In new street additions, Sujapur built increasingly disconnected streets over time, while Malumghat Bazar built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Biyahmu built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Sujapur and Biyahmu both became progressively more disconnected, while Malumghat Bazar became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Sujapur and Malumghat Bazar have been converging in their street-network character since 1975.
