In new street additions, North Lakes built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Bihta built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns and Eruwa fluctuated in its street-construction patterns. For the full network, North Lakes grew more disconnected from 1975 through 1991-2005, then improved, while Bihta became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Eruwa became progressively more disconnected. North Lakes and Bihta have been converging in their street-network character since 1975.
