In the Ramayana, what is the name of the bridge built to Lanka?

In the Ramayana, the bridge built to Lanka is called Rama Setu.

Rama Setu, meaning Rama’s Bridge, is the legendary causeway constructed so Rama’s army could cross from the Indian mainland to Lanka. The Ramayana describes the vanara forces gathering and placing stones and other materials in the sea under the leadership associated with Nala and Nila.

The bridge enabled Rama, Lakshmana, Hanuman, and their allies to reach Lanka and confront Ravana after Sita’s abduction. In modern geography, Adam’s Bridge is the name commonly used for the chain of limestone shoals between southeastern India and northwestern Sri Lanka.

Rama Setu should not be confused with the builders’ names. Hanuman was a major commander and devotee in the campaign, while Nala is traditionally associated with engineering the bridge. The epic name refers to Rama, not to a person named Setu.
