Travel remains treacherous and along the I-5 corridor and other southwest interior Oregon highways. Several highways are closed due to either blizzard conditions and downed trees.
As of Tuesday night, Oregon 138 east of Roseburg is closed due to blizzard conditions from Toketee east to U.S. 97. Oregon 62 from Prospect north, including Oregon 230 to Diamond Lake Junction, is also closed due to white out conditions. Oregon 255 (Carpenterville Highway), which parallels U.S. 101 between Pistol River and Brookings, is closed due to downed trees.
Chains are required both northbound and southbound on the I-5 Siskiyou Summit, south of Ashland. Caltrans is also reporting chain requirements south of the border with heavy snow, blizzard conditions and crashes near Mt. Shasta. Significant traffic back-ups have been observed on road cameras. Caltrans is holding northbound commercial trucks at Redding. Delay travel into this area.
Oregon Highways 38, 42, 42S and U.S. 101 are also reporting either downed trees or power lines, though all remain open to at least a single lane as of Tuesday afternoon.
Travel is not advised in southwest Oregon tonight. Be prepared for wind, low visibility and poor winter driving conditions until the storm passes. Motorists are urged to drive to the conditions as there have been numerous spin-outs and crashes.
