                         State of Acres occupation and development. However, the expansion 
                         of roads, has often been associated with the advance of 
                         deforestation, habitat fragmentation, and social conflicts. There 
                         are no up-to-date data available on the current extent of Acres 
                         road network nor its environmental and socioenvironmental impacts. 
                         In this study, we updated the State of Acres road network map for 
                         the period 2007 to 2019 through the visual interpretation of 153 
                         Landsat images (5, 7, and 8) at a scale of 1:50,000. To estimate 
                         the impact of roads, we measured the distribution of roads in 
                         municipalities and in different land tenure categories and 
                         calculated the correlation between roads and annual deforestation. 
                         Up to 2019, we estimated 19,620 km of roads, of which 92% were 
                         unofficial roads, 6% federal roads, and 2% state roads. The roads 
                         increased at an average annual rate of 590 km year\−1. The 
                         most significant advance in road length between 2007 and 2019 was 
                         in protected areas (240%), followed by public lands (68%) and 
                         settlement projects (66%). We recommend monitoring of the road 
                         network to understand the landscapes evolution and support actions 
                         against illicit environmental and socioenvironmental impacts.",
