While Machilipatnam and Beni Mazar both built increasingly disconnected streets from 1975 through 1991-2005, then improved, Trieste fluctuated in its street-construction patterns in new street additions. For the full network, Trieste and Machilipatnam both became progressively more disconnected, while Beni Mazar grew more disconnected from 1975 through 1991-2005, then improved. Notably, Trieste had a more sprawly network than Beni Mazar in 1975 but the two have since reversed their relative ranking.
