Actually, we do have two units. One of them is a four span continuous unit, and the other one is a single span trapezoidal thing that is a nightmare unto itself. That's five spans total with four integral cross-beams. There's got to be a joint somewhere. The simple/trapezodial span will be framing into an existing bridge.
I'm not sure you would want to look at a picture of it. I've got a picture of it and I don't particularly like looking at it.
For the 4-span unit...
FYI span lengths are 105-136.5-136.5-105.
Radius of Curvature is 899.5 ft at the centerline
9 girders spaced at 8'-9" = 70'

What have you got, two continuous units?
My first question would be "are you SURE you have to have the joint? Can you not make it a four span unit?"
I can think of reasons why not, but I don't have the whole picture.
