Hi all, first time making a topic. As the subject says, I was wondering about examples examples interstates where at least one direction only occupies a single lane (ramps included). For ramps, I know that 95 NB does one lane at the 93 interchange south of Boston...

...as does 55 SB at Crump in Memphis (NB's cloverleaf was widened to 2):

And in non ramp related instances, I-93 does a super two in Franconia Notch NH for environmental purposes:

Funnily enough, the southbound and westbound ramps are two lanes.
Interstate 705 Northbound in downtown Tacoma briefly has only a single through lane before an additional lane returns after the on ramp from SR 509. The lanes to the left exit into the City Center.

It's at least 2 lanes in each direction through Breezewood including the ramps at US-30.
At the Turnpike itself, it briefly is one lane through the interchange though for westbound traffic.

It's just for a moment, and even the sign isn't correct here. You're already on I-76 East, so you're not going "To" I-76 East.
I've always wondered if there was more significance to that "TO" than just a sign error, such as the Walt Whitman approach freeway on the PA side (DRPA owned?) not being formally I-76 or something like that....similar to that I-90 / Chicago Skyway thing.
Technically I-495's eastern end on Long Island (the ramp to Exit 73) is one lane, and is referenced marked as "495" to where it connects to CR-58. My point is the original alignment has the one lane where it can be at least two.
But I'll add my favorite one-lane Interstate highway: I-93 in northern New Hampshire. Such a beautiful ride through Franconia Notch
Technically, I-95 NB is one lane at the interchange to MA 128. If it had actually gone through Boston, this would not be the case.
I-90 is one lane each direction when it leaves the Berkshire Extension of the NY Thruway.
I-80 WB is briefly one lane on the approach to leave for the Ohio Turnpike (it becomes 2 lanes on the ramp)
I-293 becomes one lane for a few feet as it merges with the Everett Turnpike northbound. It also becomes one lane southbound as it merges with NH 101

I-293 becomes one lane for a few feet as it merges with the Everett Turnpike northbound. It also becomes one lane southbound as it merges with NH 101
I-80 WB is also on a one-lane ramp in Portage, Indiana, where it switches from the concurrency with I-90 (on the ITR) to the concurrency with I-94 (the Borman). In fact, I-80
EB is also on a one-lane ramp at the same location. Both are subject to significant backups.
I-80, when it jumps between the Indiana Toll Road and Borman Expressway in NW Indiana
Then I-80 again, as well as I-74, at their "bump" in the Quad Cities, IL area
I-72 at the NE Split with I-55 in Springfield, IL
I-74 at its Trumpet Interchange at the NW Split with I-55 in Bloomington/Normal, IL
I-39 at the US 20 Freeway south of Rockford, IL
I think that covers the IL examples. and also I-80 in NW Indiana for good measure...also is the only point in Hoosierland where I-80 isn't multiplexed with either I-90 or I-94
I mentioned it in the "sharp curves in Interstate interchanges" topic, but NB I-215's ramp as it segues from its multiplex with CA 60 onto the NB terminal segue from the CA 91 freeway in Riverside starts out as 2 lanes but shrinks down to one for the final and pretty damn sharp curve before merging. Apparently when D8 was planning the interchange upgrades in the late '90's they were going to raze the residential block on the northeast side of the interchange, but ran into a buzzsaw of opposition -- so the final plans essentially repaved the existing WB>NB interchange ramp but kept the same footprint. While not optimal by any means as the continuation facility for NB I-215, the saving grace is that it isn't generally a major commute movement, as much of the morning traffic from Moreno Valley/Perris-area residents either remains on WB CA 60 toward Ontario-area employment centers or turns SW onto CA 91 toward Corona and Orange County.
Both directions of I-35 at the east Mixmaster interchange in the Des Moines area, where it meets I-80 and the east end of I-235.

