A Billings man died early Sunday morning after crashing his motorcycle at the North 13th Street underpass, according to the Montana Highway Patrol.
Just after 12 a.m. on Sunday a 53-year-old man was driving his motorcycle eastbound beneath the underpass when he crossed the center line of the road, and braked while approaching the bend of the underpass. His motorcycle tipped over and slid onto the outside of the curb and on the right side of the road, MHP Trooper Josh French said.
The man hit his head on the curb, and was not wearing a helmet which was a contributing factor to his death, French said. He was pronounced dead on scene.
The underpass was closed off to traffic in both directions while investigators worked.
Speed did not appear to be a factor. An investigation showed that the man was driving under the influence of alcohol, which contributed to the crash according to an MHP crash narrative.
Yellowstone County Coroner Cliff Mahoney said they are not releasing his name until his next of kin can be notified.
The Billings Fire Department, Yellowstone County Sheriff's Deputies and Montana Highway Patrol responded to the crash.
