What's with this pipe?

Does anyone know why this pipe has its own bridge? What does it probably carry?

Very likely either freshwater or sewage. Lack of 'giveaway' hazmat signs makes me think freshwater. "Light Blue Paint" only makes me think that the local municipality didn't want a huge eyesore of a pipe painted 'Day-Glo Emergency Orange' or 'Nuclear Meltdown Green'. No regs on these things that I'm aware of.
Saw 'em all over the place in S. Miami/Perrine/Cutler Ridge/&c area where I grew up. Pretty much anywhere a pipe had to cross a canal.
It has it's own bridge to provide support. "Liek, duh?" ;)

It's a maintenance thing. If the pipe is in the air it will not corrode as quickly as when it is submerged. It can also be painted, and repainted, much easier. It can also be inspected much easier on a regular basis, and if it should burst it will not only be bleeding obvious where the break in the pipeline is, it can be repaired much easier. Contrast all of these to 'if it were underwater', in which case any/all of these things would start with "First, get a team of qualified Divers..." which jacks your costs up by a factor of A-Lot before you've even started.

If it's under the surface of the canal at the same depth that it is under the ground, it will be nigh-invisible to any boatcraft, but sooner or later one of them will come along and burst it. Yes, they're not supposed to be there in the first place, but since when has that ever stopped anyone? To go deeper than that involves digging under the bottom surface of the canal, which suxorz.

Ergo, put the pipe above the surface of the water, which means raising it high enough that gators, canoes, small repair boats can navigate under it. Which means it gets its own bridge.

Makes sense to me. Thanks!

Because if it was a natural gas line it would likely be festooned with "Don't Even THINK About Bringing A Flame Within A Thousand Yards Of This Pipe" signs, plus the odd emergency pressure release valve or three that gas lines always seem to have.
