Seattle, WA (September 4, 2025) – A two-vehicle crash on eastbound State Route 520 near the I-5 interchange resulted in injuries Tuesday morning and temporarily affected traffic flow through one of Seattle’s busiest highway corridors.
According to dispatch audio from the Washington State Patrol, the crash occurred shortly before 11:50 a.m. near E Roanoke St and 22nd Ave E. A gray Nissan Sentra and a box truck were involved in the collision, which prompted a swift response from emergency personnel. Officials confirmed that injuries were sustained in the crash, though the total number of people hurt and the severity of those injuries have not been disclosed.
The involved vehicles were moved to the shoulder and later cleared to a Gore Point near the I-5 connection to ease congestion and allow traffic to resume. EMS crews were observed evaluating at least one patient, and the scene was declared cleared shortly afterward, restoring the full flow of traffic on SR 520.
No additional details have been released regarding the identities of those involved or the specific cause of the collision. An investigation into the incident is ongoing.
We hope those injured in this crash make a full and quick recovery.
Highway Collisions in Seattle
Tuesday’s crash on SR 520 near the I-5 interchange reflects a recurring challenge for drivers navigating Seattle’s complex highway system. The convergence of SR 520 and I-5 is a high-density traffic area that often sees congestion, merging conflicts, and frequent lane changes — all of which contribute to a heightened risk of collisions.
The involvement of a box truck in this crash adds another layer of concern. Collisions between passenger vehicles and commercial trucks tend to result in more severe injuries due to the size and weight differences. In this case, a gray Nissan Sentra shared the impact, and emergency responders acted quickly to address injuries and minimize traffic disruption.
While the roadway was cleared relatively quickly, the presence of injuries underscores the importance of caution on interchanges and split points — especially during mid-morning travel when commuter flow remains steady. Drivers approaching merge zones or exit ramps should always reduce speed, maintain space, and avoid abrupt lane shifts.
For those involved in highway crashes, especially those that involve commercial vehicles, recovery is often more than physical. Victims may face extensive medical treatment, time off work, and the stress of insurance negotiations. Knowing your rights and how to access support systems is vital to recovering fully from an incident like this.
