The Glacier point road has been confirmed open and work on the Tioga pass starts today. The weather looks very nice and going by the flow of those falls the snow is melting fast !
I have also read that the projected opening date [weather dependent] for Sonora Pass [Highway 108] is for April 20th which which would be the earliest recorded on CA.gov. Monitor Pass [Highway 89] is open and has been since Jan 13th, it usually opens sometime in April !!
