パリ改造
At the beginning of the 20th century, Édouard Herriot was elected Mayor of Lyon, a dominating French city outside of Paris, thanks to its dynamic industrial and commercial output. Inspired by the French hygiéniste urbanist movement, similar to Haussmann's renovation of Paris, he undertook major works to improve urban and social space. The eastward urban expansion of rail and road networks turned La Part-Dieu marshalling yards into the centre of the metropolitan area. In 1926, a project based on American Downtowns emerged.
