I am sorry if this is an old topic - I am on tour, and only have a Kindle, and topic searches are torture.
No problem. Hope you don't mind that this reply is recycled, then:
Here's a pertinent link to an old forum post that contains other pertinent links to other older forum posts:
http://www.adventurecycling.org/forums/index.php?topic=9240.msg46341#msg46341I do recommend taking the 202/47/Banks-Vernonia trail into Portland. It is very rural and very quiet in terms of traffic and people. Links to maps:

http://www.portlandonline.com/transportation/index.cfm?&a=316550&c=36638I've never taken 30 the full way from Astoria to Portland, just the portion from Portland-Rainier and Clatskanie-Wesport, so I've missed the worst parts of US 30. But even that little bit makes me prefer the 202/47/Banks-Vernonia routing.
There aren't many services, but there's just enough. Make sure you're stocked when leaving Astoria, as there isn't another full service grocery until Vernonia, about 70 miles down the road. Only a couple of country markets with short hours in between.
The route from Astoria to Hillsboro (Portland westside suburb) is 100 miles. You can break it into two days by camping at Big Eddy County Park which is about 60 miles in. Few, if any, lodging options are found on this route so if you are doing a credit card tour you should be prepared to do the 100 miles in a straight shot. Possible, but there are two small passes to contend with on the route.
