In new street additions, Kanchipuram and Yixing both fluctuated in its street-construction patterns, while Tangail built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Notably, Kanchipuram had a more sprawly network than Tangail in 1975 but the two have since reversed their relative ranking.
