I am planning my ride next summer to Alaska and considering a route that would require riding through the Anton Anderson Memorial Tunnel in Whittier, Alaska. My experience with tunnels is that they can be a little scary especially if not well lit. I would appreciate any input from any of you that have ridden this tunnel. I am concerned about how long it is, the rail road tracks in the roadway, one lane and not sure about the lighting. Look forward to your comments.
