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