In new street additions, Tulsipur built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Maniar built increasingly disconnected streets over time and Sirius built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Tulsipur became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Maniar became progressively more disconnected and Sirius grew more disconnected from 1975 through 1991-2005, then improved. Notably, Tulsipur had a more sprawly network than Sirius in 1975 but the two have since reversed their relative ranking.
