Three Katy-area highways are among the most-congested roadways in the Lone Star State, according to the latest annual report from the Texas A&M Transportation Institute. I-10 between the Grand Parkway and North Eldridge Parkway is the 37th-most congested roadway in Texas with 323,711 hours wasted annually in traffic per mile—which is calculated as the extra travel time above normal road conditions multiplied by the number of people encountering it and then divided by the roadway segment length—per the report. Those hours on I-10 are estimated to cost drivers more than $63 million annually in wasted time and fuel. Nearly 195,000 vehicles drive the segment daily. Meanwhile, Hwy. 6 from I-10 to the Westpark Tollway is No. 56 on the list with 251,940 hours wasted annually in traffic per mile, costing drivers about $25.2 million annually North Fry Road also made the list at No. 98. From FM 529 to I-10, drivers waste 180,941 hours annually per mile, which is a $23.7 million annual cost. Texas A&M studied the traffic volume and speed data of about 1,800 road segments across Texas, according to an Oct. 22 press release. The Transportation Institute published a list of the top 100 congested roads, of which 39 were in the Greater Houston region. Houston is also home to the two most-congested roadways in the state: Loop 610 from I-10 to Hwy. 69, and Hwy. 69 from Loop 610 to SH 288. The Loop 610 segment has 1.7 million annual hours of delay per mile and an annual congestion cost of $119.4 million. The Hwy. 59 segment has 1.3 million annual hours of delay per mile, costing drivers $146.5 million annually Overall, traffic is worsening in Texas, the release noted. Thanks to Texas’ thriving economy, the release stated, population growth is outpacing roadway capacity.
