As the weather warms back up, crews are restarting construction on Interstate 90 in Snoqualmie Pass, which means drivers should expect delays and closures through the summer.
Work resumed today on a $19 million project to replace deteriorating sections of concrete roadway and asphalt shoulders on both directions of I-90 between Cle Elum and Easton.
There will be daytime lane restrictions before Memorial Day and after Labor Day, according to the state Department of Transportation. Nighttime closures will occur from June to early September.
Construction is scheduled to wrap up by fall.
“It’s going to be one of the busiest constructions seasons we’ve seen on I-90,” WSDOT Regional Administrator Don Whitehouse said. “We understand construction delays can be frustrating, but we know drivers will appreciate smoother pavement and less congestion once we are finished.”
Later in the spring, crews will resume work on a $551 million project to build a wider 5-mile stretch of I-90 from Hyak to Keechelus Dam.
Rock blasting will be done on the slopes east of the pass. Hour-long closures will occur starting an hour before sunset.
The highway will be widened from four to six lanes.
Also included in the project, which will be complete in 2017, are replacing the snowshed east of the pass to reduce avalanche closures, replacing and adding bridges and culverts, stabilizing rock slopes and extending chain-up areas.
