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