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