In new street additions, Mubi built increasingly disconnected streets over time, while Bor built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns and Bukhara built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full network, Mubi became progressively more disconnected, while Bor became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Bukhara grew more disconnected from 1975 through 1991-2005, then improved. Notably, Mubi had a more connected network than Bor in 1975 but the two have since reversed their relative ranking.
