arch bridge is strongest, as in stirty, but thats not always a good thing, think of it this way, if you take a branch off a tree, its soft right. so wen you bend it vigouresly, it wont break. but if you take a dry branch. it will snap. so truss is most likely ur best answer because it shows some flex and some stirtyness and it alowes wind through it easily.

A span bridge is basically a flat plate with its ends held rigid. This is the weakest bridge type, since it depends entirely on the deflection of the beam.
An arch bridge is stronger, because the load is distributed along the curved "arch" to the end points. However, there is still a fairly long span where the beam deflection may be the deciding factor.
A truss bridge has several short interconnecting lengths that effectively distribute the load over (almost) all points simultaneously. This makes it the strongest bridge in terms of vertical loading.
However, there several types of loading, including wind shear. An example where this load was ignored would be the original "Tacoma Narrows" bridge. How your bridge is designed to withstand ALL possible loading factors will determine which is the "strongest".

Are you going for strength purely or a strength weight ratio? I'd say hot glue vs. the little bit your saying you'd bother with on white glue hot glue is better. If you would wait white glue is better as it seeps into the wood far more and holds it together better than the strength of the glue alone=hot glue. Triangles are better as the materials are the same and arches don't work to well with popsicle sticks. AND they are the strongest shape I deleted my lower post part and changed it to this since you changed your info: --- I would use a triple fink truss or something similar with the design looking like below and in source /\/\/\/\/\/\/\ the key is that the triangles steadily grow larger as in the picture with similar angles and your middle triangle is larger so that you can slide your most likely square weight block in and than add the chain which will hang attached to the load at bottom.

A truss uses less material than the other types of bridges. A suspension bridge uses even less. So, they are the strongest based on strength/amount of materials necessary.

The Arch why do you thing the romans used the arch in everything and everywhere.
