[Study] The Most Dangerous Intersections in Washington
Posted in Car Accidents on December 5, 2022
Every day, hundreds of people are involved in motor vehicle collisions throughout the state of Washington. Nearly half of these collisions occur at or are related to an intersection.
At Colburn Law, we are acutely aware of the devastating toll that car accident injuries can take on victims and their families. For this reason, we set out to identify the most dangerous intersections in Washington and provide motorists with valuable information to keep themselves and their loved ones safe.
We worked with data visualization agency 1Point21 Interactive to analyze five years of Washington collision data, from 2017 – 2021. We identified 50 intersections where both a high volume of collisions and injuries occurred during those years.
Below, we list the most dangerous intersections in Washington.

What makes an intersection dangerous? A high volume of collisions and injuries.
Over 70,000 unique intersections saw at least one crash during the study period, with an average of 2.5 crashes each. Intersections among our 50 most dangerous, on the other hand, averaged 78.24 crashes each.
While it is true that many of the crossings on the list below are high-traffic volume intersections, we believe that volume contributes to the danger. It means that it is more likely that someone will be involved in a collision there.

Three of the five most dangerous intersections (and five of the top ten) were found in Kent. Below is a closer look at them and the rest of the top five.
Number 1: 116th SE and SE Kent Kangley Rd
- City: Kent
- 122 Crashes
- 53 Total Injury Crashes
- 6 Severe Injury Crashes
The most dangerous intersection in Washington can be found at 116th Avenue and Kent Kangley Road in Kent. Site of the second most intersection-related collisions, it had the most total injury crashes and the most serious injury crashes.
Number 2: 108th Ave SE and 208th St SE
- City: Kent
- 138 Crashes
- 33 Total Injury Crashes
- 1 Severe Injury Crashes
- 1 Death
With 138 crashes, this crossing had the most collisions of any intersection in Washington. While fatalities are relatively rare at intersection-related collisions overall, 108th and 208th was the only one in the top five to see a fatal crash (among only five intersections in the top 50).
Number 3: 112th SW and Evergreen Way
- City: Everett
- 92 Crashes
- 36 Total Injury Crashes
