b) Chicago

Chicago’s transformation during the Progressive Era is often cited as a prime example of urban planning and development. Following the Great Chicago Fire of 1871, the city undertook a massive rebuilding effort, which included the adoption of groundbreaking urban planning and architectural designs. The city’s redevelopment featured improved street layouts, the creation of public parks, and the construction of new, fire-resistant buildings. The 1893 World’s Columbian Exposition in Chicago further showcased the city’s architectural innovation and urban planning. Chicago’s transformation during this period reflected the Progressive Era’s emphasis on efficiency, order, and modernization, and its legacy in urban planning is still evident today.
