What about similarly populated cities?
In new street additions, Lynn built increasingly disconnected streets from 1975 through 1976-1990, then improved, while Syzran built increasingly disconnected streets over time and Keskin fluctuated in its street-construction patterns. For the full network, Lynn and Syzran both became progressively more disconnected, while Keskin became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Lynn and Syzran have been converging in their street-network character since 1975.
