In new street additions, Milton Keynes and Quiha both built increasingly disconnected streets over time, while Rehovot fluctuated in its street-construction patterns. For the full street network, though, all three cities follow the same trend. Notably, Milton Keynes had a more sprawly network than Quiha in 1975 but the two have since reversed their relative ranking.
