One Movement Only - Does it Exist Anywhere Else?

[Alps]

AZ US 60, WB exit 199: http://goo.gl/maps/1rRN8
PA I-78, WB exit 58: http://goo.gl/maps/0vhDs

While both near interchanges, they have their own exit numbers. Here's one that used to have its own exit number, until it was conflated with the next interchange to the east:

NJ I-80, EB Exit 34 (formerly 33): http://goo.gl/maps/PNDLq

So yeah, there are a few of these.

It happens again in Illinois on the Tri-State Tollway:

There are only southbound entrances from LaGrange Road (US-12/20/45) and Archer Avenue (IL-171).

These ramps are logically paired with the northbound exit to I-55.

No, these are not.  The ramps at Wolf Road are paired with I-55.  These used to have a northbound exit ramp until the late 1980s and were paired with 95th Street.

The Northwest Tollway has a westbound only entrance ramp from Devon just before the toll plaza.

There's no obvious counterpart here (though it also serves IL 72, which has two other ramps a bit to the west). Perhaps the intended way of reaching Devon from I-90 east is to loop around via I-190 and Mannheim.

Again, there are other ways of going onto the outbound Northwest Tollway from that point.  IL-72 (Touhy Avenue / Higgins Road) is served just as well by the set on the Tri-State Tollway at Touhy Avenue.  It's an extra ramp just as the ramp from Balmoral was until the exit ramp was built recently.

Huh? There's a direct ramp from I-294 north to I-55 north. There's no direct ramp from I-55 south to I-294 south. Wolf Road doesn't help make this movement. LaGrange does.

[roadman65]

What about the 39th Street exit off the Gowanus (I-278 Westbound) in Brooklyn, NY?  Its not paired with anything and it is solo, and only allows movement to WB 39th Street only even though 39th Street is two way.

Also, there is an exit off the Hill to Hill Bridge (PA 378 NB) for Main Street in Bethlehem, PA that has no logical counterpart being the ramp leading on to the bridge was barricaded off years ago.

I-35 has this odd little one in OKC.

Yes, it does, but it is not a part of the I-55/I-294 interchange.  It is a completely separate ramp with a bit of a "Breezewood" between the two.  The Wolf Road interchange is part of the original interchange there at I-55/Joliet Road.

[NE2]

Yes, it's a separate ramp that's logically paired with the 294 north to 55 north ramp. You're looking only about physical location, not logical movements.

[kphoger]

All right, it's a very marginal example.  I see both sides of the argument.  Actually, I'm glad the example was given, because it made me think critically about what qualifies as a "movement" (no poop jokes!).

Surely there are more examples to find, though.   ?

[amroad17]

This could marginally count as "one movement only":
NY 695 outside of Syracuse with the Gerelock Rd. exit and Horan Rd. entrance ramps seemingly independent of each other.

[roadman65]

In South Amboy, NJ you have one off ramp from Northbound US 9 & NJ 35 that goes to CR 670.  There is no logical counter part to this. 

[TheHighwayMan3561]

Winter St. to westbound US 2 in Superior, WI.

Okay my turn.

Mayfair Road exit from US-45 http://goo.gl/maps/kCjNL ...Full interchange with North Ave close by though.
Port Washington Road exit from I-43 http://goo.gl/maps/PvVRl

Only ones I can think of right now.

OH 315 southbound to US 40 / Broad St in Columbus.

There is not a southbound entrance ramp.  There is not a northbound exit ramp.  There used to be a northbound entrance ramp, but that's been gone at least 20 years now. 

To top it all off, you can't even legally exit from the mainline of OH 315 to Broad St using this ramp.  In order to use the ramp, you must have entered OH 315 southbound from I-670 or US 33 at the previous interchange.  This restriction has been present since circa 2001.

Across the street from the end of this ramp used to be a Ford dealership, which was closed as part of the reorganization associated with the auto bailout.  Not really roadgeek-relevant, but continuing on the theme of a series of closures...

I-86 and Chemung CR 74: http://goo.gl/maps/oT5Tw

[PHLBOS]

There is an entrance to I-84 westbound from Mashapaug Road south of Sturbridge, MA.

