10 Most Dangerous DFW Highways

Car crashes are part of the background of life in a big car-dependent city. The really awful ones maybe you'll catch on the news. Others you gawk at as you drive by, or else rage at from a line of traffic. Sometimes they come and go like phantoms, vanishing by the time you arrive, with only a half-hour of gridlock to prove their existence. From the driver's seat, it's impossible to divine any pattern. It all seems very stupid and random, and to a certain degree it is. And yet, car for car and mile for mile, some roads reliably prove to be more dangerous than others.

To figure out which highways in North Texas are the most dangerous, we obtained crash data (i.e. the number of accidents) from the Texas Department of Transportation for two dozen North Texas highway segments that a 2012 analysis by the North Central Texas Council of Governments identified as having the highest frequency of crashes. Using NCTCOG's 2014 estimate for the number of vehicle miles traveled on each segment, we determined the number of car crashes per 100 million VMT. So even though Central Expressway between LBJ Freeway and Interstate 30 averaged more than three wrecks a day, twice as many as any of the others in the top 10, more cars on Central were driving more miles in 2014 than on, say, Woodall Rodgers. There are other ways to define "danger." Counting traffic injuries or deaths rather than just crashes (which the state counts if they either cause injury or look like they caused $1,000-plus worth of damage) would be another. but those are comparatively rare and subject to bigger swings from year-to-year. 

All of these roads are congested, but there's not a direct relationship between congestion and danger. If there's a takeaway here, it's that cars are dangerous. If there's a second takeaway, it's that someone should probably figure out how to make these particular highways safer. If there's a third takeaway, it's that the prevalence on this list of Tarrant County highways is is yet another piece of evidence that Dallas > Fort Worth.
