BizerteMannargudiMan

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