Yeah, in cities the bigger issue is usually that highways are terrible uses of potentially very valuable urban land, cut up neighborhoods, and so on.
The above problems can be mitigated. In Denver, I-25 runs roughly along the valley of the S. Platte River (you may have heard the name, "Valley Highway" from some old timers out there), which forms a natural division between the east side and the west side of Denver. Apparently when I-70 was built, some neighborhoods were split up, though.

Will it keep us back from every booming like a huge Texas city? Yes of course.
Actually the entire Western PA/Eastern OH area is blanketed with a spider-web of highways that would make any Texan jealous. It creates these huge loops on maps that are just begging to be developed - a loop around Beaver County; Lawrence County split into two loops; a loop on the outside perimeter of Allegheny County; a loop around Mahoning County; a loop around Trumbull County; and a loop around Pymatuning Reservoir. But not many developers have noticed it yet. Except in Cranberry and Grove City.
