In new street additions, Yuma built increasingly disconnected streets over time, while Muhanga built increasingly disconnected streets from 1975 through 1991-2005, then improved and Manzil Bourguiba built increasingly disconnected streets from 1975 through 1976-1990, then improved. For the full street network, though, all three cities follow the same trend. Notably, Yuma had a more connected network than Muhanga in 1975 but the two have since reversed their relative ranking.
