At-Grade Intersections with Exit Numbers

[Rothman]

Doesn't NY 9A/the West Side Highway in NYC have some intersections like this (at grade with exit numbers)? Maybe FDR Drive as well? Anyway, when I saw the thread title, that was the first thing that came to mind for me.

Mentioned twice in the thread already.

I believe the most common examples are on I-10, I-20 and I-40 in TX.

I don't remember seeing any of those having exit numbers.  Google link?

Ever since it corresponding cloverleaf movement was removed, I-55 South Exit 12B in Memphis has been converted into a left-turn intersection.  While it's on the off-ramp, it still has an exit number: https://goo.gl/maps/AWzU2cG4q3QJMnLn9

Not sure if this meets the topic at question but here's my example.

EB I-495 Long Island Expressway Eastern Terminus in Calverton/ Riverhead NY is signed as Exit 73 even though the expressway essentially just squeezes down to one lane and merges into CR-58.

Crap. That used to narrow down to two lanes. And no, that doesn't count.

Here's an at grade intersection at NY-347 & NY-111 in Smithtown NY. There's no exit number but there exit tab for N-S as there's a connecting ramp for all turns onto 111 to avoid turn movements at main intersection of 111/347. There a similar sign in opposite direction as well.

I fixed the link:

Your version was a zoom onto the asphalt.

I still remember at grade exit numbers on North Road(Suffolk CR 48, formerly CR 27) on the North Fork of Long Island, and on Suffolk CR 39 east of the end of Sunrise Highway, when NYSDOT was still hoping to move it on the extension east of Shinnecock Hills. Sadly though, I can't prove that they existed back then.

I've probably seen the advance sign for that, but I forgot all about it.  That one makes more sense than a lot of the others.

No exit numbers.

[oscar]

lots of them on I-90 in south Dakota & Montana & wyoming

Are those at-grade intersections, or are they normal exits where the only thing signed is the exit number?

None are at-grade intersections. Some in Wyoming have off-ramps posted for 10-15 mph exit speeds, but traffic on the local road passes over or under I-90.

Exit 16 and 17 (future 23D and 24) on CT 9 in Middletown.

[PHLBOS]

Although signage for such have largely gone by the wayside; MA 128 through Gloucester still has numbered intersections and one rotary... at least on paper.

9 - MA 127A intersection... MA 128's terminus
10 - MA 127 intersection
Blackburn Circle was not assigned an exit number
11 - MA 127 Grant Circle

Such has existed since 1962.  Note; MassDOT plans to drop these exit numbers for the above when 128 converts to mile-marker-based interchange numbers in the foreseeable future.

One sign that lists the above-exits.  Still there as of 2019.

Only remaining sign that the approaching Grant Circle is Exit 11.  Again, still there as of 2019.

Many semi-examples can be seen on the US 50 freeway in Maryland, in the Annapolis area - many of them *technically* have ramps, but they are so short (and the turns so tight) that they are at-grade intersections for all intents and purposes. The signs seem to indicate as much - notice that many of them use an arrow pointing straight right (or up and right) as opposed to the normal angled arrow.

An example from Street View (Exit 38A for Thompson Creek Road): https://www.google.com/maps/@38.9771093,-76.3141553,3a,37.5y,105.9h,93.85t/data=!3m6!1e1!3m4!1s2b4cMNbukzuOTk5g1u9qtQ!2e0!7i16384!8i8192

(It doesn't even pretend to be a traditional freeway exit - in fact, there is even a "right turn" marking on the pavement!)

[roadman65]

The Garden State Parkway used to have three of them in Cape May Courthouse, NJ before the NJTA had them all interchanged.

[KCRoadFan]

North of the border, I think I once read that there's a parkway-type road on Vancouver Island that marks some intersections with exit numbers. (Any users from BC, or who have visited, that can verify this?)

Some tighter ramps that are true exits can use these straight right arrows as well.

While it indicates a right turn here, many auxiliary lanes on interstates with true ramps also use right turn pavement markings. It's not uncommon.

Exit 1 of I-95 (now Exit 76 of I-295), southbound, used to be like that. It had the same horizontal right arrow, and the same pavement markings.

MA 140 Exit 1 (current and future)

The other end of the freeway as well, exit 12 (to soon be 20) has traffic signals for each ramp to 24.

How could I forget the exits for KY 66 and KY 118 on the Hal Rogers Parkway?

[DJ Particle]

Until the mid-1980s, the Orleans Rotary on Cape Cod was labeled as US-6 "Exit 13 N-S"

Exit 13S - MA-6A West/28 North
Exit 13N - Rock Harbor Rd

If they were still numbered, the renumbering project would have killed it, but if it was ever to be reconfigured as an interchange, it would likely be Exit 91.

That's not even the worst one! Exit 31 on US 50/301 in Skidmore is basically a direct turnoff, without even a curb to prevent overrun:

That's kind of scary.  At least they did a better job with the sharp turn-offs on I-68 in Cumberland: https://goo.gl/maps/hT64hyJqqnDYfUVF6
