Monitor Pass southeast of Lake Tahoe opens; latest opening in 13 years
May 10, 2017
After barely closing at all during some of the worst drought years, Monitor Pass opened on the latest date in the last 13 years on Monday, according to the California Department of Transportation.
California Route 89 between Highway 395 in Mono County and Highway 4 in Alpine County is a popular tourist route.
Monitor Pass was closed for the 2016-17 winter season on Nov. 30.
According to records dating back to 2004-05, Monday’s opening marks the latest date that Monitor Pass has opened in the past 13 years, as well as the first opening day during the month of May. The previous latest-opening date of Monitor Pass occurred April 29, 2011, during the 2010-11 season.
The pass didn’t close at all during the winter of 2014-15, according to the CalTrans Web site.
Heavy snow in the Sierra has delayed the opening of several passes over the mountains.
