Motorcycle collision on Viaduct, life-threatening injuries

On April 1st, at approximately 10:15 pm, West Precinct officers responded to a report of a motorcyle collision in the southbound lanes of the Alaskan Way Viaduct, at approximately South King Street.  When officers arrived, Seattle Fire Department was already on scene tending to the motorcyclist, a 48 year old female.  The victim was transported to Harborview Medical Center with life-threatening injuries.

The initial investigation indicates that the rider likely lost control of the motorcycle at the south end of the viaduct, where the roadway veers to the left before heading down toward the stadiums.  It appears that the rider failed to negotiate a curve and collided with a concrete barrier, ejecting the rider. It is believed that only the motorcyle was involved in the collision, and that no other vehicles were involved.

Detectives from the Traffic Collision Investigation Squad (TCIS) responded to the scene and began their investigation.  The roadway was closed for several hours while the detectives conducted their investigation.  TCIS will continue to handle this investigation.
