In new street additions, Cili fluctuated in its street-construction patterns, while Mazatenango built increasingly disconnected streets over time and Numan 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, Cili had a more sprawly network than Mazatenango in 1975 but the two have since reversed their relative ranking.