That is just bizarre. I'm glad you pointed it out because I never would've seen it otherwise.
For whatever reason, I looked back at the old Streetviews and discovered that button copy signage without yellow exit only panels was in existence until October 2018 (https://www.google.com/maps/@39.9279615,-75.1961155,3a,22.9y,137.69h,97.35t/data=!3m7!1e1!3m5!1svwhPh5tCCwvxzJIDK0ubjw!2e0!5s20181001T000000!7i16384!8i8192). Further east, the yellow overheight warning panel for the Penrose Avenue exit (https://www.google.com/maps/@39.9242386,-75.1927595,3a,75y,149.76h,91.43t/data=!3m7!1e1!3m5!1sxty4grHJHN36NjCqWDIpvQ!2e0!5s20160901T000000!7i13312!8i6656) wasn't installed until 2015-16.

It's at least 2 lanes in each direction through Breezewood including the ramps at US-30.
At the Turnpike itself, it briefly is one lane through the interchange though for westbound traffic.
On a related note, there's also I-70 at the other end of the Turnpike overlap in New Stanton, where the interchange ramps on either side of the toll plaza are one lane each direction.

I-81 in New York near the Canada border crosses over a two lane bridge - The Thousand Islands Bridge, which is actually a system of five bridges.
Ooh, nice! Forgot about that one. That's much more interesting than all the obvious examples through interchanges that are being posted.
I-695 in Maryland used to have "super two" sections on either side of the Key Bridge. The portion south of the bridge was dualized by the early 1980s; widening the portion north of it wasn't finished until 2000.
I-64 westbound briefly has a single through lane as it merges onto its concurrency with I-95 northbound in Richmond, VA.

Similarly the ramp carrying I-293 southbound from the Everett Turnpike to 101 east also narrows to a single lane.

Once the interchange is complete, I-99 will be a single lane when carried from the Bellefonte Bypass to the I-80 concurrency.
How would you classify northbound I-35 at the CBP checkpoint (https://goo.gl/maps/Vf3bF4MJH6LY5tF57) between Laredo and Encinal, TX? All traffic from the checkpoint funnels into one lane before resuming travel on the original mainline pavement. I believe this used to be striped as two lanes, but that doesn't appear to be the case anymore based on the most recent GSV.
I-84 eastbound exits onto itself at I-86 in Idaho, and the exit ramp is only one lane. They are currently rebuilding the interchange, but I don't think they're adding lanes. Can't tell, there's almost no info on ITD's website :banghead:
This portion of WB I-96 (https://goo.gl/maps/Gmc4xSHNesUciqvq7) has only one through lane briefly as the right of two lanes that continue past Exit 30B is an exit only to SB Alpine Ave. Not long after Exit 30B diverges, two lanes come in from (unsigned) I-296 on the left

If you follow that thru, you'll see it never actually reduces to a single lane, that sign notwithstanding.

What is stopping people from bypassing this checkpoint on the frontage road on the west side? The Google Streetview car even zipped past on this road. I assume they patrol this road and do spot checks? From looking at other checkpoints on aerials, the "bypasses" are generally pretty distant, unpaved roads, etc.

That's completely normal. The one north of Del Rio on US-277/377, for example, is a good 28 miles north of the border. The one on I-35 north of Laredo (which I posted) is actually closer to the border than the one on US-83.

You know, of all the times I've driven through that checkpoint, it's never occurred to me to ask that question. Yes, they patrol the roads, but that's still a great question.

That's completely normal. The one north of Del Rio on US-277/377, for example, is a good 28 miles north of the border. The one on I-35 north of Laredo (which I posted) is actually closer to the border than the one on US-83.
US-281 and US-77 both have them as well.
US-77's is 86 miles north of the border, and US-281's is 70 miles north of the border.
US-59 also has one leaving east of Laredo about 50 miles in.
This map (https://www.google.com/maps/d/u/0/viewer?hl=en_US&mid=1L872WkbWL11Zob-E9Oyk_Zen1Ws&ll=27.652133750311396%2C-87.30063492131666&z=5) has a list of all of them. I've been through the I-5 one north of San Diego on a college band trip, and I've driven through the US 77 one north of Brownsville.
It's been determined that border control can run checkpoints within 100 miles of the border. IMHO, this is a blatant 4th amendment violation and should be illegal, and that's not what the government thinks. /end political rant
That's not a very accurate map.
The one on I-35 north of Laredo hasn't been an inspection station for more than a decade. That location hasn't made sense ever since the Camino Colombia Toll Road was built. Also, the one on US-83 north of Laredo isn't shown at all, likely for the same reason.
The one north of Del Rio isn't shown at all.
The one near Comstock isn't shown at all.
And that's just the few whose locations I'm actually familiar with.

