In new street additions, Chaoyang fluctuated in its street-construction patterns, while Tabuk built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Naberezhnye Chelny built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Chaoyang became progressively more disconnected, while Tabuk became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Naberezhnye Chelny became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Chaoyang and Tabuk have been converging in their street-network character since 1975.
