What about similarly populated cities?
In new street additions, Lalpur built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Araria built increasingly disconnected streets from 1975 through 1976-1990, then improved and Tver built increasingly disconnected streets over time. For the full network, Lalpur and Tver both became progressively more disconnected, while Araria grew more disconnected from 1975 through 1976-1990, then improved. Notably, Lalpur had a more connected network than Araria in 1975 but the two have since reversed their relative ranking.
