While Silvassa and Mahishadal both built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, Guigang built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns in new street additions. For the full street network, though, all three cities follow the same trend. Guigang and Silvassa have been converging in their street-network character since 1975.
