Northbound traffic was shut down but partially reopened at milepost 310 (north of Stoneman Lake Road).

Southbound lanes were not affected. Please be aware of current traffic conditions here.

More snow is expected in some parts of the state on Friday, with a few more showers possible in the valley.
