In new street additions, Sarolangun built increasingly disconnected streets over time, while Santa Clara built increasingly disconnected streets from 1975 through 1976-1990, then improved and Port Loko built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Sarolangun and Port Loko have been growing further apart in their street-network character since 1975.
