- TOUTLE – Three years after a landslide cut off access to the upper stretch of State Route 504, also known as Spirit Lake Memorial Highway, work is set to restore a key connection to one of Washington’s most scenic destinations: Mount St. Helens.
Starting Wednesday, April 15, Washington State Department of Transportation contractor crews will begin work to permanently replace the SR 504 Spirit Lake Outlet Bridge and restore access to the Johnston Ridge Observatory in the Mount St. Helens National Volcanic Monument, east of Toutle. - BELLINGHAM – After nearly one month of work to stabilize a landslide south of Bellingham, the Washington State Department of Transportation expects to reopen all lanes of northbound Interstate 5 by 5 a.m. on Thursday, April 16, pending final evaluations by geotechnical engineers.
- LEWIS COUNTY – Work on Interstate 5 in Lewis County resumes this spring as crews move from paving the roadway below to repairing the bridges above. This work, along with two additional paving projects in the area, is expected to wrap up by October. Most lane closures will happen at night to limit delays, though some daytime work will be needed.
Last summer, Washington State Department of Transportation contractor Granite Construction repaved 11 miles of I-5 between Koontz Road and the State Route 507 interchange, creating a smoother ride for travelers.
