The frontage remained flood-prone, and in 1846, Governor Juan Manuel de Rosas had a contention wall six blocks long built along the paseo. Inaugurated in March 1848 as the Paseo Encarnación Ezcurra (in honor of his wife), Rosas had it renamed the "Paseo de Julio" that October in honor of the Ninth of July, date of the Argentine Declaration of Independence (the road's southern half was renamed "Paseo Colón", in honor of Christopher Columbus, in 1857). An English Argentine investor, Edward Taylor, opened a pier along the promenade in 1855, and the flood-control walls were extended northwards to Recoleta, and south to San Telmo, in subsequent works completed in 1865.
