A semi driver was killed Friday night when his truck and trailer went over the side of an elevated off-ramp and landed upside down on the highway below.
That driver has now been identified as Alan Mooney of Federal Way. The crash happened at about 9:30 p.m. in the Bothell area. Mooney was heading westbound on State Route 522 when he attempted to exit onto Interstate 405, according to Trooper Chris Webb with the Washington State Patrol.
"This is an elevated off-ramp that goes over the top of 405. The truck went over the edge and landed on northbound 405," said Tom Pearce with the Washington State Department of Transportation.
The truck sheared off a light pole, fell 50-60 feet and landed upside down, its trailer splitting open and spilling its contents over the freeway. The truck's cab was also sheared off, and it tumbled over the side of I-405 and fell another 75 feet to the ground below, killing the Mooney, according to Webb.
