Description 

The timber portion that is above the deck does not contribute to the load bearing structure, it is cosmetic only. The concrete box beams under the deck carry the load. The sides sort of look like a truss web, but would not be effective at supporting a span this long, nor does it match the pattern of any functional truss.

Sleepy Hollow Covered Bridge 35-48-A
Posted June 28, 2017, by Michael Quiet (mquiet [at] gmail [dot] com)

Hello Paul,

I think one of the problems is that this isn't a 'real' covered bridge, as it looks the National Bridge Inventory identifies this as a pre-stressed concrete beam. There are quite a few of these around, and it gets kinda tricky to assign a genuine covered bridge truss type to them as they generally are more stylized and only loosely conform to the real patterns.

Generally I try to avoid assigning historic truss types to these as I feel that it might muddy the waters for others researching/visiting genuine covered bridges. For example this one up in my neck of the woods: http://bridgehunter.com/ny/essex/kissing/ has a resemblance to a Town Lattice, but since it doesn't work as one and is only decorative I think its inappropriate to pass it off as such. Instead I simply identify it as a covered plate girder, since the actual bridge is a plate girder type. Therefore on yours I would refer to that as a Covered stringer bridge, with a notation that the roof support has a truss like appearance, as it doesn't directly conform to any genuine type.

Hope that helps!

-Michael

Greetings!

I'm checking the facts for website and book I am writing and this bridge is listed here as a Multiple Kingpost. However, it doesn't appear to fit the descriptions, drawings, and other photos I have of Multiple Kingpost bridges.

However, because I am not an engineer nor an expert in covered bridges, I would like any information you might have that may have as to would make this bridge a Multiple Kingpost.

You may check out my listing of the bridge at https://ohioscoveredbridgesbypaulfarrier.wordpress.com/2017/...

Warm regards,

Paul Farrier
