The last quarter of the 19th century, from 1870 to 1900, more clearly marked a new urban landscape of Bogotá. The constant rural migration to Bogotá had been one of the most important factors that allowed the city to maintain its influential power in the region both during the colonial ages and during the republic. In 1847, the city governor and the council tried to expand the urban area of Bogotá beyond the colonial limits, whereas, only until the 1860s was that expansion encouraged by the president of Colombia Tomas Cipriano de Mosquera. The Mosquera plan included lotting the western part of Bogotá, building bridges and wider roads and plazas, but that plan was only partially implemented. In the following decade, other urban initiatives emerged but this time from the private sector. A group of businessmen, tired of the city’s slow growth and development, proposed the construction of sewars, theaters, electric systems and new roads in order to hasten the development of Bogotá. Because of the 1876 civil war, the plan could not be implemented, but from that initiative, the council adopted the first urban code of Bogotá in 1875. These initiatives tried to update the undeveloped city to the new technologies of the 1800s; however, the pace remained slow, and only after 1882, when the train and the trolley came to Bogotá, some urban development projects progressed more quickly.
