No injuries reported as street sweeper burns on I-405 barrier near Bothell

No injuries were reported after a collision left a street sweeper burning on a concrete highway barrier near Bothell overnight Wednesday into Thursday. The truck’s front wheels extended over the divider as flames engulfed it. Several southbound lanes of Interstate 405 closed for a few hours, but every lane has since reopened.⁠¹

The other driver was arrested on suspicion of driving under the influence, according to the Washington State Patrol’s account reported by KOMO. Troopers said that driver struck the sweeper. The arrest remains an allegation: the available reporting does not establish proven impairment, filed charges or a conviction.⁠¹

The collision happened near Northeast 195th Street in the Bothell area. The Washington State Department of Transportation first reported it shortly before midnight Wednesday, November 4. That gives an approximate point when the incident became public, not an exact time for the impact itself. The closures continued into Thursday, November 5.⁠¹

KOMO described transportation-department camera footage showing the sweeper perched atop a Jersey barrier—the concrete divider along the roadway. Its front wheels had gone over the barrier before the truck stopped. The image establishes the vehicle’s precarious resting position; the State Patrol’s account supplies the reported involvement of the other driver.⁠¹

Firefighters arrived minutes later and attacked the burning truck with water, according to KOMO’s description of the response. Heavy smoke rose as they worked. The report does not identify the responding fire departments or give a precise time when the fire was extinguished, so the sequence is clearer than the minute-by-minute timing.⁠¹

Transportation crews then cleared the scene while several southbound lanes remained closed. The disruption was measured in hours rather than a prolonged shutdown, but it affected overnight traffic through that stretch of I-405. The available account does not specify exactly how many lanes were closed or when each restriction began and ended.⁠¹

For drivers checking whether the crash still blocks their route, the answer is straightforward: all lanes have reopened. A precise reopening time is not established in the verified account. There is no need to treat the earlier images of a burning truck as evidence of a continuing traffic closure.⁠¹

The absence of reported injuries is the most consequential outcome of a scene that otherwise looked severe. It should also be stated narrowly. The report does not describe how the sweeper’s operator got clear of the fire, and it provides no basis for reconstructing an escape or assuming how many people were nearby.⁠¹

The State Patrol’s reported account identifies a suspected impaired driver as the person who hit the sweeper. It does not, in the material available, explain what observations or testing led troopers to suspect impairment. Those missing details matter to the criminal case, even though they do not change the confirmed fact of the arrest.⁠¹

Nor does an arrest establish that prosecutors have filed a charge. The available reporting leaves that outcome unresolved. Describing the driver as arrested on suspicion of DUI preserves the distinction between what troopers suspected at the scene and what any later legal proceeding might establish. It is not a finding of guilt.

There are limits to what the highway footage establishes, too. WSDOT’s camera coverage and its crews’ cleanup role do not identify who owned the sweeper. The truck was a road-maintenance vehicle, but assigning it to the state or a contractor would go beyond the account. Its ownership is not established in KOMO’s report.⁠¹

The immediate emergency has ended: the fire response and highway clearance are over, traffic lanes are open, and no injuries were reported. What remains unresolved is the legal outcome for the arrested driver. Any charging decision would be a further development—not something that can be inferred from the flames, the collision or the arrest alone.⁠¹
