New post on http://twitter.com/caltransdist3 : Caltrans & first responders are working as quickly and safely as they can to clear a jackknifed big rig on EB I-80 near Cisco & multiple spinouts along the Donner Pass corridor. At this time, there is no estimate how long it will take to clear these incidents & reopen the roadway http://pic.twitter.com/TK6SoK5mxs
