PORTLAND -- A jackknifed semi at the Rose Quarter has shut down all southbound lanes of I-5.
Commuters are being diverted to I-405. ODOT said there is no estimate of when lanes would reopen.
Spokesman Don Hamilton said de-icing trucks had prepped the area overnight and did not think weather was a factor in the 4:30 a.m. crash.
The driver was taken to Legacy Emanuel. A condition report was not available.
A rollover semi crash shortly after midnight on northbound I-205 has shut down the Gladstone off-ramps, along with 82nd Drive. That closure may last through the morning.
