For the full network, Dengkou grew more disconnected from 1975 through 1991-2005, then improved, while Móng Cái became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards and Dhamdaha became progressively more disconnected. Dengkou and Móng Cái have been converging in their street-network character since 1975.
