The Via Transit folks have found an ingenious way of making sure you can find their downtown Centro Plaza bus terminal. It's called the Centro Chroma Tower and Public Artist Bill FitzGibbons designed it.
"It's 85 feet tall. And it's illuminated at night with a computerized L-E-D light system, which allows you to see the structure both from I-10 and even from downtown buildings."
The 10-foot wide tower on Frio, between Travis and Houston Streets has a sophisticated lighting scheme.
