Roads facilitate development in remote forest regions, often with detrimental consequences for ecosystems. In the Congo Basin, unpaved logging roads used by timber firms, as well as paved and unpaved public roads, have expanded greatly. Comparing older (before 2003) and newer (2003-2018) road datasets derived from LandSat imagery, we show that road networks inside logging concessions in Central Africa have doubled in length since 2003, whereas roads outside concessions increased by 40%. We estimate that 44% of all roads within concessions were abandoned by 2018, following logging operations, whereas just 12% of roads outside concessions were abandoned. Yearly deforestation rates (2000-2017) near (<1 km) roads rose dramatically during the course of this study, and were highest for older roads, lowest for
