In new street additions, Duri built increasingly disconnected streets over time, while Orai fluctuated in its street-construction patterns and Semey built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Notably, Duri had a more sprawly network than Orai in 1975 but the two have since reversed their relative ranking.
