In new street additions, Zheba fluctuated in its street-construction patterns, while Nimule built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Lishui built increasingly disconnected streets over time. For the full network, Zheba grew more disconnected from 1975 through 1976-1990, then improved, while Nimule became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Lishui became progressively more disconnected. Zheba and Nimule have been converging in their street-network character since 1975.
