In new street additions, Birma built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Khalifa City built increasingly connected streets over time and Una fluctuated in its street-construction patterns. For the full network, Birma became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Khalifa City became progressively more connected and Una became progressively more disconnected. Notably, Birma had a more connected network than Khalifa City in 1975 but the two have since reversed their relative ranking.
