Flying Under Bridge

That depends. If you lose GPS which is likely under a bridge, the VPS will attempt to maintain altitude, assuming you are within a certain distance from the base of the bridge. Personally, I would switch to ATTI for that. Once past, then back to GPS.
Yep. VPS does not play well with water. If you turn the VPS off before the flight it will be smoother, but all manual.

Absolutely, if you are proficient in ATTI mode. Again, only the barometer will control your "hover" altitude.
I'm assuming the bridge was over water. Keep in mind how Convective Currents work. As you fly from hot air (over land) then head over water, there is a down draft (over the water, under bridges), because the water is cooler, and this can cause your drone to drop, significantly, IF there is a stark contrast between the overland air and over water air, that is. Might explain the drop some...
OK - this is with P3P ... not a P4 ....
I found that flying under a bridge was not needed to use ATTI mode ... but switching off VPS was advised if there is water.
The time under bridge is usually short enough that GPS mode doesn't actually switch out as it seems to have a few seconds before it does. By then you are out other side and sats are back ..
As I say - that's my observation the few times I've done it.

Ken Heron does this frequently in his videos and doesn't report any issues, despite all the warnings and discussions about the dangers.
