The Washington State Department of Transportation's Boeing Access Road South camera shows that the semi tanker is positioned horizontally across the freeway.

The Washington State Patrol says the semi tanker involved in the crash is empty.

The state patrol said the crash, which happened at about 10 a.m. Tuesday, was caused by a vehicle that was driving on the shoulder that struck an impact attenuator, causing it to spin out in front of the semi tanker. An impact attenuator is part of the barrier that is designed to absorb the impact of a crash to help reduce injuries.

Traffic is getting by in two right lanes. Initially, four lanes were blocked.

Shortly before noon, a trooper tweeted that a class C tow truck was on the way to remove the semi tanker.

Metro Transit says riders should expect possible service delays on Route 101.  As of 11 a.m., there was about a 2-mile backup on both directions of I-5.
