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