For the full network, Redcliffe grew more disconnected from 1975 through 1991-2005, then improved, while Świdnica became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Maya Belwa became progressively more disconnected. Redcliffe and Świdnica have been growing further apart in their street-network character since 1975.
