A two-vehicle crash involving a semitruck on northbound I-5 near the I-405 split in Portland caused heavy traffic on Monday morning. Oregon Department of Transportation said one truck was carrying chickens, but it is unknown if any were hurt, as per KGW.

The Oregon Department of Transportation said that multiple lanes on I-5 were closed after a crash, leaving only the far left lane open. The Marquam Bridge, I-405, and Naito Parkway exit remain accessible, according to Mike Warner of KATU. No injuries were reported.

Oregon Department of Transportation says cleanup from a crash on northbound I-5 may cause lane closures between the SW Macadam off-ramp and the I-405 interchange/Marquam Bridge, as reported by KPTV. The cause of the crash is under investigation. Drivers are advised to use alternative routes and allow extra travel time.
