PORTLAND, Ore. — Northbound lanes of Interstate 5 near the I-405 split reopened Monday after a semitruck crash caused extensive traffic delays lasting nearly eight hours. The collision involved two semitrucks, according to a spokesperson for the Oregon Department of Transportation (ODOT).
The crash occurred around 7:30 a.m., though the exact cause remains unclear. One of the trucks was reportedly carrying a load of chickens, but it is unknown if any animals were harmed during the incident. The impact left one truck cab heavily damaged and its contents spilled across the highway, as shown by traffic cameras.
The crash forced the closure of two northbound lanes, creating a traffic backup estimated at five miles. The jam extended through much of Portland, causing delays for morning commuters and complicating travel in the area. KGW traffic reporter Chris McGinness noted that the backup persisted throughout most of the day while crews worked to clear the wreckage.

ODOT continues to investigate the cause of the crash and has not reported any injuries. The incident highlights the potential hazards posed by large vehicle collisions on heavily trafficked sections of Portland’s interstate system.
Drivers are reminded to exercise caution near accident sites, follow posted detours, and allow extra travel time during major highway incidents.
