In new street additions, Acilia and Musanze both fluctuated in its street-construction patterns, while Salerno built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Notably, Acilia had a more sprawly network than Musanze in 1975 but the two have since reversed their relative ranking.
