Airport–HSR hub with mixed-use CBD
Integrates aviation and rail hub urbanism
Shanghai Hongqiao Business District, planned from 2009 by the Shanghai municipal government, is a mixed-use central business district built around the Hongqiao transport hub in the city's west, where the airport, high-speed rail station and metro lines converge in a single interchange complex. The plan arranges dense office, exhibition and commercial quarters directly over and around the hub, positioning the district as a gateway serving the Yangtze River Delta region rather than Shanghai alone.
Hongqiao is one of the most ambitious realised examples of hub-based urbanism, integrating aviation and high-speed rail with district development at a scale few cities have attempted. It has become a reference point in discussions of the aerotropolis and of China's strategy of using inter-city rail accessibility to organise polycentric megaregional growth.
