While Lwebo and Trelew both built increasingly disconnected streets over time, Jinxi fluctuated in its street-construction patterns in new street additions. For the full network, Jinxi fluctuated in connectivity, while Lwebo became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Trelew became progressively more disconnected. Notably, Jinxi had a more connected network than Trelew in 1975 but the two have since reversed their relative ranking.
