is fine if the volume is low enough.

[PurdueBill]

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.  I always found interesting that the signs at the intersection (both directing traffic to the Turnpike as well as the directional signs at the intersection for exiting traffic) were button copy which was not the Turnpike's thing.  They must have had ODOT do those signs as they were on an ODOT road (just as on freeways the exit signs for the Turnpike exit are regular ODOT signs, with Turnpike-designed signs not appearing until on their property). Some of the latest button copy installed in Ohio still remains in locations like that (e.g., the OH 66 interchange opened in 1998 and has button copy signs at the intersection) and they still look good even at night. 

Until the bridges serving trumpets on low-volume interchanges reach the end of their service life, it doesn't make sense to replace them just because they are there "needlessly".  Building them originally was good future-proofing and when they run out of life, then alternatives make sense to consider.

It wasn't until I lived in Toledo in my college years that I discovered that there was one original turnpike exit on the Ohio Turnpike that did NOT have a trumpet interchange beyond the toll booth...Exit 34/Old Exit 3 in Wauseon, which was more or less a T intersection with SR-108.

And then I was surprised when I saw T-intersections at some of the New York Thruway exits, I guess I thought all Toll Roads were required to have Trumpet interchanges when I was a kid.

[GCrites]

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.

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