In new street additions, Boye fluctuated in its street-construction patterns, while 禅妙村 built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Lạng Sơn built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Boye became progressively more disconnected, while 禅妙村 became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Lạng Sơn grew more disconnected from 1975 through 1991-2005, then improved.
