10 US cities with the worst traffic jams
Average commute during worst driving hours: 33 percent longer on Friday at 5:15 p.m.
This other Texas city isn't as congested as Dallas, but it makes the cut due to trips like the commute on US-59 between Buffalo Speedway and I-45. This 4.8-mile stretch or road, which usually takes five minutes to complete with no traffic, can take up to 14 minutes during rush hour and 24 minutes on Friday afternoon.
