A 24-year-old man died Thursday morning when the motorcycle he was riding slammed into the back of an Edmonton Transit System bus on 97th Street near 157th Avenue.
Speed was a factor in the collision, police said in a news release.
The motorcyclist was declared dead at the scene.
Investigators believe the ETS bus, northbound on 97th Street, was struck from behind as the bus driver was attempting to turn right from 97th Street onto 157th Avenue at the time.
The scene was taped off and 97th Street was closed for several hours between 153rd Avenue and 160th Avenue. It has since re-opened.
Images of the scene showed an orange tarp beside a motorcycle that appeared heavily damaged.
An ETS bus was stopped on the roadway with its front door open, a short distance ahead of the motorcycle.
The death marks Edmonton's sixth traffic fatality of 2017.
