Ghâsh Road

The Road of Fire, or Sauron’s Road, ran from the Dark Tower’s huge western gate over a deep abyss by a bridge of iron, and ran straight for a league between two smoking chasms, and then to a long sloping causeway up onto the eastern side of Mount Doom, and after encircling the mountain came to the Sammath Naur. The road was constantly repaired by countless [slaves. Lava from the mountain was also channelled back to Barad-dûr next to the road in the Naur Trench, filling the gulf around Barad-dûr except for the great Iron Bridge, it was used as a final defence of the Dark Tower, and also to feed the fires for the various engines in the Tower, the Trench ran virtually straight and parallel to the road.
