A traveler noticed an amusing error on a highway sign and sent a photo of it to media observer Jim Romenesko. When the people responsible for the sign were told about it, they said they would correct it but added that there was no urgency since most people would know that it was meant to read ‘mile’.
But what interested me was this bit of information that the official gave.
“It’s not safety-related, which would obviously be a higher priority,” [DOT spokesman Ryan] Viggiani said. What has probably happened is that a strip of the magnetic tape that makes up the sign lettering has fallen off, he said.
I had thought that the words on these signs were painted on but apparently it is made up of magnetic tape. But when you think about it, that makes a lot of sense because it then becomes easy to change signs. You just strip off the old tape and stick on the new and can even reuse old bits of tape. With paint, you would have to paint over the old words and paint the new, a tedious and expensive chore.
