What about similarly populated cities?
- Saint-Jérôme, Canada
- Sungaiguntung, Indonesia
- Nyamilima, Democratic Republic of the Congo
- Hell-Ville, Madagascar
- Barra do Corda, Brazil
- El Mosha, Egypt
While Saint-Jérôme and Hell-Ville both built increasingly disconnected streets over time, Arogbo built increasingly disconnected streets from 1975 through 1991-2005, then improved in new street additions. For the full street network, though, all three cities follow the same trend.
