This is it Pete - jim currie - 05-24-2010

this would make a great walkway bridge (from the LoC site HAER 292) called a Hadley Papabolic Bow ( leaticular truss) only three bridges were built in this comfigureation its 136" long and too wide for a foot bridge bur narrow it up to 6 or 8" and walla a master piece. And your just the guy to do and i dont think there will be too many on other layouts. Cheers

Where is this bridge? It looks familiar.

Jim,
That Lenticular truss bridge is definitely an interesting bridge ! Unfortunately, the lower half of the structure would block the waterway ( I have to leave an 8' above mean high water clearance, to match the railway bridge ). But for that, I could use a much simpler form of walkway. I will have to see if I can create a place for that one somewhere.

It's the Corinth Road bridge, at Hadley, Saratoga County, New York, about 40 miles North of Albany. ( I did a search on "Lenticular truss bridge" ) ( I also consulted my Multiple Application Positioning Systems.....MAPS Big Grin ) There are a couple, slightly different, spanning the Housatonic River in Connecticut.

Pete yopu could use it in the standard configuration of a leaticular truss and suspend the walk way from the lower cord that differentiastes a leaticular truss from the parabolic bow with the walk way tied to the uprights in the center,so i've been told. still a nifty looking bridge either way Smile

I saw examples of that, and, while interesting, I still favor the Ft Laramie bridge style. The Eureka Bridge that you posted is still a very tempting alternative. Both it and the Ft Laramie bridge have "technical challenges". Once I figure out how to overcome those, and establish a clear picture of each, as it would appear in the scene, I'll make a final decision.
Many thanks for posting those bridges, any one would be an interesting addition to a scene, and definitely something that hasn't been "overkilled" in model form.
