Anyone know any more info on this? Fatal motorcycle crash on Viaduct By Seattle Times staff A motorcyclist died instantly this morning after losing control and colliding with a support pillar on the Alaskan Way Viaduct near Safeco Field. The viaduct's southbound lanes were expected to remain closed until 10:30 a.m. so Seattle police traffic collision investigators could analyze the scene in which debris was strewn over 300 yards, said police spokesman Sean Whitcomb. At 4:52 a.m., a passing motorist called 911 to report seeing a body in the middle of the viaduct's southbound lanes, Whitcomb said. Investigators determined the motorcyclist was traveling "at an excessive rate of speed" and somehow either fell or was thrown from the motorcycle, he said. It does not appear that any other vehicles were involved.
