Longest distance on a curve advisory sign

[Kniwt]

I'll start by nominating this one, on CA 36 westbound just outside Red Bluff (even though there are many reasonably straight sections in that 140 miles).

[Roadrunner75]

I think you win.  I got nothing.

[Zeffy]

I'd be shocked to see if there is a sign with a greater distance than that.

[Rainking75]

I've never seen one even close to that...
Are there additional signs along that route? What about coming from the other end?

[Kacie Jane]

Ditto.  Highest I've seen was somewhere in the 60s (US 12 in Eastern Idaho).

There's another one with about 80 miles to go, but I didn't stop for a picture. And at the other end, I was so relieved to be done with it (I didn't know about the extended 1.5-lane segment with the blind curves and the steep dropoffs!) that I got on 101 and didn't look back.

Pennsylvania has advisory signage that reads Wear Seat Belts, Next Million Miles.

Thanks jake!

Thanks jake!

Isn't that erroneous? If that roads leads to a road that leads to a road........and so on that goes through New Hampshire then they've misled the driver.

I'd like to see that "in person". Judging by the alignment of the type, it looks like someone doctored the sign by adding a 1 before 40.

Streetview has the sign with 140, so it's not a doctored photo.

Actually it looks like the 1 & 0 were added, as "4 Miles" would be nicely centered justified.

But looking at it from an aerial view, 140 is probably legit. Advance a little and there's a sign saying the road is subject to closures 96 miles ahead!

Is the "Animals" sign on US 93 near its Southern terminus in Wickenburg AZ still up? IIRC it had a sightly longer distance: 144 miles (232 km).

There are similar signs on CASR-58 west of I-5 and several places on CASR-1, but those distances are still double digits.

Only sign there now says 37 miles (same as GMSV in 2011)...

144 miles would be well past Kingman...

These signs were installed well before Clearview negative contrast signs were disallowed.

Negative contrast Clearview was never approved.

Pertinent portions of the IA quoted below...

Purpose: The purpose of this memorandum is to issue an Interim Approval for the optional use of the Clearview font for positive contrast legends on guide signs

Research on the Clearview font: ... Both the Pennsylvania and Texas Departments of Transportation have reviewed the research on the use of Clearview font for guide signs and have requested that Clearview font be allowed to be used for positive contrast guide signs.

Conditions of Interim Approval: ... The Clearview font should not be used on negative contrast signs until research demonstrates the effectiveness. / Interim Approval for the use of Clearview font for positive contrast legend on guide signs will be granted to any jurisdiction that submits a written request to the Director of the FHWA Office of Transportation Operations. The request must state the location(s) where the devices will be used and the jurisdiction's agreement to comply with ...

PennDOT and the PTC used to be much worse with using Clearview where it wasn't approved, but their latest Clearview signs are usually 100% correct. I haven't seen any of those black-on-yellow advisory signs installed new since brief switch to Highway Gothic, though, so I don't know if they're still being made in Clearview.

Last time I drove through Pennsylvania (September 2017), I noticed that most of the Clearview 'advisory message' black on yellow signs had been removed, but not replaced with Highway Gothic ones.

Thank God you filled him in. Can't imagine how he got by without that clarification for the last five years.

My point is this:  If a sign is fabricated to a standard that is acceptable at the time of fabrication, but is later deemed to be unacceptable (for whatever reason), it doesn't qualify as a design error.

It wasn't.  Negative contrast was specifically excluded in the IA.