Forgot about that one.  IIRC, that was once MA 15.

I-95 exit 10 near the Philadelphia Airport consists of one ramp to PA 291 eastbound from I-95 northbound.

Given that one is practically in my backyard, I'm surprised that I forgot that one.  Blame it on still adjusting to Daylight Savings Time lol. 

There is an entrance to I-95 northbound from Castor Avenue in Philadelphia.

As with the fore-mentioned Clarendon St. entrance ramp to I-90 West in Boston (my bad on considering that independent of Exit 22), that I-95 North entrance ramp is likely considered to be part of Exit 25 (Allegheny Ave.).

Canton, MA: On-ramp to I-95 South from Dedham St., located between Exit 11 (Neponset St.) and Exit 12 (I-93 North).

What about the 39th Street exit off the Gowanus (I-278 Westbound) in Brooklyn, NY?  Its not paired with anything and it is solo, and only allows movement to WB 39th Street only even though 39th Street is two way.

....

I thought about that one, but I didn't think it met the criteria because there's an exit ramp on the other side at the same place. It doesn't connect directly to the same street, but it's within about one block. Certainly an example of limited connections, at least.

[kphoger]

Okay my turn.

Mayfair Road exit from US-45 http://goo.gl/maps/kCjNL ...Full interchange with North Ave close by though.
Port Washington Road exit from I-43 http://goo.gl/maps/PvVRl

Only ones I can think of right now.

I'd say both of those are examples where they simply split an interchange up due to the proximity of the other road(s).  In the first one, the ramp is simply providing the missing NB>EB movement at the North Avenue exit.  In the second one, the ramp functions as the mate to the SB entrance from County Line Road

I-95 exit 12 in Virginia: http://maps.google.com/maps?hl=en&ll=36.725522,-77.527374&spn=0.007843,0.016512&gl=us&t=k&z=17
This used to be the north end of the Emporia bypass. There is, however, a full interchange just to the north now.

I-95 exit 17 in Rhode Island: http://maps.google.com/maps?hl=en&ll=41.787553,-71.419748&spn=0.007296,0.016512&gl=us&t=k&z=17
Other movements can be made using RI 10 to the south.

I-469 exit 31C: http://maps.google.com/maps?hl=en&ll=41.170772,-85.108101&spn=0.014731,0.033023&gl=us&t=k&z=16
Other movements are via I-69 and Dupont Road.

There are a fair number on roads that were upgraded on the spot where a bypass begins or ends, such as SR 99 in California (e.g. both ends of Traver).

On I-78 at Emaus Avenue in Allentown, motorists are treated to an off-ramp from the highway to southbound on Emaus – and that's the only movement available. You can't get off the highway northbound, nor onto 78 from either way on Emaus Avenue. Why bother with (and spend the money on) a one-ramp "interchange"? I'm unaware of any major traffic generator – a business, sprawling school complex, warehouse park or whatever – south of 78 that would justify the lone off-ramp.

I-390 and Monroe CR 85: http://goo.gl/maps/Z0II0

Nah, that's logically paired with the on-ramp from East Henrietta Road, because the off-ramp there is pretty much out of the question at rush hour!

[algorerhythms]

I guess if we're trying to list all of them... there's one on westbound I-68 at Exit 41 (Seton Drive). It was to provide access for ambulances to get to (the now-closed) Sacred Heart Hospital in Cumberland.

Landers Lane off I-295 North in Delaware into a residential neighborhood.  The exit gore sign even lists all the developments one can access off the exit.

This looks like a silly example by the author of the article. If you zoom out a bit on the GoogMap, you'll see that the ramp in question makes up for a missing movement at the Lehigh Street interchange. The ramp could not be easily built at Lehigh due to nearby structures. Duh!

I'd consider it a single movement exit.  While the main purpose of the ramp may be to offset MCC traffic from NY 15A up north, I use it to get gas when I'm home (BJ's in Henrietta is the cheapest gas in the entire state), and while I can take I-390 to get there, I can't take any freeways on the way back.  It's too bad - it would save a bit of time to be able to bypass Clinton Ave and Westfall Rd both directions.
