In new street additions, Al-Tabqah built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Holeta Genet fluctuated in its street-construction patterns and Le'an 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, Al-Tabqah had a more sprawly network than Holeta Genet in 1975 but the two have since reversed their relative ranking.
