From The Austin Monitor:
New figures released by the Texas Department of Transportation quantify what anyone who drives in the Austin area instinctively knows – traffic congestion on several local roads and highways is as bad as anywhere in the state and getting worse.
One stretch, Interstate 35 through downtown between the U.S. 290 intersection and Lady Bird Lake, ranks as the second-most congested roadway segment in the entire state, and ranks first in freight-related congestion. Ten other Austin-area roadways are among the worst 100 in the state.
TxDOT recently released the 2014 Most Congested Roadways in Texas, with numbers updated from 2013. The data comes from the Texas A&M Transportation Institute, which uses roadway inventory and traffic volume information from TxDOT along with speed data from INRIX, a private-sector source of traffic data. The complete list is available on the TxDOT website.
