Provo in context: Street-network sprawl trends

The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Provo plotted against Utah and United States. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Provo's incremental SNDi fell from 4.14 to 3.94 between 1991-2005 and 2006-2020. In terms of the aggregate network, Provo ranked 4th out of 6 cities in Utah and 201st out of 333 in United States as of 2020.

Rankings go from most connected to most disconnected — rank 1 is the most connected.

In new street additions, Provo built increasingly disconnected streets from 1975 through 1991-2005, then improved, while Lokoja built increasingly disconnected streets over time and Qingzhou built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Provo and Lokoja both became progressively more disconnected, while Qingzhou became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards. Provo and Lokoja have been growing further apart in their street-network character since 1975.
