It is presumed the construction of the bridge started before Sorceress Adel came to power in Esthar. After Adel's bid for world dominion, Galbadia and Esthar entered a war and the bridge was abandoned. Engineers fleeing Esthar occupied the middle station, which became known as Fishermans Horizon.

Though the bridge appears to not be maintained, it remains usable. Laguna Loire and his friends once crossed the bridge to reach Esthar on their quest to save Ellone. Galbadia's G-Forces cross the bridge to occupy Fishermans Horizon before being driven away by the SeeD. Squall Leonhart opts to cross the bridge alone with a comatose Rinoa Heartilly, seeking to take her to Esthar to find Ellone who he believes can cure her. During their trip across the bridge, Squall shares his insecurities with her, though he knows she can't hear him. As he reaches the Seaside Station on the Esthar end of the bridge, he is met by his comrades and Edea Kramer, who want to join him.

Spoilers end here.
