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