Tree removal station site to 112th Avenue Southeast

Beginning as early as next week, Sound Transit's contractor will resume clearing trees and understory vegetation in the Sound Transit work zone along Bellevue Way Southeast, between the station site and 112th Avenue Southeast. Trees located where the light rail route will be built need to be removed in order to build the project. Sound Transit has worked closely with the City of Bellevue and Washington State Department of Ecology in development, review and approval of plans for clearing trees and understory vegetation.

The preservation of trees to the maximum extent feasible has been a primary project goal throughout project design and into construction. Throughout the corridor, trees that are in close proximity to the work zone but not be negatively impacted by construction or light rail operations will be preserved with protective fencing.

Night work between ramp to I-90 and I-90 roadway

Overnight on Tuesday, Oct. 24-Friday, Oct. 26, from 9 p.m. and 5 a.m., Sound Transit's contractor will pour roadway pole foundations between I-90 and the Bellevue Way Southeast westbound on ramp. A shoulder and lane closure on westbound I-90 is necessary for this work to occur. Crews will minimize noise, dust and debris to extent possible during the work. Noise impacts from this work are expected to be minimal.
