Allison Gap Bridge

[Matthyro]

This 32inch bridge spans the Allison Gap on my MAT main line. It is actually a duck under entry to my layout.
The height from the floor is 57 inches.
It is named after NARA member #48

Great going Robin. Keep it up.
I haven't done much on mine lately as I have been sick in bed. Better now and will try to go to work today.

COOL Robin! (& quite an honor! )

Wow, that scales out to be...lets see...about 400' long, & ALMOST 800' HIGH!!

Got any more pics? (maybe a side view?)

Thanks, my friend! That's really nice!

Here is a side view. In the background are the stairs coming down to the basement.
I didn't say previously but this bridge is made out of cardboard.

Here is a closeup that shows the girder detail. Made out of cereal box cardboard cut in 3/16inch strips. Two strips joined by dividers make up a girder.

Failed to mention that it's built from cardboard!!!
WOW! absolutely superb Robin.
You have a gift with the material that my favorite midnight snack comes in. Frosted Flakes....their grrrRRREAT.

Is the entire bridge cardboard?

Unbelievable!!

Y'know, I was going to ask if it was cardboard, but then I thought , "NAAAA...couldn't be..."!

You are truely one amazing modeler, Robin!

 

[Matthyro]

Yes t. the whole thing is made of cardboard. The two main beams are a sandwich of corrugated cardboard and a skin of cereal box cardboard. When beams and girders are glued together it provides amazing strength. The engineering principals work the same as the real thing.
The more I work with cardboard the more I like it.
Thanks for the support you all give me.
Makes me want to do more

NICE bridge Robin!! WOW cardboard 32"...does it sway when the train runs over it?

Hi Ima, The bridge is very firm and doesn't move at all. The Gauge doesn't like us to have the same posting in more than one place so won't duplicate these pictures.
I am currently working on a couple more bridges which I will post in the Bridge thread.
