The distance between adjacent streets is roughly 110 meters, greater than the equivalent Manhattan distance. The street flanking 9 de Julio to the east is called Carlos Pellegrini (north of Rivadavia) and Bernardo de Irigoyen (south of Rivadavia). The street flanking 9 de Julio to the west is called Cerrito (north of Rivadavia) and Lima (south of Rivadavia). Those lateral streets (which actually just add lanes to the avenue) are included in the 140 meter calculation.
 

The avenue was first planned in 1888 with the name of Ayohuma, but works started on the 9 July 1937. The main stretch of the avenue was completed in the 1960s. The southern connections were completed in 1980 as part of the construction of the tollway system,
 

Crossing the avenue at street level often requires a few minutes, as all intersections have traffic lights. Under normal walking speed, it takes pedestrians normally two to three green lights to cross it.
