The Treacherous Road

The Treacherous Road is a main quest in the Fallout: New Vegas add-on, Honest Hearts.

Detailed walkthrough
The easiest way to finish this quest is to disarm the bear traps, since there are only six on the bridge, and because there are not many enemies guarding them.

If you choose to kill the White Legs sappers, the quest will be somewhat harder because they travel in groups. Two of the White Legs are in a large group to the north, and one is in a smaller group to the south.

Whichever path you choose, you can still go back and disarm the traps or kill the White Legs (whichever you didn't choose) after the quest is completed for extra experience.
