Read Between the Signs in Meadville, PA

I was driving back from north eastern Ohio a few weekends ago, and, as I often do, I decided to skip a section of the interstate and take a back road.  I'm glad I did, because I stumbled across this very cool public art project called, "Read Between the Signs", that was apparently a joint effort of Allegheny College and the Pennsylvania Department of Transportation, using old signs to create art.

More photos here, and below is a map of the location (as of this writing street view is broken in that area).  The searchable address is PennDOT District 1-1 Office, 18492 Smock Highway Meadville, PA 16335
