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