PORTLAND, Ore. (KOIN) — KOIN 6 News has learned that at least five vehicles and a semi were involved in a crash that blocked the northbound lanes of Interstate 5 just south of downtown Portland for most of Tuesday morning.

The crash happened around 6 a.m and the freeway wasn’t completely reopened until just before Noon.

Based on a statement from a TVF&R spokseperson, a driver was headed northbound, just south of Lower Boones Ferry road, when they spun out and hit the median. A second car slammed head-on into the first car and at least three other vehicles collided with those two cars. A semi with a trailer jack-knifed to avoid the crash. The driver of the semi needed to be extricated.

In a picture from an off-duty Washington County Sheriff’s Deputy who was on the way to work when they came upon the scene, it is clear that the semi-truck is on its side, blocking several lanes.

TVF&R says there was roughly a foot of standing water on the freeway at the time of the crash that may have contributed to the incident.

There are no reports of serious injuries due to the crash.
