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