MangSan Antonio del TachiraTaiping

In new street additions, Mang fluctuated in its street-construction patterns, while San Antonio del Táchira built increasingly disconnected streets from 1975 through 1976-1990, then improved and Taiping built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Mang and San Antonio del Táchira have been growing further apart in their street-network character since 1975.
