Hi Greg;
The horizontal cross beam between the vertical I beams do not appear to be subsantial enough to support the lengthwise I beams. By my reckoning you should have used a section of the lengthwise I beam material as a cross beam with end plates welded to the ends to facilitate bolting to the vertical I beams and with a thick shear plate welded underneath.
The loads of the outer I beams would be transferred to the mid point columns, but I do not like the look of the current crossbeams and their ability to carry the load sideways to the columns.
If on the otherhand you have simply copied what the prototype bridge was made of then well and good but it still appears to be undersized, but hey Im no engineer.
