Typically on 2 lane roads that pass from one state to the other at the state line but could be other types of roads as well.
Texas-Louisiana - 70/55 (Maybe 75 on some road in east TX that crosses into LA)
Oregon-Nevada - 55/70
These are two examples that come to mind.
I'm not sure it's exactly at the state line, but when you cross from the Hutchinson Parkway in New York to the Merritt Parkway (CT 15) in Connecticut, there's a curvy stretch just over the border where the speed limit drops from 55 MPH to 45 MPH for a little while.
I have not field-checked these, but given the statewide default differences between the Dakotas (65 MPH) and Minnesota (generally 55 MPH), there could theoretically be 10 mph differences at these outside-an-adjacent-town locations:
- MN 269/SD 11
- MN 30/SD 34
- US 14
- MN 19/SD 30
- MN 271/SD 28
- MN 68/SD 22
- US 212
- MN 40/SD 20
- MN 55/ND 11
- MN 200/ND 200
- MN 317/ND 17
- MN 11/ND 66
- MN 175/ND 5
Within 3 miles of the CT/MA border, the speed limit on I-91 N drops from 65 to 45 for the Forest Park curve in Springfield.
IIRC, when I drove it in early 2008, US 62/180 dropped from 75 to 55, crossing from Texas east of El Paso into New Mexico. Now GMSV shows the drop is only down to 70, with the highway changing from two-lane to four-lane divided just after the state line.
Due to the various agencies that operate the toll bridges crossing the Delaware River which base their speed limits on arbitrary figures rather than actual engineering, one will find speed limit drops as you get close to the border. Taking the NJ Turnpike south, the limit drops from 65 to 50 mph at the Delaware Memorial Bridge. I-76 drops from 55 to 45 mph approaching the Walt Whitman Bridge. On I-676, the limit was 55 mph up to near the toll plaza. Apparently the DRPA took over a little more jurisdiction of I-676 in NJ, because they posted 45 mph limits on 676 where it had been 55 mph forever.
I seem to recall US-15 dropping from 65 in Pennsylvania, where it's a freeway around Gettysburg, to 55 in Maryland.

That speed limit drop (currently) happens before the state line:

I noticed that as well. I see DRPA cops patrolling 676 north of Kaighn's Av all the time these days.

Not state line, but county line, on Church Road as you enter Burlington County from Camden County, the speed limit goes up from 25 to 40: https://www.google.com/maps/@39.9316524,-74.9824522,3a,75y,83.7h,69.82t/data=!3m6!1e1!3m4!1speUL2QbZiwtn6ih1ZN_Ykw!2e0!7i13312!8i6656!5m1!1e1!6m1!1e1
Well, probably. That is the first 40 sign going eastbound, but the first 25 sign going westbound is not until after Kings Highway. Curiously, Greentree Road goes the opposite way, 35 to 25 from Camden to Burlington County (https://www.google.com/maps/@39.9059785,-74.9527659,3a,75y,83.66h,81.2t/data=!3m6!1e1!3m4!1ssjQxRfeAVwBU0W2akE-L_g!2e0!7i13312!8i6656!5m1!1e1!6m1!1e1).
US 4 at the NY/VT line has a 10 mph drop/increase within 1/4 mile of the state line. NY/MA 2 has a 15 mph drop at the state line heading EB (25 for trucks).
I don't think this was mentioned yet, but I-95 at the DE/MD line.
Quote from: cl94 on December 07, 2015, 01:02:28 PMI don't think this was mentioned yet, but I-95 at the DE/MD line.
Not anymore. I-95 from the Maryland line to just past the I-495 split is now 65.
US 19 across the FL/GA State Line goes from 65 mph in Florida to 55 mph in Georgia.
US 1, 23, and 301 do the same at the FL/GA State Line (St. Mary's River) where GA keeps what FL does at 65 at 55.
The US 1 crossing has an excuse because Folkston lies within a few miles of the border which has lower speed limits than 55 anyway. US 19 has over 10 miles of rural road, which is 65 mph elsewhere on four lane roads like itself usually, before it reaches Thomasville, GA its first city along the way.

