In new street additions, Attur and Nanjanagudu both built increasingly disconnected streets over time, while Petit-Goâve fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Notably, Attur had a more sprawly network than Petit-Goâve in 1975 but the two have since reversed their relative ranking.
