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