I. Public Art Medallions. I-275 and Howard Avenue, I-4 and 22nd Street, Tampa. When the Florida Department of Transportation needed to widen the interstate highway through two of Tampa’s most historic neighborhoods, West Tampa and Ybor City, the staff knew that the residents expected them to soften the intrusion with some sensitive public art. Bill Culbertson’s scenes of neighborhood life — dancing, listening to the lector at a cigar factory, standing in front of a casita — are all mounted on a red brick interstate overpass with traditional lighting and detailing.
