Recent construction work on BR-156 in Southern Amapá has unearthed significant archaeological artifacts from ancient civilizations that once inhabited the area. Conducted by the National Department of Transport Infrastructure (DNIT), these excavations are part of an Archaeology Program aimed at ensuring the preservation of important archaeological sites amidst ongoing infrastructure development. The findings contribute valuable insights into the region's historical and cultural heritage.

The discovery includes decorated ceramic fragments, lithic artifacts such as axe blades, and stone flakes. These materials not only highlight the artistic and practical skills of past societies but also provide a glimpse into their social organization and economic practices. Understanding these civilizations is crucial for appreciating how they shaped the local culture and continue to influence contemporary society in Amapá.

DNIT reported that the first notable discoveries occurred in May 2025, marking a significant step in balancing modern development with the preservation of historical sites. This initiative underscores the importance of archaeological research in infrastructure projects and raises awareness about the need to protect cultural heritage even as the region progresses towards modernization.
