Three Collin County roadways are on the Texas Department of Transportation's list of the 100 Most Congested Roadways, released Tuesday by the state agency.

The list provides the specific sections of roads that are most congested and explains the cost of delays both in hours spent in travel and the monetary value of lost time and fuel.  

Collin County's Most Congested Roadways

  • No. 53 – U.S. 75 (Central Expressway) from U.S. 380 to Spur 399; annual hours of delay: 327,797; annual cost of delay: $12.19 million 
  • No. 56 – U.S. 75 from State Highway (SH) 121/Sam Rayburn Tollway to SH 190/President George Bush Turnpike; annual hours of delay: 1,063,470; annual cost of delay: $36.84 million
  • No. 91 – Coit Road from West Spring Creek Parkway to Forest Lane; annual hours of delay: 358,702; annual cost of delay: annual cost of delay: $21.23 million

As part of an ongoing commitment to address congestion, TxDOT released the list of the 100 Most Congested Roadways. Topping this year’s list is a section of I-35W in Fort Worth that caused Texas motorists to spend more than 2 million more hours traveling on a section of road that is only 3.7 miles long. 

“One of the best ways to keep Texas moving is to identify those roadways causing the most delays,” Phil Wilson, TxDOT Executive Director, said in a news release. “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.”

The 100 Most Congested Roadways clearly illustrates the severity and extent of the Lone Star State’s traffic problem, according to the news release. Results show 40 percent of the delay encountered by drivers takes place in the top 20 roadways on the list. Additionally, the total delay in hours – more than 137 million hours – carries with it an economic cost in lost time and wasted fuel of nearly $3 billion.

“To truly address congestion in Texas, we must look at a variety of solutions,” Wilson said in the news release. “Most often, reducing traffic congestion is more effectively achieved by improving or constructing alternate routes, quickly clearing crashes, re-timing traffic signals, augmenting transit and implementing workforce efforts such as telecommuting and flexible work hours.”

The 100 Most Congested Roadways list is created annually with the help of the Texas A&M Transportation Institute (TTI). The methodology used to compile the list combines TxDOT’s roadway inventory and traffic volume data with speed data from INRIX, a private company that provides data to several navigation and traveler information services.

The analysis is conducted on all roads in Texas regardless of the agency that built or maintains them; city streets and non-state-operated toll roads are included in the list.

TxDOT is currently widening U.S. 75 through McKinney, and mitigation plans are being developed for Coit Road and for the section of U.S. 75 from SH 121 to SH 190, TxDOT said.
