The Interurban Trail of metropolitan Seattle, Washington runs about 30 miles from north Seattle to Everett, Washington, roughly following the route of an old inter-urban trolley. Parts of the trail are under construction, and parts are either bike lanes or short sections on residential streets. Note: there are other trails in the area that are also called Interurban Trail, unfortunately not connected with this trail.
Update: We rode the length of this trail recently (August 2010) and got a GPS trace of it. It’s now mostly complete, and the signs have been much improved in Everett (Lynwood still has a few confusing spots).
