In new street additions, Ahwaz and Nashik both built increasingly disconnected streets over time, while Brahmanbaria fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Notably, Ahwaz had a more sprawly network than Nashik in 1975 but the two have since reversed their relative ranking.
