Well, it depends on which big cities.
The East Texas set of DFW / SA / Austin / Houston is mostly connected by highways that stay busy. 45 between Houston and DFW is thinner, but I-10 is almost urban levels of busy from the Louisiana state line until you get well past San Antonio.
West of San Antonio or DFW? Oh yeah, it gets thin FAST.
