Why did WSDOT rebuild SR 530?
Both directions of SR 530 in North Snohomish County from Whitman Road (milepost 36) to 310th Street Northeast (milepost 39) were blocked following a massive landslide that occurred on Saturday, March 22. Debris from the slide damaged SR 530 and blocked the north fork of the Stillaguamish River.
The end result
Due to the risk resulting from the landslide and the geographic changes to the Stillaguamish River North Fork, the roadway was elevated. The design/build contract was awarded to Guy F. Atkinson Construction.
Contractor crews working for WSDOT reopened ahead of schedule on the evening of Monday, Sept. 22, 2014.
Contractor crews reconstructed SR 530 in four major stages:
COMPLETED - Stage 1: Repaired, paved and restriped the existing roadway so that it can open temporarily to two-way traffic within the first few weeks of the project.
COMPLETED - Stage 2: Rebuilt the east section of the roadway next to the existing roadway.
COMPLETED - Stage 3: Rebuilt the roadway through the slide area and the west side of the roadway next to the existing SR 530.
Stage 4 - Finish other key tasks off the roadway, including landscaping, stream restoration and demolition of the existing roadway, after the new SR 530 opens to traffic.
The SR 530 reconstruction project is funded with $28.1 million of Federal Emergency Relief funding.
