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