While Tierkloof and Shiren both built increasingly disconnected streets from 1975 through 1991-2005, then improved, Tunduru fluctuated in its street-construction patterns in new street additions. For the full street network, though, all three cities follow the same trend. Tunduru and Tierkloof have been converging in their street-network character since 1975.
