KalarNan'anCa Mau

In new street additions, Kalar built increasingly disconnected streets over time, while Nan'an fluctuated in its street-construction patterns and Cà Mau built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Notably, Kalar had a more sprawly network than Nan'an in 1975 but the two have since reversed their relative ranking.
