Highest speed zones

The speed limit on the Muskogee Turnpike is 75.  Through Muskogee, where the turnpike is discontinuous but connected by OK 165, the speed limit drops to 70.  Are there any higher speed zones?  I imagine Lawton is the same way.

I've not driven it, but there is at least one toll road in Texas with a posted limit of 85 MPH.

Same for I-49, the speed limit is 75 from Alexandria to US 167, but drops to 70 in Opelousas.

Highest I've ever seen (that I can remember anyway...) is 70 on I-95 somewhere between DC and Richmond, I think. Somewhere down there above Richmond, anyway. :P

Am I correct reading that the question is about the highest speed zones, not just highest speeds?  That is, highest reduced speeds?

The oddest one that comes to my mind (which still isn't all that odd probably) is I-65 near Lafayette, IN where it drops from otherwise 70 mph to 65 mph.  Probably it has to do with congestion/amount of traffic; the road itself isn't significantly different in quality from the long 70 mph stretches on either side.

Nevada has a "speed zone 70" somewhere on I-80 as you approach Reno from the east.  75, 70, then 65. 

on a related note, the highest curve advisory I've seen is 70 on I-70 in Utah.  I believe one Oklahoma toll road (Will Rogers?) has 75mph advisory for the electronic toll collection.

This isn't the highest advisory speed I've seen (I've seen 65 somewhere, probably Montana, and certainly believe higher exists), but certainly the most amusing advisory speed I've seen is a 60 MPH curve on I-5 in the southern part of this county, squarely in a 60 MPH regulatory zone.

Yes.  "Speed zones" as in "speed zone ahead."  Not "speed limits."

It's about the speed zones that are highest. Not the speed zones with the highest speeds. Yeti crossing, anyone?

That's what I thought, but it took a turn at the 85mph item and I was afraid it was going the wrong way.  ;)

The term "speed zone" seems to vary in frequency of usage from area to area.  I don't remember seeing it when growing up in Mass, but other places were chock full of Speed Zone Ahead signs.  Lately the term is making a comeback with standard worded "XX MPH Speed Zone Ahead" signs in the MUTCD.

there is a road around here with a speed limit of 35 and a curve advisory of 40. 

I believe it is a case of a missing "speed limit 45" sign, as eastbound one sees "speed limit 35", "advisory 40", "speed limit 45" in that order, while westbound the signage is "speed limit 45", "advisory 40", and then "speed limit 35".

I tend to do ~38-39 on that section of road and am generally surprised when the speed limit increases to 45, as the superelevations and sight lines do not generally support it in my opinion.  it is low traffic but a tricky road to drive.

I have seen a 70-mph advisory curve on I-17 in Arizona near Sedona, through one of the mountain grade areas.

MUTCD allows posting advisories as the same speed as the limit. In other words, it's acknowledging driver behavior: "Yeah, you who's going 20 mph over, you actually do need to slow down here." A couple of 55 and 60 MPH advisories popped up in NJ when we went to 65 mph - I-280 leaving I-80 (60), and NJ 24 at Exit 7 (I think 55, could be 60). Still no 60 MPH limits here though, but that's a different topic.

Does anyone know where exactly you can find a 75mph advisory sign? I've seen a picture of it but I can't find it anywhere on street view

I just do not remember where the mainline collection points are unless I zoom in a lot on an aerial, and right now I am too lazy to go down the road in 500-foot segments  :sombrero:

Well since I'm currently being impacted by Hurricane Sandy and I have nothing else to do, I decided to do that :D because of street view though and its random segments of non coverage, this is really the closest I could get to seeing a 75mph sign http://goo.gl/maps/pmVTN

The High Plains Traveler

There is at least one 70 mph advisory speed in a 75 zone on I-25 in Colorado (near Colorado City as you go over the toe of the Wet Mountains south of Pueblo). I have never seen an advisory speed equal to the speed limit here. Colorado typically posts speed limits in the mountains lower than the prevailing speed limit (65 on 2-lane roads) that reduce the requirement to post advisory speeds.

Not a "speed zone" per se, as Nevada doesn't sign anything as such, at least not with typical "speed zone" signage...

The speed limit east of Fernley is 75 -- NDOT standard for rural interstates.
The speed limit between Fernley and Reno-Sparks (roughly 25 miles) is 70, due to curvier terrain
The speed limit in Reno-Sparks is 65 -- NDOT standard for urban interstates.

There is one on southbound I-15 going into Cedar City UT at the end of the Speed Limit Test Area from Cedar City to UT 20. This was the first 80 mph Speed Limit I had ever seen. It was dark when we drove it last week. We got a photo of a Speed Limit 80 sign, but not one of the 75 mph Speed Zone sign.

is that a speed zone, or an advisory?  looks like the thread has gotten to discussing both types of signs.

That's interesting to know.  Thank you.

I've always taken a curve sign with no advisory speed to mean 'advisory speed equal to or greater than speed limit', so I always make sure to take the curve at or near the speed limit.  I had no reason other than my imagination for my interpretation.

Here's a subtopic:  What's the highest advisory speed you've seen posted with an elbow curve warning sign?

I believe there is 40 in the Sierras on one of the state highways.  it's a section with speed limit 55, where you're used to going 50-60 as it isn't particularly curvy, so they emphasize that there is, indeed, a curve coming up by using the elbow.

or it's just a mistake.  it's California.

What, exactly, is the cutoff?  I can't remember.  Somewhere between 15 and 25 as I recall...
