Two semi-truck incidents hit the Seattle-Tacoma freeway system within hours of each other on Friday morning, October 30 — a trailer loaded with bananas caught fire on northbound Interstate 5 in Tacoma and blocked three lanes for hours, while an overturned semi shut every westbound lane of Interstate 90 in Seattle. No injuries were reported in either incident, but for the Punjabi and South Asian truckers who work this corridor daily, it was a morning of burned cargo, detours and lost hours.

What happened on I-5 in Tacoma
The fire was reported at about 6 a.m. near the north end of the Puyallup River Bridge, on the Tacoma-Fife stretch of northbound I-5 in Pierce County. According to the Washington State Patrol (WSP), the semi's trailer was carrying a load of bananas. The blaze blocked three lanes of the interstate, and photographs released by WSP Trooper Rick Johnson show the trailer burned out and torn open, with produce boxes and debris scattered across the roadway and a cleanup excavator working at the scene.
The left lane and the HOV lane stayed open while firefighters worked, but traffic backed up as far as eastbound State Route 16. WSDOT said firefighters had the fire extinguished by about 7 a.m., and the blocked lanes reopened before 8 a.m. No injuries were reported in the accounts published by Friday afternoon.
What may have caused the fire
The cause of the fire remains under investigation. Reporting based on the State Patrol's account says the truck's brakes are believed to be a possible cause — that is an early working theory, not a finished finding, and the WSP has not announced a final cause. Brake overheating is a well-known fire risk for heavy trucks, which is why troopers and inspectors treat brake condition as a core item in roadside commercial-vehicle inspections.
The second crash: semi rollover closes I-90 in Seattle
Hours earlier and about 30 miles north, an overturned semi blocked all westbound lanes of Interstate 90 in Seattle, near Rainier Avenue South and the I-5 interchange. Traffic was detoured while crews cleared the scene. No injuries were reported, and the roadway reopened to traffic at about 5:15 a.m., according to the State Patrol account reported by KORD and KIRO 7.

Taken together, the two incidents meant that both of the region's great east-west and north-south freight arteries — I-90, the transcontinental route to the Midwest, and I-5, the West Coast corridor running from the Canadian border to Mexico — were blocked at some point before most commuters had finished their first coffee.
Why this corridor matters to Punjabi truckers
The Seattle-Tacoma corridor is one of the busiest freight gateways on the US West Coast. The Port of Tacoma handles container and agricultural cargo from across the Pacific Northwest, and I-5 and I-90 carry a heavy share of it. Washington's trucking workforce includes a large Punjabi and South Asian community — owner-operators and fleet drivers based around Seattle, Tacoma, Kent, Auburn and the I-5 corridor towns — for whom a three-lane closure on a Friday morning means missed delivery windows, lost hours-of-service time and, for produce loads like Friday's bananas, a cargo claim on top of a burned trailer.
Investigators believe the Tacoma trailer fire may have started with the truck's brakes — an early theory, not a finding. Overheated brakes are one of the most common causes of truck fires, especially after long descents, and brake defects are among the most frequent violations found in roadside commercial-vehicle inspections in Washington and across the US.
A busy, disrupted Friday on Puget Sound roads
Friday was already set to be a heavy travel day in the Puget Sound region, with Halloween falling on Saturday and WSDOT warning of a busy weekend on the region's highways. The two pre-dawn and early-morning truck incidents landed on top of that demand: the I-90 rollover closed Seattle's main eastbound-westbound freeway crossing before the morning commute, and the Tacoma fire cut the main north-south route to three fewer lanes at the height of the Pierce County commute, with backups reaching SR 16.
What happens next
The State Patrol's investigation into the Tacoma fire continues, and a final cause has not been announced. Both freeways were fully reopened by mid-morning Friday — I-90 at about 5:15 a.m. and the I-5 lanes before 8 a.m. — and no injuries were reported in either incident. The burned trailer's cargo was a total loss; any insurance and cargo-claim process for the load will follow between the carrier, the shipper and their insurers.
