As part of Bellevue’s Mountains to Sound Greenway trail project, the northbound and southbound ramps from I-405 to eastbound I-90 will be closed from 10:30 p.m. Friday, June 19, to 5 a.m. Monday, June 22.
The weekend ramp closures are needed to construct a pedestrian and bicycle tunnel under the eastbound I-90 on-ramp. The overall project will improve safety for Mountains to Sound Greenway trail users, as well as for drivers using a different ramp from I-90 to Factoria Boulevard.
Weekend travelers on I-405 in Bellevue should plan ahead to identify an alternate connection to reach eastbound I-90 during the closure. The Bellevue Way and Northeast 150th Street on-ramps to eastbound I-90 will remain open.
The I-90 Trail for pedestrians and bicyclist will remain open all weekend; the I-405 Trail, from Southeast 38th Street to the I-90 trail, will be closed, with a signed detour in place.
