ManausSan JoseLas Vegas

In new street additions, Manaus fluctuated in its street-construction patterns, while San José built increasingly disconnected streets over time and Las Vegas built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Manaus and San José both became progressively more disconnected, while Las Vegas became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Manaus and San José have been growing further apart in their street-network character since 1975.
