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