AUSTIN (KXAN) — The area of Loop 610 between Interstate 10 and US Highway 59 in Houston was ranked first for the most congested roadway in Texas.

The Texas A&M Transportation Institue released its latest Texas’ 100 Most Congested Road Sections report Monday and found drivers were delayed 4 million hours along the stretch that passes through the Galleria area, costing almost $98 million.

A stretch of road in Dallas — Woodall Rogers Freeway, from US Highway 75 to Beckley Avenue in Dallas — came in second.

When it comes to truck traffic, the part of I-35 from U.S. Highway 290 in north Austin to Ben White Boulevard/State Highway 71 in south Austin ranks number one as the most congested section in the state, but third overall. Drivers were delayed nearly 8 million hours along that stretch of I-35.

The cost of the congestion on I-35 through Austin totals more than $200 million, Texas A&M estimated, more than twice as much as the Loop 610 in Houston, which costs nearly $98 million. The institute calculated the total cost based on the cost of fuel and delays.

This annual report helps planners with the Texas Department of Transportation focus on where to prioritize road projects.

Some construction projects on I-610 include a dedicated bus lane, direct connectors and express lanes coming soon. The city is also working on a $5 million downtown redesign study to examine corridor travel patterns within the Loop.

I-35 through Austin is expected to get an overhaul through the I-35 Capital Express Project, with construction already starting on I-35 south of Ben White to State Highway 45.