The map does not list the ones on US-59 or US-77, and the ones on I-35 and US-281 are in the wrong location.
I don't believe the facility on I-5 is in usage anymore. On Street View, it does not appear to ever be used, and when I drove through there a few years ago, I never had to stop. It's shown as a weigh station on Street View for tractor trailers.

I 15 in montana not only is one lane in both directions before and after it's concurrency with I 90, but it also technically exits itself off. same with I 90 east at the western I 94 terminus.
iirc I 80 west at the I 76 terminus goes down to a lane. I know for sure that I 80 east is one lane when it merges with I 76 traffic.

I-76 EB in Philly, going from the Schuykill Expressway to the Walt Whitman Expressway.
https://maps.app.goo.gl/QNYMe8QRVW79PSTT6
It's just for a moment, and even the sign isn't correct here. You're already on I-76 East, so you're not going "To" I-76 East.
I've always wondered if there was more significance to that "TO" than just a sign error, such as the Walt Whitman approach freeway on the PA side (DRPA owned?) not being formally I-76 or something like that....similar to that I-90 / Chicago Skyway thing.
Truth be told, and I chimed in on this on the thread that featured those replacement signs being erected, that
TO 76 reference likely dates back to when this stretch of highway was I-676 prior to 1973-74. Such met I-76 at the NJ side of the Walt Whitman Bridge at the I-76/676 junction.
The legends on the current signs 100% match those of the previous 1980s-vintage signs. I'd be curious to see what the much older predecessor signs, assuming such predated the I-76/676 switch, looked like it terms of legends & any alterations.
Such wouldn't be the only location where generations of replacement signs
still display old and/or incorrect information.
At least
three generations of this particular sign (https://www.google.com/maps/@42.403661,-71.0142883,3a,75y,295.83h,67.67t/data=!3m7!1e1!3m5!1sTcQFNl3zmnVuPgLO40NViQ!2e0!5s20190901T000000!7i13312!8i6656)
still showed the wrong/obsolete route number for the Revere Beach Parkway in Revere, MA. The route number changed from MA 1A to MA 16 circa 1971.
The GSV for this area was updated a few years after the prior one (https://www.google.com/maps/@42.4036718,-71.0144282,3a,75y,292.91h,74.92t/data=!3m6!1e1!3m4!1sKGukmMDQeGC_qINGZqYLHg!2e0!7i16384!8i8192) showing a new sign no showing a US 1 shield en lieu of a MA 1A shield. Such is
still incorrect; although a simple
TO could be applied to the left of that US 1 shield to make such more correct.

That's an interesting take, and I forgot about that switch. Maybe a shortcut of just shifting the "TO" from "676 TO 76" over to the left and it encompassed both for a time - "TO 676 76" (and was still technically accurate), and eventually of course 676 got swapped out for 95 which was finishing up on construction at the time.

I remember being shocked by that the first time I drove through that area. I would have thought those ramps would be plenty busy enough to be 2 lanes each, given that they carry mainline I-90. You have to think that traffic would heavily favor the I-90 movement at that interchange if it wasn't for I-480.

