United States in context: Street-network sprawl of new development
The level of street-network sprawl in new development in United States peaked in 1991-2005. To get a sense of how street development has changed in United States, we can consider three of its most populous regions: California, New York and Texas. None of the most populous cities follow the same trend as the region. The level of street-network sprawl in new development in California peaked in 1976-1990.

The level of street-network sprawl in new development in New York City followed a zig-zag trend with an overall increase.
United States in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in United States is Beechwood with an SNDi of 7.61, which is very sprawly. Conversely, the most connected city is Waco with an SNDi of 1.32, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Waco, Beechwood.
