Paris is known for the non-linearity of its street map, as it is a city that grew 'naturally' around roadways leading to suburban and more distant destinations. Centuries of this demographic growth created a city cramped, labyrinth-like and unsanitary, until a late 19th century urban renovation, overseen by Georges-Eugène Haussmann, resulted in the wide boulevards we see there today. This remained relatively unchanged until the 1970s, and the construction of cross-city and periphery expressways.
