Longest "Continuously Posted" Distance Sign

[minneha]

I was thinking more in terms of the definition in this thread of continuously signed, where it's defined as a stretch of highway where more than 36 percent of the mileage signs use a specific control city. If you use the Salt Lake City 510 sign near Baker as the starting point, it's almost certain that more than 36 percent of the mileage signs on I-15 from that point until Salt Lake City use Salt Lake City as the control city, even if there are a few signs between Baker and Las Vegas that use Las Vegas.

There are a lot of next-three-exits mileage signs in Las Vegas. (And in fact, the Jean and Sloan ones basically function as those too, since there are no exits between Primm and Jean and Jean and Sloan.) So if you count those (and I would argue you should, since places that have next-three-exit menu signs usually don't have city-distance signs posted alongside them) it would probably drive the percentage into the ground.

That might be true in terms of the total number of signs. I don't know how many mileage signs there are on I-15 in rural Utah.
