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