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