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