Highest speed zones

[roadman]

or it's just a mistake.

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

It's actually 30 mph.  From the 2009 MUTCD:

Section 2C.07 Horizontal Alignment Signs (W1-1 through W1-5, W1-11, W1-15)
Standard:
01 If Table 2C-5 indicates that a horizontal alignment sign (see Figure 2C-1) is required, recommended,
or allowed, the sign installed in advance of the curve shall be a Curve (W1-2) sign unless a different sign is
recommended or allowed by the provisions of this Section.
02 A Turn (W1-1) sign shall be used instead of a Curve sign in advance of curves that have advisory speeds
of 30 mph or less (see Figure 2C-2).

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.

I believe I saw a couple 60 mph advisory signs before a curve along I-68 in WV where the posted speed limit is 70.

Either you made a typo, or you missed the point of my post.

Well, now the question is posed, has anyone ever seen an advisory HIGHER than the posted speed limit? I can't say where, but I have - in places where a town speed limit was extended as the town grew, but the old advisory plates weren't removed from what had been a default 55 zone.

How about the State of Connecticut on off interstate routes?  Are there any local US and State routes that are non freeway with speed limits posted above 45 mph?

On US 7 you can only do 55 mph on its two freeway segments.  Most of US 7 where its two lanes is 40-45 mph and lower in villages of course.  I have not been on any other rural two lane roads in CT, but even know that most of US 1 is arterial especially from NY State to East Haven for sure. 

Are there even any rural areas in Connecticut anyway?  All along I-84 when I drove it in its entirety seemed mostly suburbia from MA to NYS.  I can see why they were very reluctant in going 65 when the 55 mph maximum was repealed.

Hit up eastern CT or the northern edge sometime. You'd be surprised. And if you take the CT 74-US 44-CT 101-RI 101-US 6 combination from Hartford to Providence, I believe CT 101 has a 50 or 55 mph speed limit.

I've driven all along the northern edge of CT and some random points all around the eastern part of the state (mostly from Manchester to RI) and have never seen a 55 zone off a freeway, but I have seen plenty of 50s.
