In new street additions, Siyana built increasingly disconnected streets over time, while Akinima built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Amrit fluctuated in its street-construction patterns. For the full network, Siyana and Amrit both became progressively more disconnected, while Akinima became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Siyana and Akinima have been converging in their street-network character since 1975.
