Ekwegbe 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 Ekwegbe plotted against Enugu and Nigeria. The SNDi of new construction in Ekwegbe was at its lowest in 1976-1990, compared to Enugu which rose steadily and Nigeria which followed a zig-zag trend with an overall increase. Most recently, Ekwegbe's incremental SNDi rose from 5.31 to 7.47 between 1991-2005 and 2006-2020. In terms of the aggregate network, Ekwegbe ranked 10th out of 11 cities in Enugu and 394th out of 422 in Nigeria as of 2020.

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

In new street additions, Ekwegbe built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns, while Tacurong built increasingly disconnected streets over time and Lawrence built increasingly disconnected streets from 1975 through 1991-2005, then improved. Looking at the full network, Tacurong and Lawrence both became progressively more disconnected, while Ekwegbe became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Ekwegbe and Tacurong have been converging in their street-network character since 1975.
