In new street additions, Ruili built increasingly disconnected streets over time, while Mpumalanga built increasingly disconnected streets from 1975 through 1976-1990, then improved and Pubei built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Ruili became progressively more disconnected, while Mpumalanga grew more disconnected from 1975 through 1991-2005, then improved and Pubei became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Ruili and Pubei have been growing further apart in their street-network character since 1975.
