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