Houston drivers paid nearly $1 billion in tolls — so why are they still stuck in traffic?

Houston drivers dropped nearly $1 BILLION on Harris County Toll Roads last year… and people still feel trapped in traffic. Side streets moving faster than toll lanes? That’s the kind of frustration drivers keep talking about. Now Investigator Mario Diaz is asking the tough questions — his way. Where’s the money going? Why can’t drivers clearly track it? And why are Houstonians paying more… for the same gridlock? No spin. No sugarcoating. Just answers Houston drivers deserve. Would you keep paying tolls if traffic never improves?
