For the full network, Bayreuth and Tekkali both became progressively more disconnected, while Mananwala became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Bayreuth and Tekkali have been growing further apart in their street-network character since 1975.
