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