Riachuelo Street (Portuguese: Rua Riachuelo) is a public road in Porto Alegre, in the Brazilian state of Rio Grande do Sul. Located in the historic center of Porto Alegre, it starts at General Salustiano Street and ends at , in front of the .
Riachuelo Street is one of the oldest streets in the city, and it was laid out in the townâÂÂs first plan, drawn up by Captain Alexandre Montanha. From Ladeira Street (now ) to Arsenal Beach, it was known as Cotovelo (English: Elbow) Street due to its layout, which formed a large bend behind the São Pedro Theater. From Ladeira to Portão Square (now Conde de Porto Alegre Square), it was known as Ponte Street because of the bridge at the corner with Borges de Medeiros Avenue.
The section known as Ponte Street had serious flooding problems, so much so that in 1830 a councilor proposed that work be done on the streets that needed to be drained, to fill in those that required it, such as Poço Street and Ponte Street. To this end, he suggested that the provincial government use the labor of convicts. On Cotovelo Street, the biggest obstacle was the existence of a quarry at the corner of Clara Street (now João Manoel Street), which remained there for eleven years, from 1833 to 1844, when it was finally dismantled. In 1843, when the streets were mapped, the road was renamed Ponte Street. This name was changed in 1865 to Riachuelo Street, in honor of the Brazilian naval victory over the Paraguayan squadron in the naval battle of Riachuelo.
Riachuelo Street was home to several noble residences, including the first house in Porto Alegre to have glass windows, which caused great concern among the population, who were used to hiding the interiors of their homes. This house belonged to Manuel Marques de Sousa, the Count of Porto Alegre, and , the Baron of JacuÃÂ. In 1886, the União Telefônica was installed at the corner of General Câmara Street, where the public library building was later constructed.
The 1892 building statistics recorded the dense population of the street, typical of the central zone, totaling 349 buildings, 270 of which were single-story, 44 townhouses, and 35 semi-detached houses.
