In new street additions, Arinodai fluctuated in its street-construction patterns, while Madhugiri built increasingly disconnected streets over time and Huoshan built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Arinodai and Madhugiri both became progressively more disconnected, while Huoshan became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Arinodai had a more sprawly network than Madhugiri in 1975 but the two have since reversed their relative ranking.
