Looking at the aerial photo, looks like the approaches to the through girder, are about half the length, each. I guestimated the total to be about 130-140' . The support looks to be....a single support for the deck bridge approaches, with two columns added, at each end, and slightly higher, for the through girder......have fun with that! 
We always learn far more from our own mistakes, than we will ever learn from another's advice.
The greatest place to live life, is on the sharp leading edge of a learning curve.
Lead me not into temptation.....I can find it myself!
