For the full network, Séguéla became progressively more disconnected, while Jawkatia became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Qurghontepa became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Séguéla and Jawkatia have been converging in their street-network character since 1975.
