I've been documenting some of them in my [link|http://spiceware.org/gallery/ArtisticOverpass|Artistic Overpass] gallery, such as [link|http://spiceware.org/gallery/SanAntonio/dcp_0241|this new ramp] at one of the stacks in San Antonio. I need to get back down to Corpus Christi, one new section has sea animals in all the support columns, similiar to this [link|http://spiceware.org/gallery/CorpusChristi/dcp_0066|retaining wall] in Portland(just north of Corpus).
