I pass over the Fred Hartman Bridge between La Porte and Baytown, Texas (Houston area) almost every day and it is one of the most impressive bridges that almost no one knows about.

If not for all of the plants/refineries that dominate the region immediately surrounding it, the view from it would look something like the Golden Gate of San Francisco, with the San Jacinto Monument plopped in the middle of it (and given the amount of plant facilities in the region, the SJM definitely looks out of place). If built in nearby Kemah or in place of the Galveston Causeway, I think it'd get a lot more run nationally.
