Most Dangerous Highways in Texas
The Texas Department of Transportation (TxDOT) maintains more than 79,000 miles of roadway – significantly more than any other state. That means there are plenty of places for traffic collisions to occur throughout the state. In fact, as much as 10 percent of all U.S. fatal car accidents happen on Texas roads.
Research has revealed that certain specific stretches of Texas highway tend to be more hazardous than others. According to Texas Monthly and the TxDOT, the top 5 most dangerous roads in Texas include:
Interstate 45 in Harris County
- I-45 connects Galveston to Houston and also extends up north to Dallas.
- I-45 is considered one of the Top 10 deadliest roads in America despite being relatively short.
- An average of 56.5 fatal accidents occurred every 100 miles of I-45 over eight years.
- An 11-mile stretch of I-45 near Houston saw 50 fatalities in 46 crashes.
- Harris County is home to the most dangerous segment of I-45, with 115 traffic fatalities in one year.
- I-45 has a negative reputation associated with the many drunk driving incidents that occur on the highway.

Interstate 10 in Harris County
- Also known as the “Katy Freeway” in Harris County, I-10 stretches across the nation from Florida to California. In Texas, it runs from the Louisiana border to New Mexico.
- I-10 passes through some of the largest and most densely populated cities in Texas, including Beaumont, Houston, San Antonio and El Paso.
- There were 246 crashes and 283 fatalities on the Harris County stretch of I-10 from 1994 through 2008.
Interstate 35 East through Dallas
- I-35 is a major north-south corridor that extends more than 400 miles from Texas’ southern border with Mexico all the way north to Oklahoma.
- The road passes through congested areas in San Antonio, Austin, and Dallas, where construction projects are common hazards.
- I-35 is an important thoroughfare for goods transported in and out of Mexico.
- More than 290 fatalities happened along I-35 within five years.
Texas State Highway Loop 1604
- TX Loop 1604, also known as the Charles W. Anderson Loop, encircles the city of San Antonio in central Texas.
- The loop extends for nearly 100 miles and frequently sees upgrades and construction projects that increase congestion.
- There are, on average, more than 200 crashes on this highway each year.
- Anecdotal evidence suggests that many accidents occur at the end of the expressway, where a stoplight catches many drivers unaware.
- I-410, also known as the Connally Loop or Loop 410, encircles San Antonio and also connects I-10 to I-35.
- The upper half of I-410 passes through several dense urban areas in northern San Antonio, with some segments having as many as five lanes to accommodate congestion.
- However, the lower half of I-410 is relatively undeveloped and passes through several rural areas in southern San Antonio as a two-lane road.
- Along this loop, there are typically more than 200 crashes in a given year.
