In new street additions, Djougou fluctuated in its street-construction patterns, while Yuzhno-Sakhalinsk built increasingly disconnected streets over time and Pithampur built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Djougou and Yuzhno-Sakhalinsk both became progressively more disconnected, while Pithampur became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Djougou and Yuzhno-Sakhalinsk have been growing further apart in their street-network character since 1975.
