The little skecth didn't work. All got left adjusted. The girder is 12" deep for the first 8 1/2 feet. 24" deep for the center 16', and 12" deep for the last 8 1/2 feet.
That's what I was trying to show.

A picture is worth a thousand words. The light bulb is now on. Now that I am up to speed, let me talk to the owner of the lumber tomorrow. Boy we went through some changes on that one here.

Just so you understand, we can make that work out of the 2 55' timbers he has available.
If that works out, use 4"x6" stringers at 2'0 c/c between the girders, with 2x8 deck boards accross the stringers for the length of the bridge.

we are talking about two different guys. The guy with the 55 footers does not want to cut them but he will if this other guy does not work out.

Beagle, If you have Powerpoint or even MS Paint you can draw the plan and save a jpg image that can be posted with your pictures. I did it for a logging grapple.

Thanks, I didn't think of that. Would definitely be easier than babbling back and forth. It's that whole picture and a thousand words thing.

Went by the lumber man and ordered two 12" X 40' treated poles to be delivered next week. Each are marine treated and very nearly straight. They start out 13 1/2" and taper to 8 inches. gone for the weekend.

You should have a good base to sit them on so they will stay dry.

I'm sure you understand that the tapered poles won't span the 32'. Curious as to what you are going to do with them. With the taper, we could use them as masts for a cable stayed span, but not sure that's what you had in mind.
Feed my curiosity. What ya going to do with the tapered timbers?

They are 40'ers you dont think that we could cut of the last 8' and have something that would work for the span.
They are treated for marine use in salt water. This taper would make them 13 1/2" on one end and 10" on the other. Not to late to turn off the order.
