What about similarly populated cities?
In new street additions, Woldia built increasingly disconnected streets over time, while Salamanca built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and 赵家沟 fluctuated in its street-construction patterns. For the full network, Woldia and 赵家沟 both became progressively more disconnected, while Salamanca became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Woldia and Salamanca have been growing further apart in their street-network character since 1975.
