Washington East on 20 or West on 20 -- US2

How soon? Plan on any camping. Constraints on day of week and time?

20 is currently closed. Weekend and commuter traffic is a bigger issue on 2 - and on I5.

Think that I'd do US 2 going east (southern leg) as it gets you into the nicer part of the country and away from Everett first, rather than having to face the challenge of heading west and the traffic getting worse as you head west from Stephens Pass toward Monroe and eventually Everett. WA 20 (your northern leg) is enjoyable going either way and traffic isn't a big deal; take your time and have a good trip! Stop at Newhalem if you can and learn the history of the dams and Seattle Light and the landscaping in the community; and if they have a boat ride on one of the lakes take that too; it's fun!
