TxDOT Lists 100 Most Congested Roadways

LBJ Freeway and Woodall Rodgers Freeway in Dallas are two of the most traffic-clogged highways (shocking, we know) in the Lone Star state.

An updated list of Texas’ 100 most congested roadways was posted online Wednesday by the Texas Department of Transportation.

The report was mandated last year by the Texas Legislature, which required TxDOT to post an updated list each year by Sept. 1.

The list, (you can see the list here, and download the data supporting it) shows traffic creeps to a crawl the most in Texas’ biggest cities like H-town and the Big D.

LBJ came in third and Woodall Rogers placed fifth on the list. Additionally, two highways in Tarrant County are listed in the top twenty.

Interstate 35W from Interstate 30 to SH 183 is listed as the eighth most gridlocked road and Interstate 820 from I-35W to SH 183 is fourteenth.

Instead of relying on TxDOT traffic volumes alone, this list of congested roads relies on speed data gathered in real time by a commercial data service called INRIX. That firm has agreements with major fleets that use GPS-enabled devices to report speeds in real time. In addition, some drivers with smart phones also allow real time tracking of their speeds.
