In new street additions, Peabody built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Nakhon Sawan fluctuated in its street-construction patterns and Longshan built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns. For the full network, Peabody and Nakhon Sawan both became progressively more disconnected, while Longshan became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Notably, Peabody had a more connected network than Longshan in 1975 but the two have since reversed their relative ranking.
