In new street additions, Bambey and Mopti both built increasingly disconnected streets over time, while Ohmi-Hachiman 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, Bambey had a more connected network than Ohmi-Hachiman in 1975 but the two have since reversed their relative ranking.