Probably the result of the counts being taken on different days, made obvious only because it's a partial interchange.
Seriously, though, it's not necessarily surprising that those ramps carry such low volumes, because of I-480. The more surprising thing is that I-90, the longest interstate in the country and the main E/W 2di powerhouse through the Cleveland area, is reduced, disgraced, and humiliated to the point of being

Used to be 2 lanes coming from both I-81 and I-40, then I-81 had a lane drop once merging.
Now it's 1 lane from I-40, 2 from I-81, and it continues as 3 lanes westbound.
I suppose while it reduces capacity for that ramp, traffic is lower coming from I-40 West compared to I-81 South, so it gives better flow for I-81 traffic merging in.
I couldn't imagine I-40 still being 4 lanes from Knoxville to I-81. When was it expanded to 6 lanes? IMO, they need to expand I-81 between I-40 and the Virginia state line to 6 lanes as well. It seems the majority of the traffic on I-40 East stays on I-81 North as opposed to turning east.

Makes sense to me. I-40 only goes to the Carolinas, while I-81 has tons of long-haul traffic as the main connection between much of the extended South and the Northeast. Basically every Southern state besides those on the Atlantic coast would use I-81 to get anywhere in the Northeast.

That's left over from when it was just the WK Parkway, although some work has been done on the southbound I-69 ramp to westbound I-24. It's doubtful that the amount of traffic has increased on those ramps since the WK Parkway became an interstate.

The Ohio Turnpike was fully completed by 1956 according to Wiki. Also, Ohio 2's freeway Elyria to Port Clinton was upgraded in stages from 1967-1990.
What was the purpose of building a parallel non-tolled freeway? And were there longer plans to Toledo? I guess I'm asking, was I-90 ever supposed to be on something other than the Turnpike? Would that explain the single lane ramp?
I personally like OH 2 between Elyria and I-280, and while I appreciate the Ohio Turnpike's design, the best service plazas IMO, and relatively reasonable tolls (I live in PA!), I usually take OH 2 when going West.

Can't say because I've never taken OH 2, but the two-lane portions look like they would be a slog in travel season.

Any increase of traffic won't likely come until I-69 is fully complete between Indianapolis and Memphis. Until then, I-70, I-57, and I-55 provide a faster, all interstate route.

I personally like OH 2 between Elyria and I-280, and while I appreciate the Ohio Turnpike's design, the best service plazas IMO, and relatively reasonable tolls (I live in PA!), I usually take OH 2 when going West.
Can't say because I've never taken OH 2, but the two-lane portions look like they would be a slog in travel season.
The Turnpike carries interregional traffic and is the only east-west interstate for traffic from Chicago to Cleveland and New York. Before its expansion to 3 lanes in the 90's and 00's it was scary to drive on when I was first learning to drive - heavy truck traffic, etc. Also, until the 90's, there were fewer exits than exist today. From the full movement interchange at OH 57, the next full exit was US 250 north of Milan (about 26 miles away), and then OH 53 in Fremont (another 26 miles). I grew up in Wakeman, and we had a 20 mile drive either east or west to connect to the Turnpike. It just was not built for local traffic.
Ohio 2 carries a lot of local traffic from Cleveland west through the Lorain County suburbs to the Lake Erie communities like Vermilion, Huron, and Sandusky (home of Cedar Point, the amusement park). It has the only bridge over Sandusky Bay (the next crossing is at Fremont which has to be used when the bridge is closed to fog). It connects to Port Clinton and Marblehead and to the ferries to South Bass Island and Kelley's Island. The last stretch of the freeway, the bypass around Huron, was completed in 1990 and had right of way reserved since 1970 but was delayed due to environmental concerns at Old Woman Creek. Before that completion, it was common for summer traffic to be backed up through the traffic lights in Huron heading to Cedar Point.
Regarding the two-lane portion west of Port Clinton and east of Toledo, that area in the former swamp is not vacationland. It's mostly farmland and sparsely populated until you get closer to Oregon. While it's a good connector to I-280 North and carries some commercial truck traffic, there's just not the traffic volumes to complete the freeway to Toledo. And, AFAIK, there never were plans to extend the freeway from its current terminus.

