The troopers are investigating a Wednesday evening crash on Mercer Island in the Interstate 90 express lanes that badly injured 52-year-old Darryl Lartch of Bellevue.
According to a press release, troopers said he was traveling eastbound in the I-90 reversible express lanes and was approaching the 77th Avenue Southeast off-ramp when the motorcycle left the roadway and struck a barrier at 9:50 p.m., ejecting the rider.
Trooper Tristan Cody said Lartch was wearing a helmet and was transported to Harborview Medical Center in Seattle, and the motorcycle he was riding, a black 2003 Harley Davidson, was towed from the scene by Mercer Island Towing.
