The chart above shows the evolution of street network disconnectedness of the most connected and most disconnected cities in Ghana, for both new street additions (left) and the aggregate street network (right).
Ghana in context: Street-network sprawl of new development
The level of street-network sprawl in new development in Ghana followed a zig-zag trend with an overall increase. To get a sense of how street development has changed in Ghana, we can consider three of its most populous regions: Greater Accra, Ashanti and Eastern. Out of the three regions, Ashanti and Eastern do not follow the same trend as the country. The level of street-network sprawl in new development in Ashanti rose steadily. The level of street-network sprawl in new development in Eastern rose steadily.
How do development practices in Ghana fare in comparison to others in the world? Most recently in 2006-2020, street construction in Ghana was the 113th-most disconnected out of the 179 countries in the world. Its position in the ranks since 1975 has risen; relative to other countries in the world, street construction in Ghana has become more disconnected. Ghana ranked 117th in 1975, 101st in 1976-1990, 87th in 1991-2005 and 113th in 2006-2020.

Taking into account the entire (i.e. aggregate) street network in Accra as of 2020, the overall level of street-network sprawl is 3.5, which is relatively sprawly. The level of street-network sprawl in new development in Accra followed a zig-zag trend with an overall increase.
Ghana in context: Aggregate street-network sprawl
As of 2020, the city with the most disconnected street network in Ghana is Nkwanta with an SNDi of 10.2, which is very sprawly. Conversely, the most connected city is Gushiegu with an SNDi of 1.03, which is very well-connected. See these two cities’ trends in the above graph, or dive deeper into each: Gushiegu, Nkwanta.
The level of street-network sprawl in the aggregate network in Ghana rose steadily. To get a sense of how the aggregate street network has changed in Ghana, we can consider three of its most populous regions: Greater Accra, Ashanti and Eastern. Out of the three regions, Greater Accra does not follow the same trend as the country. The level of street-network sprawl in the aggregate network in Greater Accra followed a zig-zag trend with an overall increase.
To date, Ghana is the 119th-most disconnected out of the 179 countries in the world.
