I drive by this old cool bridge all the time and figured it needed a cache. This is the old milwaukee railroad bed, now owned by the State of Washington. This trail is part of the Great American Rail-Trail, a nearly 4,000 mile developing trail that will connect the country from Washington, D.C., to Washington state.
You can park within feet of ground zero. There is a pull off with room for one car, no need to cross the road. Don't forget to take a picture of the trestle!
