Unique bridge?

Wyhog,

Very good follow up question.  I could have asked my question better.

I am seeking to know if there is a single large span girder bridge in the real world which also has a deck girder like sub structure built in under it, all one homogenous structure.

One bridge unit which is a siameased girder bridge/deck girder bridge.

I have a location on a new layout which must have a double crossover which is 35" long and 54" high, it must be lift out removable. I want girder sides on it to keep trains off the concrete floor but need something to hide the four switch machines, thus my interest in the lower "skirt" effect of a deck girder.

I posted here to seek resource of those who may be more aware of real RRing.  Thank you, Tom

you do have internet access. have considered using that tool too find what you think you want?

Paperboy, Yes, thank you.  I have been searching bridges for quite a while.  Even took rides to check out some of the bridges in your link.  That site was one of my first hits. Thank you.

Wyhog, Fantastic photos!  Exactly along the line of what I need.  I have Googled bridges so many nights and printed out so many cross sections of various road's specific and generic bridges but none satisfied my need the way some of your photos do. 

I was reluctant just to cobble a needed design together if by any chance there were prototype designs I could "borrow".

Thank you very much. Tom