That's how I've always understood it because the northbound limit changes pretty much right after you cross the state line.

The inverse happens going from Maryland (65) to PA (55) on I-70. That 55 mph stretch in PA is utterly pointless.
Speed limit on US 460 in West Virginia east of Princeton drops from 65 to 45 at the Virginia state line. I actually think the drop was to 35 at one point.
It's worth noting that the speed limit on US 95 at the Oregon/ Idaho line is currently 55/65, where one speeds up 10 MPH entering Idaho.
Come this spring, it will be 70/65, so crossing from Oregon into Idaho will actually require slowing down 5 MPH.
-Until the New York section of I-99 opened, US 15 was 55/65 at the NY/PA line, dropping NB. If the drop wasn't right at the line, it was pretty damn close.
-NY/VT 149 is 30/40
-MA/NY 23 is 30/55
-I-70 at the OH/WV line is 65/45, respectively. I don't know if ODOT raised that stretch to 70, so it might be more.

I don't think I saw this mentioned above, but I-84's speed limit also changes at the OR/ID state line, from 80 mph in Idaho to 65 mph in Oregon, a 15 mph difference. It's a very lurching slowdown. As corco mentioned above time-wise, Oregon should be raising I-84's speed limit to 70 mph east of The Dalles, which I believe takes effect on 1 March 2016. If ODOT had its way I bet they'd want to keep the easternmost few miles inside Ontario set at 65 (due to the couple exits within a mile or two of each other) but the law might preclude them from setting a limit lower than 70 there.
From a vague memory, US-491 South goes from 65 MPH in Colorado to either 50 or 55 at the border with New Mexico.
The strangest part of it all is that when you cross into New Mexico, despite no lane additions or drops, the NM side of the border is more barren than the CO side, and yet that is where the slower speed resides.
I-20 drops from 70 mph to 55 mph westbound at the AL/GA state line, because the concrete pavement on the AL section was falling apart and rather than fix it short-term they thought lowering the speed limit would make the next time a chunk flew up off the road into a car's windshield non-lethal.
Now it's a construction zone technically, although in ALDOT's typical fashion it's completely half-assed with a lengthy portion that's been widened to six lanes but blocked off to traffic for no apparent reason (and the 55 mph work zone limit still in force, naturally).

I live in Huntsville and once took I-20 as part of a drive to Atlanta. I saw that 55 mph limit and was like WTF. ALDOT (or ALDONT as many call it) has to be one of the worst DOT in the nation.

Last I saw (March 2014), it had changed from 65 to 50(looking at Street View it had changed before 2009). The US 460 Blacksburg/Christiansburg Bypass also now ends eastbound with a 65 to 50 to 35 drop.

- MN 200/ND 200
- MN 317/ND 17
- MN 11/ND 66
- MN 175/ND 5
Minnesota is raising the Speed Limit on many 2 lane roads to 60. US 212 is one of them, and streetview confirms that the speed limit is 60 when crossing from South Dakota to Minnesota. Over a 5 year period, MNDOT will be studying all roads that have a 55 mph speed limit to see if they should be raised to 60, and the study started in 2014. I personally drove MN 7 across the state a few years ago and it was signed at 60.
KS 171 to MO 171 drops from 65 to 55 when crossing into Missouri.
I-90 going between Minnesota and South Dakota is changing between 70 and 80 MPH.
* Although it appears to be a bit south of the state line, I-74 goes from 65 in Illinois to 50 in Iowa Streetview (https://www.google.com/maps/@41.5115975,-90.5125755,3a,75y,143.97h,70.78t/data=!3m6!1e1!3m4!1s7aF35EGcT_T5uPTHMEyGkg!2e0!7i13312!8i6656?hl=en)

I-90 drops from 75 to 55 moving from Montana to Idaho (unless this has changed somewhat recently), a 20 MPH difference. Yes both states have a maximum of 80, but Idaho is much more "gung-ho" about lowering the limits from the maximum than Montana is.
Entirely due to different states' speed limit laws:
US 30 IN/OH (60/70 MPH)
I suspect the same on US 24, but I have not personally observed it.
Urban/rural:
US 23 and I-75 are both 70 MPH in extreme southern Michigan, certainly lower across the border in Ohio, though I can't remember if it's 55 or 60 or 65 MPH just inside the Toledo metro area.
US 190 at the Texas/Louisiana state line there is a 20 mph speed difference.

