Pond Boss Forums GENERAL QUESTIONS Property Projects & Construction Renovating an old rail road bridge?

I wont be using hemlock for the joist, i want something to last- if the RR ties don't work out i will use 6x6 PT for the joist. I don't mind using the hemlock for the decking since it will be a lot easier replacing a board then having to tear up the whole thing to replace a joist.
