Birgunj in context: Street-network sprawl trends
Birgunj in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Birgunj plotted against Central and Nepal. All three follow the same trend in new construction, suggesting a shared regional pattern of development. Most recently, Birgunj's incremental SNDi rose from 4.31 to 4.9 between 1991-2005 and 2006-2020. In terms of the aggregate network, Birgunj ranked 5th out of 8 cities in Central and 11th out of 22 in Nepal as of 2020.

What about similarly populated cities?
In new street additions, Birgunj and Bedele both built increasingly disconnected streets over time, while Ariyalur built increasingly connected streets from 1975 through 1976-1990, then shifted to more disconnected patterns. For the full network, Birgunj and Bedele both became progressively more disconnected, while Ariyalur became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards. Notably, Birgunj had a more connected network than Ariyalur in 1975 but the two have since reversed their relative ranking.
