Photos taken today. The new ramps use steel and concrete beams rather than the segmental precast design that was used for the original structures, visible in the third photo. Segmental is highly unsual in Texas (the High Five in Dallas is the only other use I'm aware of), and it has a look similar to California-style cast-in-place concrete. I'm thinking precast segmental is more expensive, so standard steel and concrete beams are being used.
