Title: Lowest posted speed limit on a rural US highway
Post by: bugo on March 31, 2014, 12:57:23 AM
The speed limit on a stretch of US 259 in rural LeFlore County, Oklahoma is 25 MPH due to sharp curves.  Is there a stretch of rural US highway in the US with a lower posted speed limit?

Is that an advisory speed, or a regular speed limit? Frontage roads for US 71/165, which will become the mainline lanes once construction is complete, has an advisory of 15 MPH.

Let's just speed it up and ask has anyone seen a posted speed limit lower than 25 mph?

I believe when US 34 goes down Main Street in downtown Plattsmouth, Nebraska, the speed limit is 20 mph.  That will only hold true until they open the new US 34 bridge over the Missouri River.

I personally doubt there would be a speed limit lower than 20 mph on a US highway and it's probably routinely not below 25 mph.

I have seen some places along US 258 in NC ( I think its Rich Square) that is 20 mph.

Also US 441 in Downtown Okeechobee, FL has it ( or had it) at 20 mph.

Only way I see there being below 25, is if it is a school zone along the US route.

RURAL US highway.  Did you even read my post?  I doubt those downtown highways you are referring to are rural highways.

Sorry man, I did not read it all, but maybe should amend your header!  When you think about low speed limits you think of that.

Anyway, Connecticut has plenty of 40 mph rural roadways is the lowest I have seen.

Back in the 70's there was a stretch of US 101 in Mendocino County CA that was so narrow and curvy that it had a 10 MPH advised speed below the curve sign.  When I saw a Greyhound bus coming the other way all I could think of was "Oh sh*t!"...LOL!  Yeah, it was That Bad!

I believe there are still some advisory 15s through Richardson Grove.  the actual speed limit is, IIRC, 30.

Around the Midwest, I haven't seen much lower than 40 mph for a rural US highway.  Urban or in-town ones, yes, I've seen as low as 25 mph with school limits of 15 mph, but nothing that low in rural areas.

Now, for a rural speed limit on a non-US highway, the Hana Highway on Maui has 15 mph in some sections.

I didn't even read the title.  Exit 11 on the NJ Turnpike probably has the most toll lanes.

How so?  Jeremy said "US highway", not "state highway", and certainly not "interstate highway".  That means the ones with the federal-type shield (not to be called "federal highway" unless you're into kinky things like viatology).

Well, I don't want to name names. So I didn't want to specify any two letters or the like.

I apologize for missing the rural in the original post.  OTOH, it wasn't in the title.  I honestly don't know anywhere rural where it is below 55 unless it's approaching (or leaving) town, a stop sign, or an interchange.  But then again, that's the Midwest for you.

The definition of "rural" could probably be debated. There are lots of places where speed limits dip to 45 or 35 for what I would consider to be a wide spot in the road, with maybe a few houses or businesses. They may or may not be incorporated places, but I'd consider them "rural."

For instance, Ezel, Ky. It's just a small community, not an incorporated town or city, on US 460 in Morgan County. The speed limit is 45 mph. I'd consider it "rural" for purposes of discussion in this thread.

This section of US 259 is as rural as it gets.  It crosses a tall mountain, and is out in the middle of nowhere miles from any towns.  There are no houses anywhere in the area.

US 13 dips to 35 mph one or twice thru the small towns in Delaware.  So while the general area is fairly rural (becoming more suburban) in nature, the 35 mph limits are located in the more populated/commercial districts.

Sounds like Oklahoma has done by regulation what most states would do with advisories.

I think there's a phrase for that:

I figured the answer had to be in Massachusetts because they love to place very low speed limit signs before intersections, rotaries, etc.

US 6 West approaching the Bourne Rotary, there is a speed limit 20 sign, on what is definitely not the middle of a city or anything majorly built up yet.  Also considering the speed limit had been 50 mph prior to that point.

That looks pretty built up to me.  The US 259 example is way out in the middle of nowhere, with nothing but rocks and trees for miles and miles as it crosses the Kiamichi Mountains.
