The state will begin work Monday on reopening the North Cascades Highway.

The Washington State Department of Transportation says it likely will be four to six weeks before the scenic highway that connects the Methow and Skagit valleys is open for traffic.

In addition to about 7 feet of snow on the highway, the Liberty Bell avalanche chutes are full and that snow will need to be removed, WSDOT said.

The state says snow levels this year on Highway 20 are higher than normal.

Last year, the pass reopened on May 12. In 2019, it was reopened April 18.

The latest reopening date on record was back in 1974, when the pass was finally cleared June 14.

The earliest reopening was April 2 in 1998.
