In new street additions, Guwahati and Khulna both built increasingly disconnected streets over time, while Manama built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Notably, Guwahati had a more sprawly network than Khulna in 1975 but the two have since reversed their relative ranking.
