[3/27/19] North Cascades Highway

Posted in TransportationTagged , , , ,

Forget about that groundhog. A sure sign of spring in the Pacific Northwest is the announcement that the clearing of 37 miles of State Route 20 connecting the Skagit and Methow valleys began Monday, March 25.

Washington State Department of Transportation’s east side maintenance crews cleared from Early Winters up 7 miles to Silver Star Gate – and kept going.  By mid-morning yesterday crews cleared one lane for an additional 7 miles to Lone Fir (campground). 

The barricades will remain in place at Early Winters for the time being.

The east side and west side crews expect to meet between Rainy and Washington passes within four to six weeks. The work can take longer if there is late spring snow or move more quickly if warmer temperatures accelerate snowmelt.

Once crews clear the snow, they will make necessary repairs to the highway, including guardrails, signs, stripes and pavement patches. Only then can the gates open to travelers.  The reopening will provide:

·       Another route between western and eastern Washington for travelers.

·       Access to more miles of US Bike Route 10.

·       Access to hiking trailheads and campgrounds.

During an assessment trip on Monday, March 18, WSDOT avalanche and maintenance staff found 6 feet of snow at Rainy and Washington passes; that’s 4 feet less than last year.

Public access between the closure gates is allowed during the winter months but during the Monday through Thursday clearing process, that space is a legal work zone closed to the public due to the heavy equipment used in the clearing.

In spring 2018, crews needed seven weeks to clear the highway. Clearing started on March 26, and the highway reopened on May 11. The latest opening was in 1974 when the highway reopened on June 14. During the winter of 1976 to 1977, there wasn’t enough snow to ever close the highway.
