The High-5 interchange in Dallas and virtually all of the major interchange on the Bush tollway are proof of that.
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.
Fifty years ago, the state engineers did the work, Don’t think that it the case any more. Anyway, a smaller problem developed north of Lewisville where they were supposed to building a new bridge connecting 407 and I0-35E. They got ready to build and they discovered that the plans for the east side and the west side did not meet properly.
