Washington State Department of Transportation Variance Request 

The Seattle Department of Construction and Inspections (SDCI) has received an application from Washington State Department of Transportation for a Major Public Project Construction noise variance from the standards for nighttime construction noise for above-ground construction activities in support of the SR 520 Montlake Phase of the Rest of the West Design-Build Project. This phase, known as the Montlake Phase, includes construction of the West Approach Bridge South (WABS), Montlake lid and interchange, and a bicycle/pedestrian land bridge over the highway. Construction of this first phase of the I-5 to Lake Washington Project (also known as the “Rest of the West”) is scheduled to begin in 2018. The existing SR 520 west approach bridge is built on hollow columns, which are vulnerable to a catastrophic earthquake, and the roadway has narrow shoulders and lacks transit/HOV lanes. The WABS will connect eastbound traffic from Montlake to the new floating bridge. It will also feature a dedicated transit/HOV lane that will provide improved mobility for buses and carpools as they access the new floating bridge and continue to the Eastside.


Washington State Department of Transportation’s application includes a list of the proposed nighttime operations, necessity for nighttime work. Washington State Department of Transportation proposes new nighttime limits for on-site construction noise created at night, and applies only to the Montlake Phase of the Rest of the West Design-Build Project.
