What about similarly populated cities?
In new street additions, Iloilo City fluctuated in its street-construction patterns, while Zaria built increasingly disconnected streets over time and Zurich built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full street network, though, all three cities follow the same trend. Iloilo City and Zaria have been growing further apart in their street-network character since 1975.
