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