Yes, wasn't it so well engineered that they had to repave the connector ramps with blacktop because the concrete kept cracking - the bridges had too much flex, and not enough supports?
Have you driven on Central since they shaved about a foot or 18 inches off of each lane to make the ride more exciting north of LBJ? Of course, the stretch through the Park Cities/MStreet area still has full width lanes and a left side shoulder.
I don't know who came up with the idea of HOV lanes but they should be taken out and shot.
