A spring construction project on I-90 is expected to have a huge impact on drivers the next couple of weeks.
Starting Saturday, April 12, I-90 over the Snoqualmie Pass will be restricted to a single lane in each direction for two weeks as crews tear down the 64-year-old East Snowshed.
The project is part of a $551 million plan to widen the I-90 corridor from Hyak to the Keechelus Dam. Officials said the next two weeks are vital because they want to get a substantial part of the work done before summer. WSDOT expects to complete the project in 2018.
Crews will be building detours and working to eliminate the snowshed, built in 1950, before the actual bridgework can start. The project goal is to add a new lane in each direction, replace deteriorating pavement, stabilize rock slopes, straighten sharp curves and add bridges and culverts.
Officials warn drivers to expect major backups and consider taking alternate routes, such as U.S. Highway 12 over White Pass or U.S. Highway 2 over Stevens Pass.
Drivers are also urged to plan their trips ahead to avoid peak drive times, when construction could create two hours or more in delays.
For heavy weekend traffic, particularly for the Easter weekend, WSDOT crews will open two lanes going eastbound Friday and two lanes westbound Sunday between Hyak to the Price Creek vicinity.
