11:16 PM: This is at least the fifth deadly motorbike crash in that area of 99 in five years. From our archives, a crash killed a 34-year-old man in 2014, also on the northbound side, where 30-year-old Nathaniel Hammer died in 2013; less than 24 hours after that crash, a 52-year-old motor-scooter rider was killed in a crash. On the southbound curve at that end, 48-year-old West Seattle musician/therapist Lisa Mills was killed in 2012.
1:50 AM The highway has reopened.
ADDED 4:35 PM SUNDAY: From SPD Blotter:
Police were called to investigate a fatality collision on the Alaskan Way Viaduct around 9:40 p.m. last night. Preliminary indications are that speed played a factor in the collision.
According to witnesses, a 22-year-old man was traveling in the northbound lanes of the viaduct when he lost control of his motorcycle, struck a concrete barrier, and fell to the surface streets below.
Seattle Fire Department medics provided emergency care at the scene, but were unable to revive the man.
Traffic Collision Investigation detectives responded to the scene, processed the collision site and collected evidence.
This is an active and ongoing investigation. Information is subject to change as the investigation proceeds.