Yep, and to add to that, US-12 goes from 70 to 50 crossing from Montana into Idaho.
I-81 (NY)/ON 137: 65 mph to 50 kph, with a brief NB 40 mph zone for customs.
Maryland to DC on Pennsylvania Avenue, speed limit drops from 45 mph to 30 mph. It's not an unreasonable drop due to the road narrowing combined with parallel parking, but DC gives drivers the finger by putting a speed camera within a block or two of the line.
NY/CT is good for these.
NY 433 has a speed limit of 45. Upon entering Connecticut (and becoming locally maintained) it drops to 35. Which is damn exceptional because you will rarely see a town maintained road in Connecticut posted higher than 30.
The speed limit on NY 35 approaching the CT state line is 55. Once you enter Connecticut, the limit drops to 40. Half a mile later, it drops to 30. Granted, the road on the Connecticut side is curvier than the road on the New York side and does legitimately justify a lower speed limit, but it doesn't need to be rapidly ratcheted all the way down to 30 except because Connecticut.
NY 116 is 45, CT 116 is 35.
NY 343 is 55, CT 343 is 40.
Inversely, CT 123 is posted at 45 but drops to 35 upon entering NY.

Huh, I was expecting to find that this was wrong, but I now see that they bumped the western section of US 30 to 70 mph back in June (http://limaohio.com/news/6069/speed-limit-on-u-s-30-bumped-to-70-mph). When they first made the jump to 70 for non interstate freeways in October of 2013, the only part of US 30 west of I-71 that qualified was the section from Mansfield to Bucyrus....so I'm pretty damn surprised that they have now decided to make it 70 on sections that still have at grade intersections. So now US 30 is 70 mph from the Indiana line all the way to the edge of Mansfield, with the exception of the multiplex with US 23 around Upper Sandusky.

Redoing my post, I-78 EB goes from 65, then suddenly becomes 55 after entering NJ. WB goes from 55 until MP 1, and then for the last mile I-78 WB is briefly 65 before being reduced to a speed limit of 5 because of the toll after the bridge. I may be wrong though.

I-78 is normally 65 right thru the state line between PA & NJ, although construction had the limit temporarily down to 50 in NJ. At the toll plaza, the express EZ Pass should be supporting 65 thru the lanes. Amazingly, GSV hasn't been updated since 2008 near the toll plaza.
Carretera Federal 85, between the states of Tamaulipas and Nuevo León: 100 km/h versus 80 km/h, for an equivalent difference of approximately 12.4 mph. I don't remember, offhand, which state has which limit.
Forgot an obvious one: US 78 drops from 70 mph to 55 mph at the Tennessee state line, although that's more due to the change in access control from "full" to "barely any" a few hundred feet into Tennessee.

For all of New York's insanely low limits in urban areas, a speed limit under 55 is typically reserved for developed areas. A winding road on a mountain will often be 55. Almost every state line crossing out of New York on a local road in terrain that isn't relatively flat has a drop of at least 5 mph. I'll add NY 26/PA 267 and NY 79/PA 92 near Binghamton (55/45)
As for dropping when one enters New York, there are very few. There's CT 123, VT 149, PA 191 in Hancock (30/45), and the two tunnels into Manhattan.
US 59 where it straddles Texas and Arkansas north of Texarkana. Southbound 59 has a 75 mph limit since its on the Texas side and 65 mph on the northbound lanes due to it being in Arkansas.

Is there anywhere else where two sides of the same road have a different speed limit? I remember once upon a time this was the case on I-79 between the WV line and I-70, due to a mine subsidence problem, but not sure if it's the case or not.

