Some real progress is being made. The structures on LBJ at IH-35E are quite large - the aerial view really doesn't convey the magnitude. The elevated lanes along IH-35E are nearly complete.
I have tried on numerous occasions to get some ground-level photos which capture the spirit of the project, but it has proved to be futile. But I see in the video a big gaping hole in the ground at Marsh Lane, so I'll need to go there with my camera.
