The large remaining section of the city was urbanized to modern standards: wide roads, regular blocks laid out orthogonally, and lots with large dimensions - However, the port neighborhoods were kept, to a certain extent, at the margins of the city, because while the central nucleus suffered heavy verticalization, Saúde, Gamboa and Santo Cristo maintained the same form - Afterwards, in the 1960s and 1970s, the construction of the Viaduto da Perimetral (Perimeter Viaduct) strengthened the rupture, separating even further these neighborhoods from the rest of the city.

Presented by rio de janeiro's prefecture, the study Rio de Janeiro: uma cidade conectada por túneis (rio de janeiro: a city connected by tunnels), by Ronaldo Cerqueira Carvalho looks at the many urban tunnels in the city of Rio de Janeiro and shows a wave of influences expanded by the advent of each one of the carioca tunnels, on the prism of socio economics, cultural and humanists connections, mirrored and catalyzed by the flux that these passages make viable - tunnels in the districts of  copacabana, leme, botafogo, laranjeiras, catumbi, rio comprido, gamboa, saúde, santo cristo, tijuca, vila isabel, barra da tijuca, são conrado, and joá are examined, among others.
