It was quiet hard for me to map with the bridge type quest. So i want to share some thoughts here:
As you may know no names are provided for the pictures. i still support that as probably nobody knows the somewhat technical names for the structures. see #842
Pictures may be to big, forgive me, im new to github ^^ of course i didnt map those bridges in osm.
(1) small bridges are not represented in the pictures, so its quite hard to pick the right picture. example of a extremely dirty & closed one:


i had no idea which one to pick. if i understand the wiki correct it would be "beam".

(2)

This one is probably "beam" too, although it looks completely different.
(3)


with the wiki article in mind - is this "arch"?


Conclusion:
Small bridges are not well represented, most of them are probably beam (?), just without the pillars.
For some bridges its still hard to map, as you only have a picture, and no name or description.
I may look if other people are more sucessful than me by checking the changesets sometime & search for more bridges in my area.
It's all beam.
As a solution, we may search for another representative picture of a "small" beam bridge (perhaps not a footbridge) and when the user selects that bridge, also tag it as "beam".
Well, does not make sense to keep this open if nothing is proposed.
Can you reopen and reassign to me? I was waiting for a better weather to make photo of one of small bridges.
I tried
search for another representative picture of a "small" beam bridge
and found nothing on suitable license
(I cannot assign you)
@matkoniecz
I remember about it, I made even a special bicycle trip to one bridge that should fit bit for various reasons none was suitable.
Ok then i close it. Thanks for tge effort though ^^
