In new street additions, Sénou fluctuated in its street-construction patterns, while Tindivanam built increasingly disconnected streets from 1975 through 1991-2005, then improved and Lincang built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Sénou and Tindivanam have been growing further apart in their street-network character since 1975.
