The Treacherous Road

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

Quick walkthrough
You must either disarm the traps on the Old Rockville Bridge (immediately ends the quest), or kill the White Legs planting them.

Detailed walkthrough
The easiest way to finish this quest is to disarm the traps, since there are only seven traps on the bridge, and not very many enemies.

If you choose to kill the White Legs, 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. You can still go back and disarm the bear traps after the quest, but this will only give you extra experience. Likewise, you can also go back and kill the White Legs after the quest is over.
