According to local TV station KING 5:
"SEATTLE - Traffic is stopped eastbound eastbound on the Evergreen Point Floating Bridge because anti-war demonstrators have blocked traffic.
The handful of protesters managed to erect a tripod-like structure on the roadway, blocking traffic.
The Washington State Patrol has arrived on the scene and have apparently made some arrests.
Westbound traffic is also at a crawl, and traffic on Interstate 5 is also backed up."
