According to the department of forrestry it was finished August 15th or atleast thats when they put the rules out. I can't find a site for it, but it may just be because how new it is. here are directions of someone gets bored though.
I-5 north to Longview,
Cross Longview bridge into Oregon,
Take a right at end of bridge onto Highway 30,
Follow highway 30 threw Clatskinine, and Westport.
After you get threw westport you'll start heading up a huge hill (Bradley Hill to be exact)
about 1/4 mile past the bradley hill view point(top of hill) take a left
the road is unmarked as far as name. Although thier was a sign saying dirt church on it on monday. but once on it you should see huge powerlines, you know your in the right place.
If you dont have time to take a chance and explore I will head back that direction in a week or two. so I can just post lots of pictures on landmarks on the way thier. and trails of course.
Also it is mainly a quading area, but Jones Creek Trail system in Washougal is close, and lots of fun. Jeeps are aloud thier but the trail info says not reccomended, But as long as your not driving like an idiot you'll be fine. Although for Jones creek you need a permit. heres a link
Jones Creek Trail System - Washington Motorcycle and ATV Trails
if it doesn't work sign up for the site and then use it.
Sorry I am so long winded, I hope someone can find something useful in my jabber.
