Yeah, the protected path is on the Gulf of America side. South, there's a big curved ramp that comes up out of D/T. North, the path seems to go down and end @ a crosswalk? And then you get over to surface streets...somehow. I haven't seen an aerial view or map yet, but hey, TXDoT has been working on this for a decade, so I'm sure it's great.
Next up, the Beltway 8 Bridge over the Houston Ship Channel.
