In new street additions, Varna and Kursk both built increasingly disconnected streets over time, while Mallawi built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Varna and Kursk both became progressively more disconnected, while Mallawi became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Varna had a more connected network than Kursk in 1975 but the two have since reversed their relative ranking.
