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