In new street additions, Bilbeis fluctuated in its street-construction patterns, while Bukalasi built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Laiyang built increasingly disconnected streets over time. For the full network, Bilbeis fluctuated in connectivity, while Bukalasi became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Laiyang became progressively more disconnected. Notably, Bilbeis had a more sprawly network than Laiyang in 1975 but the two have since reversed their relative ranking.
