In North Richland Hills, Texas you may notice these traffic signal boxes on Rufe Snow and on Davis. The Cowgirl has been there for a while but the one on the left is rather new. It shows several bakeries and cafe types of houses. I do not know who is in charge of the painting of these boxes but I think it is a great idea. I know these boxes have to be at each traffic light but there is no reason for them to be the usual ugly gray.
Across Texas you can find city and towns starting to think about the decorative tourist angle. In Midland, Texas when you go through and underpass you'll notice the column towers holding up the bridge itself are painted like oil cores because the city is known for the oil industry and the oil Museum. In Odessa, Texas when they built an overpass withing the last 5 years they used decorative tiles on the sides of the over pass where they build up the dirt before the bridge itself was laid across to hold in the dirt. The tiles depict a desert plant series.
All over Texas I have noticed more highway art appearing in different places you wouldn't suspect. In Dallas, Texas on the High 5 which is what they call the series of bridges criss-crossing the I75 and I635 interchange there are the lone star of Texas with a blue circle around it. I hope all this art is a continuing trend of the future.
