Which city is noted for having a grand complex with concentric hexagonal streets?

The city noted for having a grand complex with concentric hexagonal streets is Detroit. This characteristic urban design can be traced back to the city’s planning in the early 20th century when the layout was influenced by modernist ideas. The design aimed at promoting efficiency and organization in the urban environment. Concentric hexagonal streets allow for a more flexible and interconnected street network, which can facilitate movement and accommodate a variety of land uses.

Cities like Savannah are known for their grid layout combined with parks, while Philadelphia’s design is historically recognized for its grid plan established by William Penn. Washington, DC features a radial plan based on diagonal avenues intersecting with a grid. Each of these cities has unique urban planning characteristics, but it is Detroit that stands out in this context for its specific hexagonal street layout. Understanding the distinctions in city planning can provide valuable insights into urban development and design principles.
