Crossing over the Condado Lagoon, it connects the district of Condado in the barrio of Santurce with the land entrance to San Juan Islet, which is where the historic quarter of Old San Juan is located.

The bridge was designed and built by brothers Hernand and Sosthenes Behn, opening in May 22, 1910.

The Behn Brothers, Hernan and Sosthenes, arrived at Puerto Rico in 1906 from St. Thomas, U.S. Virgin Islands.

They were the founders of the Porto Rico Telephone Company, and decided to create a 150-acre real estate development in Santurce.

To help with the process, the Behn Brothers built permanent bridges to facilitate the access, and people quickly started calling the main bridge "Dos Hermanos".
