The Bridge On the River Trinity

Blame it on the fact that I had nothing better to do, but I was looking for something on the City of Dallas' Web site (didn't find it) and ran across a page that purports to show the construction progress on one of the Calatrava bridges across the Trinity. There are 10 pictures on this page and I could not find any difference among the 10. Perhaps better eyes than mine can spot what's going on here, but to me it looks like the City still has Col. Nicholson locked up in The Hole.
