The Idaho State Police is advising that travel is very dangerous on Interstate 90 and State Hwy 3 in the 4th of July area.  With the heavy amount of snow accumulations and more snow falling, trees are overloaded and falling onto road ways: "We are requesting motorists in these area to be aware of the these dangers and to not travel unless it is absolutely necessary," the ISP said in a travel advisory. "The Idaho Dept of Transportation is in the area trying to clear the trees as quickly as possible.  Please use caution."
