Anti-war protesters blocked lanes on State Route 520 in Seattle during the morning commute Tuesday. State troopers arrested several people and have cleared the scene.

Protesters set up a pyramid structure with three poles in the eastbound lanes of 520 at Montlake and appeared to be trying to put up a banner on the structure before it was taken down by troopers.

Troopers made eight arrests, KIRO 7 Eyewitness News reported.

Officers removed the pole-structure, banner and towed away a car to get traffic moving again.

The incident slowed the flow of traffic across the Highway 520 floating bridge during the latter part of the morning commute, on the day following a three-day weekend for many workers.

A group of three or four dozen other demonstrators watched the demonstration and shouted anti-war slogans.

What isn't mentioned is that that traffic backup led to an accident that killed a 30 year old mother trying to get to work. When informed of the death one of the protestors said "sometimes, people have to die for a cause. This death could prevent hundreds and thousands more."
