as you can see the SP had no qualms about mixing steel and wood this bridge /trestle in near holtville Ca. they beefed up the steel with wood pilings in affect making it a trestle of sorts. there is another trussed bridge in the phoenix main that has a trestle approach on one end will get a photo of it and post later.
