The chart above shows, for each construction period in the Eastern Equatoria region, the SNDi of new street additions (bar height) and the volume added (bar width), so that bar area reflects the total disconnectedness burden of that period's construction. The 2006-2020 period contributed the greatest disconnectedness burden, with 1,100 km of street added at an SNDi of 3.04. Overall, the SNDi of new street additions in the region followed a zig-zag trend with an overall decrease.

Effect on the aggregate network
New construction in each period adds to the total stock of streets, but does not change streets that have already been built. Therefore, it has a limited effect on the street network as a whole. The SNDis of the aggregate street network in the respective time periods are 3.29, 3.45, 3.16 and 3.17. Disconnectivity in Eastern Equatoria's street network follows a zig-zag trend. In 1991-2005, the region was most disconnected; while it was most connected in 1976-1990.
