In new street additions, Shambu fluctuated in its street-construction patterns, while Napier fluctuated in its street-construction patterns and Mililani built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Shambu and Mililani both became progressively more disconnected, while Napier became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Shambu and Napier have been converging in their street-network character since 1975.
