In new street additions, Chandipur built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Hajja built increasingly disconnected streets from 1975 through 1991-2005, then improved and Gbarnga built increasingly disconnected streets over time. For the full network, Chandipur became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards, while Hajja grew more disconnected from 1975 through 1991-2005, then improved and Gbarnga became progressively more disconnected. Notably, Chandipur had a more sprawly network than Hajja in 1975 but the two have since reversed their relative ranking.
