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