LaredoPoza RicaTanga

In new street additions, Laredo built increasingly disconnected streets over time, while Poza Rica fluctuated in its street-construction patterns and Tanga built increasingly disconnected streets from 1975 through 1991-2005, then improved. For the full street network, though, all three cities follow the same trend. Laredo and Poza Rica have been growing further apart in their street-network character since 1975.
