PORTLAND, Ore. -- As the holiday traffic ramped up Wednesday afternoon, crashes were slowing traffic on Interstate 5 near the I-405 interchange, on I-405 near the Highway 26 exit, and on I-5 one mile south of Wilsonville.

A crash in Boring involved several vehicles and blocked Highway 26 for more than an hour.

Police and fire crews were called just before 3 p.m. to the report of a multiple-vehicle crash on 26, near Highway 212 (pictured, above).

The crash initially blocked all lanes, but by 4 p.m. one eastbound lane was open. Police did not release any information on injuries.
