With the 1910 Chile Centennial celebrations, many urban projects were undertaken. The railway network was extended allowing connection of the city with its nascent suburbs by a new rail ring and route to the Cajón del Maipo, while a new railway station was built in the north of the city: the Mapocho Station. At the Mapocho river's southern side, the Parque Forestal was created and new buildings such as the Museum of Fine Arts, the Barros Arana public boarding school and the National Library were opened. In addition, the work would include a sewer system, covering about 85% of the urban population.
