What are the opening hours for the Nine Arch Bridge?

The Nine Arch Bridge is open 24 hours a day, 7 days a week, since it is an open-air public infrastructure location. That said, for safety and photography, it is best to stop by only in the daylight window, between 6:00 AM and 6:00 PM.

There is no artificial lighting along the bridge, and on top of that, the jungle trails that lead to it are unlit as well. Going after dark is risky because the ground can be uneven, nocturnal wildlife may appear, and in that deep black, you simply cannot see oncoming trains.
