A single urban ring road is an efficient means to manage traffic and delimit development. But each successive ring introduced into a fast growing city diminishes flows of movement, encourages uneven patterns of settlement, and costs much more to build. Replacing the concentric ring road logic with a ‘two-halves’ model establishes a clear plan for development that respects the traditional north-south axis while better managing local resources. In the case of Chengdu – which is located in one of the few Chinese regions where agriculture is economically viable – the fertile soil to the west is utilized for much needed crop production. A crescent defines a zone for farming and limits urbanization around rivers originating from the province’s western mountain range. On the eastern half, the city is zoned for commercial, residential, and industrial uses along the interregional infrastructure corridor. A ‘loopy’ road connects future urban nodes preemptively eliminating the need for additional rings.
