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