Get-Away-Day Traffic Ugly

Friday afternoon traffic is normally bad, but you add a Monday holiday to the mix and a stalled big rig on the Altamont, and you have a bad start.  Just before 2:00 the emergency braking system on a big rig locked up bringing it to a halt in the eastbound #4 lane at Greenville.  A heavy duty tow is on the way, but meanwhile traffic is backed up to Eden Canyon.  680 is showing normal backup from Scott Creek to Sunol and then it opens northbound to at least 580.  At the moment I-80 is closed eastbound at Colfax to Nevada State Line due to snow.  Chains required on US 50 & 88.  SR 4 closed above Dorington due to white out conditions.  Cal Trans is not recommending travel into the Sierra Nevada range this weekend due to weather conditions.  Heavy snow in Truckee at this  time with the temperature 23;  Tahoe Valley airport reporting light snow, 26 degrees and gusty wind.
