For the full network, Pokhariya grew more disconnected from 1975 through 1976-1990, then improved, while Cascavel became progressively more disconnected and Naga became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Pokhariya and Cascavel have been converging in their street-network character since 1975.
