A man fell approximately 30 feet onto the Mercer Island light rail tracks under construction on Jan. 27, sustaining multiple traumatic injuries.

At about 12:55 p.m., a woman driving westbound on Interstate 90 witnessed the incident and called 911, according to Washington State Patrol trooper Rick Johnson. Troopers were dispatched to the scene and located the man a few minutes later. He was conscious with possible broken legs and an arm injury.

According to the Mercer Island Fire Department’s Facebook page, the man is 38 years old, and Johnson said he may be a Seattle resident. After medics stabilized the man and secured him in an aid car, he was transported to the emergency room at Harborview Medical Center in Seattle.

Johnson said troopers found some of the man’s belongings at the spot where he fell off I-90 westbound at the 76th Avenue Southeast overpass. Troopers didn’t know if drugs or alcohol were involved and are uncertain of the cause of the accident.

Mercer Island and Bellevue fire department trucks were on the scene along with a Bellevue Medic 1 vehicle. No construction workers were present when the man fell.
