The Texas Department of Transportation has released its annual list of the 100 most congested highways in the state. The list is created annually with the help of Texas A&M Transportation Institute.
According to a press release, Texas motorists spend 137 million hours on congested roads. Texas’ number one most congested highway is a 3.7 mile stretch of Interstate 35 in Ft. Worth. According to the study, 2 million hours were spent traveling the short stretch of highway.
Forty percent of the 137 million hours delays encountered by commuters took place on 20 of the top most congested roads named. According to the study, the delays have an economic impact of $3 billion in wasted time and fuel.
“One of the best ways to keep Texas moving is to identify those roadways causing the most delays,” said Phil Wilson, TxDOT Executive Director. “Results from this annual study validate our approach to moving aggressively with our priority projects in Texas to address congestion and help Texans get to and from work and help them easily and safely move around our great state.”
