In new street additions, Jiexi fluctuated in its street-construction patterns, while Ise built increasingly disconnected streets over time and Bhurkunda built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Jiexi grew more disconnected from 1975 through 1976-1990, then improved, while Ise became progressively more disconnected and Bhurkunda grew more disconnected from 1975 through 1991-2005, then improved. Notably, Jiexi had a more sprawly network than Ise in 1975 but the two have since reversed their relative ranking.