How long of a distance are we talking about? New York typically drops limits to 55 before the end of an expressway in the direction approaching the end for a mile or so.

I-89 in Bow, NH is an answer along the same vein. The speed limit drops at the end as it comes to I-93 (where it goes past to actually end at a traffic light)

Is there anywhere else where two sides of the same road have a different speed limit? I remember once upon a time this was the case on I-79 between the WV line and I-70, due to a mine subsidence problem, but not sure if it's the case or not.
I-65 immediately north of Montgomery had that. Northbound was 70 mph after you crossed the river and southbound was 60 or 65 in the same area (don't remember which). Don't know if it's still like that. The reason had to do with southbound traffic entering an area with multiple interchanges in a short stretch.

Not a numbered highway, but there was a 2-lane road in Northeast Ohio that straddled two municipalities (West 130th St. north of SR-303). Northbound/Hinckley Township was 45 MPH, Southbound/Brunswick City was 35 MPH. Not sure if they ever settled on a uniform speed limit, but these dual-limits were in place for many many years as late as the early 00s.
Which begs the question: If you were passing someone going the speed limit entering into the other municipality, would you be passing at the other's legal speed limit or "speeding" in the other municipality, depending on the direction you are going?

On US-460 between Narrows, VA and the WV line, the curvier westbound lanes have a limit of 40 MPH, whereas the eastbound lanes remain at 60 MPH.

I've posted previously unintentional situations like this, both on NJ county routes. In one, the last Speed Limit 25 and first Speed Limit 40 are a few blocks apart implying that it's 25 in one direction and 40 in the other. In the other, the speed limit was lowered from 50 to 40 in one direction, but not the other.

Redoing my post, I-78 EB goes from 65, then suddenly becomes 55 after entering NJ. WB goes from 55 until MP 1, and then for the last mile I-78 WB is briefly 65 before being reduced to a speed limit of 5 because of the toll after the bridge. I may be wrong though.
I-78 is normally 65 right thru the state line between PA & NJ, although construction had the limit temporarily down to 50 in NJ. At the toll plaza, the express EZ Pass should be supporting 65 thru the lanes. Amazingly, GSV hasn't been updated since 2008 near the toll plaza.
I shouldn't be quoting an old post, but I refer to the cash lanes.
I don't like bumping such an old thread, but it looks like ND 200 drops from 65 to 30 once crossing into Minnesota.

I'm seeing a drop from 65
to 55 (https://goo.gl/maps/sAGiYoGLfJLsgVAR9) in GSV.

Oops must have missed that sign. It drops to 30 very soon after that.
NY/MA 23: 55 in NY, 30 in MA.

Where it enters the town of Halstad. Typical speed limit drop when entering a town, nothing to do with the state line.

I seem to recall US-15 dropping from 65 in Pennsylvania, where it's a freeway around Gettysburg, to 55 in Maryland.
The inverse happens going from Maryland (65) to PA (55) on I-70. That 55 mph stretch in PA is utterly pointless.
Since the thread was bumped, I'll note the spot mentioned above on I-70 near Hancock now goes from 70 mph in Maryland to 55 mph in Pennsylvania and vice versa.
I suspect NY has a handful of 55 2 lane roads that become 45 immediately in PA
Ones I checked and went 55>45:
NY 19 > PA 449
NY 14 > PA 14
NY 26 > PA 267
NY 79 > PA 92
Chautauqua CR 69 > PA 69
Not sure if this qualifies, but I-87/I-287/NY 17 near Suffern, NY. The Thruway mainline is (impressively) 65 MPH here. If you take Exit 15 for 287/17, you immediately cross into Mahwah, NJ where the limit drops to 55. Though if you stay on 287 south for another mile or so, it jumps back to 65.
The speed limit on US 191 north of Flaming Gorge gets a bump from 55 to 70 mph at the Wyoming state line. I want to say SR/WYO 150 to the west does the same thing.
One I totally forgot about is US 52/US 119 crossing for the final time northbound from Kentucky into West Virginia. WV's speed limit is 65, while Kentucky's is 55.
