Tacoma has WA’s deadliest 10-mile stretch of highway, report says. Where is it?
The Tacoma area has the deadliest 10-mile stretch of highway in Washington, according to a new report.
The section of Interstate 5 between South 38th Street and State Route 18 saw 22 fatal crashes between 2019 and 2023, according to an analysis published by Seattle Injury Law. Twenty-five people died in those wrecks, per the report.
Meanwhile, another stretch of I-5 in Tacoma also is considered among the deadliest statewide, along with highway sections in and near Bellingham, Everett, Olympia, Renton, Seattle, SeaTac and Vancouver, according to the report, which was published Sept. 19.
The analysis was based on data managed by the National Highway Traffic Safety Administration, per the report.
Here’s a closer look at the report, plus more state-level traffic fatality information:
How deadly is I-5? What about other Washington highways?
I-5 makes the most appearances on the list of the deadliest 10-mile stretches of highway in Washington, with all but three of the entries featuring part of the major north-south thoroughfare. I-5 runs down western Washington from the Canadian border to Oregon and beyond.
A section of Interstate 205 also makes an appearance, and so do sections of Interstate 405 and 90.
All of the highway stretches on the list are in western Washington. It wasn’t immediately clear how many highways total in the state were examined for the report, which used 2019-23 data from the Fatality Analysis Reporting System.

How many fatal wrecks are there on Washington roads every year?
Traffic fatalities dropped in Washington in 2024 for the first time in several years, according to preliminary data from the Washington Traffic Safety Commission released in May. The state saw 731 traffic deaths in 2024 compared to 809 in 2023, the agency said in a news release.
Still, that was a 36% increase over the 538 traffic deaths in 2019, per the release.
“This is obviously a welcome change to see our annual fatality numbers decline after experiencing large increases over the previous four years. Law enforcement and other traffic safety partners have worked hard to reverse the deadly trend we experienced in 2020-2023. And we still have a lot of work to do to further reduce these historically high fatality numbers,” Shelly Baldwin, commission director, said in the release.
The commission said four behaviors by drivers play a role in at least 75% of traffic deaths each year:
- Impaired driving
- Speeding
- Distracted driving
- Failing to wear a seat belt
