Trooper Sean O’Connell was directing traffic around the collapsed I-5 bridge in Skagit County Friday when he was thrown from his motorcycle after colliding with a truck. He was rushed to Skagit Valley Hospital where he died.
The 16-year veteran is survived by his wife and two young children.
Thousands are expected to attend the memorial. Authorities expect traffic delays in the area.
The state patrol has set up a fund to support trooper O’Connell’s family. Donations can be mailed to the Washington State Patrol Memorial Foundation at P.O. Box 7544, Olympia, WA 98507.
