Assuming you are going north on I-5 to get towards OR, I usually use Hwy-20 to get over to Hwy-101. I believe Hwy-299 is also doable but I haven't gone that way in a long time. But before you commit to using Hwy-101 (whichever Hwy you use to get to it), check the road conditions on Hwy-101. I believe there have been several slides along that route which may or may not affect your ability to get through to OR (or beyond).
