Lowest Posted Speed Limit on a State Highway

[sparker]

TX 165 has a speed limit of 10.

It's an official state highway, but it's a special use road, running through the state cemetery.  It's very narrow, it has gates with daily closed hours, and it's impossible to drive the length of it without backtracking.  There's no room to park along the road, and parking is provided in a lot on Navasota Street, but the gates are open, suggesting that it's legal to drive through.

https://www.google.com/maps/@30.2678573,-97.725574,3a,30y,193.39h,87.68t/data=!3m6!1e1!3m4!1sLbC_bQinGiGlC07ufTJblw!2e0!7i16384!8i8192?hl=en

Given that Texas has FM/RMs, spurs and loops that go up into the four-digit range, it's strange as hell that that warranted a three-digit primary designation.

Either "To-Market"  designation could be taken the wrong way and could be seen as encouraging body harvesting for agricultural purposes. 

Ooh -- it's just down the street from Franklin BBQ -- and it's actually signed!  Doesn't look like it connects to any other state routes either.  Next time I'm through there (with a requisite stop at Franklin!) I'll certainly be checking it out!  Weird -- but it kind of reminds me of CA 153 at the Marshall Gold Discovery park in Coloma -- but at least that one connects with CA 49! 

Since TX has differentiated all sorts of secondary routes, I suppose they could initate a "grave-to-market" series!

If I ever find myself in Austin this route will end up being featured on Gribblenation.  It certainly wouldn't be the first graveyard I've featured nor would it be the last.  I think you hit on a good title for an article; "Grave-to-Market on Texas State Route 165."

There are quite a few 25's in Michigan, such as:
US-10 in Ludington: https://www.google.com/maps/@43.9556503,-86.4435277,3a,18.4y,267.67h,87t/data=!3m6!1e1!3m4!1sv-cUoMJYw4ZqWrH83uof3g!2e0!7i16384!8i8192?hl=en
BUS US-31 in Whitehall: https://www.google.com/maps/@43.4096721,-86.3445176,3a,75y,289.79h,82.43t/data=!3m6!1e1!3m4!1sLSpZxgZBWvMdBSTKidIRgg!2e0!7i16384!8i8192?hl=en

NC 128 near the summit of Mount Mitchell has a posted limit of 10 MPH. No GSV is available of it, however, I was able to find it on video, near the end of it you'll be able to spot it, the forum removes timestamps in links.

Here in NC, a lot of towns have streets with speed limits of 20 MPH, many of which have highways routed on them. NC 207 in downtown Monroe is one example.

This is probably the lowest you'll get in the state besides the aformentioned summit.

In Arizona, SR 89A is is 20 mph through Jerome.

NYS has many, many (many) 30 MPH speed limits on state roads. Peekskill lowered their city speed limit to 25 (idk how they got away with that since the legislature has to approve area speed limits below 30). So US 6, US 202, NY 35, and a snippet of NY 9A all have 25 MPH limits. I don't really count state routes within NYC since they're owned and operated by the city DOT. That said, NY 25, NY 25A, NY 27, US 1, and US 9 all have 25 MPH segments within the city.

Outside of NYC (which got special dispensation for it's city-wide 25 mph limit), speed limits aren't supposed to be below 30 for a speed zone and 25 for a linear speed limit, with the exception of school zones.  Peekskill might have just decided to do it anyways - I saw a 15 mph limit on US 6 and US 202 just east of US 9 (outside of Peekskill, NY 27 have a 15 mph limit at its eastern end).

Then there's the Village of Colonie, which managed to de facto set its limit at 25 by posting a linear speed limit on every single road they maintain.

Mackinac Island has a speed limit of 12 mph that includes M-185

Wasn't that at 15 MPH for a long time?  I could have sworn it was in the early 2000s?

[Revive 755]

Excluding school zones, Illinois has a 20 mph section on IL 23 through Marengo.  Streetview

I think there are similar stretches through other towns.

There are a couple other cases of 25 or lower on a state highway. NY 196 in Hudson Falls is posted at 25, as is the tolled section of NY 431 and a city-maintained section of NY 32 in Albany. I've seen random 25s elsewhere, but hell if I can remember where.

A city-maintained section of US 4 in Troy is posted at 15 MPH, but as mentioned above, this is unenforceable.

[vdeane]

NY 196 is a linear speed limit, and linear limits can be 25.  The speed limit for the village overall is 30.

I can't believe I forgot about that part of US 4.  It's weird, especially since it's short and has no warning.

On the west end of Elkton, SR 38 runs through a school zone.  20 MPH when the light is flashing!  The problem is that the school runs that light longer than needed. 

No doubt some business districts have state routes going through them with 20 MPH speed limits in Oregon.  I have yet to see anything lower than that speed posted on a state route over here.  Maybe someone else has.  If so,  I would love to hear about it!

Yeah, US-20 through Sisters is the first one that comes to mind for me (20 MPH), though there are many examples (US-30 in Astoria is another). I don't think I've seen anything below 20 MPH on any publicly maintained road in Oregon (eg not parking lots and the like, also not roads in parks), let alone a state highway. Same for Idaho. Though there may be some examples of that.

Now that I think about it, I can't think of any specific examples of 20 MPH on a state highway in Idaho (plenty at 25), but I'm sure it exists somewhere (EDIT: After digging in GSV, I'm less convinced there's a 20 anywhere on an Idaho state highway. If someone can find an example, I'd like to see it. Excluding school zones).

Since ferry routes are state highways in WA and you aren't supposed to move your vehicle between the docks, then it's technically a 0 MPH zone. 

[JayhawkCO]

So just for the record, we currently have four highways with 10 mph minimums:

CO170 in Eldorado Springs
UT96 in Clear Creek
TX165 in Austin
NC128 at Mount Mitchell

No 5 mph to be had?

Forgot to mention, if it counts, the 10mph truck speed limit on a long downhill stretch (ending in a sharp right turn,) of MD 135.

The car speed limit there is 50mph.

[Verlanka]

This wins the thread.

[bugo]

US 59 in Ottawa, Kansas had a 10 MPH speed limit until about 15 or 20 years ago. The town has since been bypassed and old 59 is no longer a state highway.

[roadfro]

For Nevada, there's plenty of examples of 25mph speeds on state highways and US highways through small towns. I'm not aware of any state highway that dips below 25mph.
