Yards on top of Wide Arched Bridges, etc. ?

[Capt. Grimek]

I have a small-medium sized yard with a turning wye.  I was wondering if yards were every mounted atop super wide arched stone bridges, raised above city areas on concrete pilings (steam era), etc.

I considered a Keddie Wye idea for the wye itself but is there any realistic way to have the yard supported

so that rear trackwork and scenery can be seen underneath it?

The yard is about 24" wide and about 4' long (not counting the wye).

I've stopped in Spokane, WA at night to pick up a sleeper car on something like this but couldn't tell if there were any/many switches/turn outs suspended up in the air, up there or just stub tracks.

Thanks if anyone knows of anything I can check out or can post some pics.

Here is a Bing map of North Milwaukee, WI.

The wye (start of the famous Beer Line) curves off the the right, up over 32nd St. and a stream.  The north leg is also visible, with a business occupying the space within the wye.

To the south the yard is raised up above street level.  Capitol Ave is roughly the other end of the yard, and goes under it.  You would have to scroll down a bit to see that. The line is grade separated all the way down to Miller Brewing. 

Down in Chicago some of the yards are elevated as well.  Might have to explore some of those via computer.

Having the whole yard up on pilings might be a bit much, but having roads pass underneath might allow enough viewing ports to allow seeing the other tracks.
