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