A massive aerial Lidar survey in the Petén Basin has revealed a sprawling 2,000-year-old road network that linked over 50 Maya urban centers during the Preclassic period. These elevated limestone causeways, known as sacbeob, extend for hundreds of miles through what is now dense, impenetrable jungle. The scale of the network suggests a much higher degree of political and economic integration among the early Maya than previously thought, functioning as a 'sacred infrastructure' for pilgrimage and trade.
The survey also identified thousands of hidden structures, including defensive ramparts and sophisticated water reservoirs, built along the road arteries. Archaeologists noted that the roads were not merely functional but were built to align with specific celestial events, reinforcing the divine authority of the rulers who commissioned them. This discovery is being called a 'game-changer' for understanding the early development of Maya statehood and urban planning.
