California's Route 254554. Route 254 is the Avenue of the Giants, comprising a portion of the former Redwood Highway through and connecting a number of state park units, from Route 101 near the Sylvandale interchange to Route 101 south of Stafford.
Is this the route which has, or had from what I've heard, that big redwood tree where the route goes through it by a tunnel? Or is it Route 101.
