On February 17, 1867 the Paseo officially opened to the public while work continued on it. By 1870 it had tree-lined pedestrian medians between "el Caballito" and the Palm Tree Roundabout, carried out by the Ministry of Development under Francisco P. Herrera. Between 1872 and 1876 an eight-meter bridge was built at Hacienda de la Teja and the pedestrian medians were completed all the way to Chapultepec. Eucalyptus and ash trees and willows were planted and four monumental roundabouts ("glorietas") were built between the Palm Tree Roundabout and Avenida Juárez. In 1872 the boulevard was renamed Paseo de la Reforma. On its flanks, upscale subdivisions were built, Colonia Americana – today Colonia Juárez, and Colonia Cuauhtémoc. The French style of the area was epitomized at the time by frequent comparisons of Paseo de la Reforma to the Champs Elysées in Paris.
