I didn't find anything with a google search for this issue. NA server/ PC.

On mount riding down a body of water, ride under a bridge and get dismounted.
I first saw this in Glenumbra outside of Aldcroft (see below image for bridge location):

• I tried three different mount types - Got dismounted each time.
• Once dismounted, I cannot mount again until I get out from under the bridge.
• Disabled all addons - still happened.
• All three arches dismounted me.
• The arches are tall, so I don't think it is the game thinking mount plus character is too tall to go under. I got dismounted under bridges in Aldcroft, but I expected to get dismounted as the bridges were not tall enough for mount and character.
• Tried it on another character

The issue is not with all bridges - the one outside of Daggerfall next to the Events tent does not dismount when I ride under it.
Tried the two bridges outside of Wayrest near the Dro-Dara Plantation wayshrine. The bridge above the wayshrine dismounts you. The bridge to the left of the wayshrine is fine.

I can confirm that Aldcroft bridge does indeed dismount my character.

Very weird.

Edit: and the Dro-Dara bridges behavior is as described by OP.
