Good luck getting past all of the Wyverns and making it to the ladder alive. However, there is a certain distance where they will take some damage from a bow and not aggro. If you have decent dexterity, and are using either the Longbow or Black Bow of Pharis, then you should be able to kill them with a reasonable amount of Standard Arrows.

For closer range, take on one at a time and try not to engage them on the bridge. pyromancy is also an effective strategy.
