Smallest Bridges

Sykotyk:
I just had a general thought that I don't think we've delved into before. We all can talk about the tallest, longest, oldest, etc bridge. But, what about the smallest?

For instance:

A) What is the smallest suspension bridge (that's not simply decorative)
b) Smallest Through Truss bridge?
c) Smallest through arch bridge/arch truss bridge?
d) smallest draw bridge (height of rise--if not swing decks--or drawspan)?

I was down in Louisiana a few days ago clinching the state of parishes, and went over many draw bridges, some were surprisingly narrow and close to the waterway. Never really thought about it before.

I'm sure there's some culverts out there built as absurdly small bridges out there rather than placing a pipe, filling around with dirt, and paving over.

there's about a 30 foot long suspension bridge crossing a stream in someone's backyard off 395 in Modoc County.  it supports a four foot wide walkway.  probably just a guy who likes tinkering.

SteveG1988:
In my home town there is possibly a 6 or 7 foot long plank bridge across a lake.

It crosses like a viaduct upto that section and is signed as "turtle Log bridge"

Alps:
I've seen 20 foot (or less) pony trusses for people's driveways to cross the culvert next to the main road. There's a small suspension bridge in Alaska, actually on my site for AK 98, that only has a single pier it's so small.
