Work continues on storm damage on Highway 20 over North Cascades

The state Department of Transportation expects to have Highway 20 over the North Cascades open by June 19.

According to a Monday news release, the second of two emergency repair projects on Highway 20 is expected to be completed about a week early that originally expected.

The release states that June 19 is realistic provided the weather cooperates and no unexpected obstacles arise.

Part of the highway inside the seasonal closure gates reopened April 30.

But the stretch between Ross Dam Trailhead (milepost 134) and Porcupine Creek (milepost 156) has remained closed because of damage caused by December flooding.

On Friday, crews began repaving the damaged sections, and expect to finish the paving work this week if the weather is dry.

Some of the remaining work, including lane striping, also requires conditions that are dry and warm enough.

Since May 13, Trimaxx Construction of Sedro-Woolley has focused on repairing flood damage between Canyon Creek Trailhead and the Granite Creek (mileposts 142 to 148).

Necessary repairs along this 6-mile section of highway included:

• Three locations where the embankment supporting the roadway needed to be rebuilt

• More than 1,000 feet of lane that was undermined or collapsed

• About 2 miles of damaged or collapsed asphalt shoulder

• About 3 miles of damaged ditch line

• About 1,000 feet of damaged guardrail and concrete barrier

• About 15 damaged or buried culverts
