In new street additions, Gazipur built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while San built increasingly disconnected streets over time and Satbarwa built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, San and Satbarwa both became progressively more disconnected, while Gazipur became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Gazipur and San have been converging in their street-network character since 1975.
