Retaining wall, fire truck damaged in collisions on viaduct

On November 7th at approximately 1:17 a.m. officers responded to a one-vehicle collision on the Alaskan Way Viaduct.  Preliminary investigation indicates that a female driver was traveling southbound on the viaduct at a high rate of speed.  Near South Washington Street she lost control of her Ford Expedition and collided into the retaining wall.  A piece of the concrete retaining wall was dislodged as a result of the collision and fell to the ground below (Alaskan Way South), damaging two unoccupied parked cars.  Nobody was injured from the falling concrete debris.

The driver of the  Ford Expedition was not injured in the collision however, her female front seat passenger sustained non-life-threatening injuries and was subsequently transported to an area hospital for treatment.  Alcohol does not appear to be a factor in this collision.

While SFD units were on scene assisting the injured passenger their fire truck was rear-ended.  

At approximately 1:38 a.m. a 30-year-old female driver and her female front seat passenger were traveling southbound on the viaduct in a Nissan Maxima.  The Nissan driver collided into the rear end of an unoccupied fire truck that was parked at the scene of the first collision.  Nobody was injured as a result of the second collision.

The driver of the Nissan was taken into custody and is currently being investigated for suspicion of driving under the influence of alcohol and/or drugs. 

SDOT is on scene repairing the damaged retaining wall.  The viaduct is currently closed to all southbound traffic but is expected to be open by approximately 3:00 a.m.

There have been no citations issued on either collision as they are both still under active investigation.
