Original post on May 1
An bicyclist in his 30's lost his life in a collision with a semi-truck at the intersection of S. Hanford and E. Marginal Way S. on the morning of May 1.

The fatal incident sadly coincides with the kick off of King County Bike to Work month, where commuters are encouraged to leave their cars at home and opt for self-propelled transportation.

The victim has not been identified at this time and commuters may expect delays at the intersection as police investigate.

Here are the details from Seattle Police:

Seattle Police and Fire responded to a fatality collision between a bicyclist and a semi-truck this morning at South Hanford and East Marginal Way South.

Witnesses called 911 at around 7:15 this morning informing first responders of the collision. Witnesses began giving the adult male cyclist CPR at the scene until Seattle Fire arrived, but the cyclist did not survive his injuries. Detectives from the Traffic Collision Investigation Squad (TCIS) are enroute to the location where they will process the scene and begin their investigation.
