Used by the Maya for travel and transporting goods, the causeways were identified in the Mirador Basin, which lies in the far northern Petén region of Guatemala, within the largest tract of virgin tropical forest remaining in Central America.
Also known as the Kan Kingdom, El Mirador is considered the cradle of Mayan civilization. Prior to its abandonment in 150 A.D., it was the largest city-state in the world both in size 833 square miles and population. It boasted the largest known pyramid in Central America, and was home to at least one million people.
Researchers have known about the presence of these roads since 1967, when British Mayanist Ian Graham published a map of Mirador showing causeways crossing the swamp regions. Now laser-based remote sensing has been used to map the area, providing new insights into the massive system of superhighways.
The Light Detection and Ranging tool, known as LiDAR, is capable of penetrating the thick jungle vegetation at a rate of 560,000 dots per second, producing detailed images that mimic a 3-D view of the scanned areas.

"These causeways are 130 feet wide, up to 20 feet high and in some cases they extend as far as 25 miles," Hansen said.
The first building of the causeway between Mirador and Tindall and Mirador and Nakbe dates to 600 and 400 B.C., while other causeways date from 300 BC to 100 A.D.
