Day 2 · Lines — Roads to care: Bangladesh's highway network

21,564 km of national, regional and zila roads from the Roads and Highways Department, mapped by class and measured against the 2,234 hospitals mapped in OpenStreetMap (Day 1). Most mapped hospitals sit right on the highway network, but 54 upazilas, home to 11.2 million people, have both few RHD roads and no mapped hospital.
