Return to the Central Yharnam lamp, take the left stairs to deal with the Huntsman’s Minions, and ride the elevator to reach the other bridge.

As you walk forward a group of enemies will attack, but what you really need to watch out for is the flaming boulder that is pushed from the end of the bridge. Avoid the boulder by hiding in one of the balcony areas of the bridge and then deal with the remaining enemies.

Head up the stairs to defeat the Huntsman’s Minion and shielded Huntsman, again, and continue up the stairs and ignore the enemies on the right that will not aggro you to enter the Tomb of Oedon.
