Traversing the Pine Creek Canyon, the bridge is part of the quest Retake the Bridge, where three White Legs guards holding the bridge must be eliminated. The traps they set up on the bridge must also be disabled.
A hollowed-out rock can be found next to the bridge, on an overlooking ledge immediately northeast of the fast travel point. A second hollowed-out rock can be found next to the road immediately southwest of the second bridge to the southeast.
White Legs, as well as multiple groups of green geckos, yao guai, cazadores, and other hostile creatures, are known to spawn simultaneously on both ends of the bridge.
