In new street additions, Liberec built increasingly disconnected streets over time, while Palmdale built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Sikandra built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full network, Liberec became progressively more disconnected, while Palmdale became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Sikandra grew more disconnected from 1975 through 1991-2005, then improved. Notably, Liberec had a more sprawly network than Sikandra in 1975 but the two have since reversed their relative ranking.
