Interstate 35 in downtown Austin is the most gridlocked roadway in the Lone Star State for truck drivers, according to an annual report from the Texas A&M Transportation Institute (TTI).
Austin’s stretch of I-35 from U.S. 290 to Texas 71 overtook Houston’s Eastex Freeway (I-69) for the top spot, according to TTI’s annual Texas’ Most Congested Roadways report.
“Unfortunately, for drivers in central Texas, congestion on I-35 in Austin is now the worst choke point in Texas,” said Texas Transportation Commission Chairman J. Bruce Bugg in a release.
Truck drivers were delayed more than 26 million hours and wasted 44 million gallons of fuel that cost them $1.5 billion during 2019, according to the study.
In its report, released Tuesday, TTI analyzed 1,800 sections of roadway covering almost 10,000 miles in areas ranging from rural West Texas to major cities.
Though Austin’s stretch of I-35 was first on the most congested list, Houston had six in the top 10, the most of any city, while Dallas had two.
Overall, Houston had 36 out of 100 of the most congested roadways in Texas. The Dallas/Fort Worth area accounted for 33, Austin had 15 and San Antonio 11.
Laredo’s Bob Bullock Loop (also known as Loop 20) was the No. 9 most truck-congested roadway in the state. The loop is the stretch of road running from the World Trade Bridge at the U.S.-Mexico border to I-35.
In 2019, the Bob Bullock Loop was the No. 3 most truck-congested roadway in Texas.