The OTIC would also likely throw a fit if the OH 2 freeway was extended.
I guess OH 2 serves a purpose similar to I-295 in NJ as a local alternate to the toll road. I didn't realize it was so rural between Port Clinton and Toledo. An argument could be made for extending the freeway, but it would mostly be a shunpiking-based argument because there's not much long-distance traffic and even if there was an extended freeway, the Turnpike would still be shorter and faster for most trips.

The Ohio Turnpike was fully completed by 1956 according to Wiki. Also, Ohio 2's freeway Elyria to Port Clinton was upgraded in stages from 1967-1990.
What was the purpose of building a parallel non-tolled freeway? And were there longer plans to Toledo? I guess I'm asking, was I-90 ever supposed to be on something other than the Turnpike? Would that explain the single lane ramp?

Someone correct me if I'm wrong, but I seem to remember previously reading somewhere (trying to find it) that I-90 was originally supposed to continue further west with OH 2 - and the exit 142 connector was built once it became clear that that wasn't going to happen.

Probably, but unless they have a legal agreement regarding competing routes like Indiana does, they can't do anything.

AFAIK, I-90 was always planned to exit the turnpike at Elyria. The first map that shows both I-80/I-90 on the Turnpike and the dashed under construction I-90 eastbound was this 1962 ODOT map (http://www.dot.state.oh.us/Divisions/Planning/TechServ/TIM/Official_Transportation_Maps/1962.pdf).
It appears that the current Exit 142 Turnpike eastbound to I-90 eastbound and westbound I-90 to westbound Turnpike connector was open in 1975 per the ODOT map (http://www.dot.state.oh.us/Divisions/Planning/TechServ/TIM/Official_Transportation_Maps/1975.pdf). Before the connector was constructed until about 2000, OH 57 was a limited access quasi-freeway between OH 2/I-90 and the turnpike, albeit with RIRO exits too close to the interchanges. That functioned as the connector for all movements and still handles all the remaining movements. I believe they built the connector so mainline I-90 wouldn't have to go through the then cloverleaf at OH 57 and double-trumpet to the Turnpike. I also think that was the first new location exit gate constructed on the Turnpike since its opening.
I don't think ODOT back in the day would have opposed moving an interstate off the Turnpike. That 1962 map showed I-80 following the current I-480 corridor through the Cleveland suburbs. And this 1964 map (http://www.dot.state.oh.us/Divisions/Planning/TechServ/TIM/Official_Transportation_Maps/1964.pdf) shows that as well but only US 6 on the Sandusky bypass (even while showing unbuilt I-90 east of there and even never-completed interstates like I-290 in Cleveland).
Granted, ODOT maps don't show every proposal ever made, such as the proposed extension of I-80S (now I-76) from its terminus west of Akron to the Turnpike in Milan following US 224 and US 250. I'd love to see some old logs from when the Interstate system was first proposed to see if there was even discussion of using that route. But, I assert any I-90 routing over OH 2 to Toledo hasn't been seriously contemplated since they started signing Interstates.
I-90 was always designated for the Ohio Turnpike, west of Cleveland.
1946

That said, ODOT, as recently as 1972, had thought of making Oh 2 an limited access highway all the way to Toledo.

Now, you kids are now asking, "why did Ohio want to have a freeway compete with the turnpike between Toledo & Cleveland?"
Because the Ohio Turnpike Commission & the Ohio Department of Highways were two separate entities for 35 years. Not until the 1990s and the Voinovich administration did the two start to work together (more exits along the turnpike and remember, I-73 planning in Ohio was under the Turnpike's auspices)

I-76 EB in Philly, going from the Schuykill Expressway to the Walt Whitman Expressway.
https://maps.app.goo.gl/QNYMe8QRVW79PSTT6
It's just for a moment, and even the sign isn't correct here. You're already on I-76 East, so you're not going "To" I-76 East.
I've always wondered if there was more significance to that "TO" than just a sign error, such as the Walt Whitman approach freeway on the PA side (DRPA owned?) not being formally I-76 or something like that....similar to that I-90 / Chicago Skyway thing.
And btw, just to be clear, there isn't a gap on I-76.
I-278 gets a single lane at the Grand Central split in Queens
