(April 2000) Somerset, KY. Most Kentucky interstate shields do not contain the state name. There are a few fairly new-looking exceptions though. Hopefully, Kentucky is following the course of Maryland and Colorado and reviving the state name on their signs!
No, this sign isn't missing its black paint. This sign is coated with crushed glass beads as an early form of reflectorization. Notice that both the background and the numbers reflect when a photo is taken using a flash. (Collection of Robert Edgar)
(April 2000) Lincoln Co, KY. Kentucky has about 2500 signed state routes, so most signs are 3 and 4 digits. These signs use the square 24" blank. Most 3 and 4 digit signs use the extended 36" blank.
Unlike other states which converted to a circle sign in the 70's under AASHTO pressure, Kentucky has used a circle from the beginning. This cutout sign immediately preceded the sign above and was probably used in the 60's and early 70's. (Owner unknown)
Another cut-out circle. This sign uses the older block fonts and is again from the 1960's. Notice the difference between the two K's at the top of the sign. Older signs were embossed and used only the "KY" logo at the top. (Photo by Joe Koehler)
