In new street additions, Tala built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Bà Rịa built increasingly disconnected streets from 1975 through 1976-1990, then improved and Waingapu built increasingly disconnected streets over time. Looking at the full network, Bà Rịa and Waingapu both became progressively more disconnected, while Tala became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Tala had a more sprawly network than Waingapu in 1975 but the two have since reversed their relative ranking.
