In new street additions, 富安镇 built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Ode-Omu built increasingly disconnected streets over time and Shaliuhe built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Ode-Omu and Shaliuhe both became progressively more disconnected, while 富安镇 became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards.
