This is not a road a normal car could drive down. Did the path on a bicycle in August 2020. It's two tracks of sand / dirt with deep ruts and low branches overhead. Even biking it was difficult, it would be impossible for even a jeep to manage this
This bridge does not exist - They want to build a new one but in June 2020 nothing, not even the old bridge, is there. It's water. https://www.greatworksbridge.org/
