What about similarly populated cities?
In new street additions, Ping'an built increasingly disconnected streets over time, while Murliganj built increasingly disconnected streets from 1975 through 1991-2005, then improved and Tivoli built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full street network, though, all three cities follow the same trend. Ping'an and Murliganj have been growing further apart in their street-network character since 1975.
