In new street additions, Kastamonu built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Ünye fluctuated in its street-construction patterns and Kondagaon built increasingly disconnected streets over time. Looking at the full network, Ünye and Kondagaon both became progressively more disconnected, while Kastamonu became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards.
