On February 4th at approximately 8:56 a.m. a 39-year-old male bicyclist was travelling southbound on 24th Avenue NW approaching NW 65th Street.  At the same time a white Ford van driven by a 44-year-old female was facing southbound in the inside lane on 24th Avenue NW and was the first vehicle stopped for the red light at NW 65th Street with other vehicles behind it.   As the traffic signal turned green for southbound and northbound traffic, the van and the bicyclist proceeded forward into the 6400 block of 24th Avenue NW.   At some point in this block, the bicyclist and the van collided.  The exact circumstances that led to the collision are still under investigation.   The bicyclist was transported to Harborview Medical Center with life-threatening injuries.  Officers evaluated the driver of the van who showed no signs of being under the influence of alcohol and/or drugs.  The van driver was interviewed and released pending further investigation.  Traffic Collision Investigation Squad Detectives responded to the scene and continue to actively investigate.
