Donner Lake, CA…Just west of Donner Lake Road on westbound I-80 a vehicle has collided with a boulder. The vehicle is now on the righthand side but Kingvale Caltrans has been notified that there are multiple rocks blocking lanes in the area. They are conducting a traffic break at this time to clear the roadway. Please use caution in the areal. At times in the spring rain can loosen rocks and snow with the increased weight. Be on the lookout for incidents of this type while the latest weak system moves through.
