In new street additions, Coventry and Memphis both built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Tangail built increasingly disconnected streets over time. For the full street network, though, all three cities follow the same trend. Notably, Coventry had a more sprawly network than Tangail in 1975 but the two have since reversed their relative ranking.
