Fords

Fords are known as "Badenes" and are quite common in the northern part of Cuyo and the Northern Region.

There are many dry river beds that run across the highway's alignment, draining the Andean foothills that lie to the west. They only carry water during the summer rainy season, and building bridges to cross them would be an expense. Furthermore, the summer flash floods wash mud, branches and rocks down from the mountains which would quickly clog the area beneath the bridges, damming the rivers.

After a downpour, the road is quickly cleared with road grader that moves the mud ⁄ rock slides and opens the highway to traffic.

Don't attempt to drive across a flooded ford, wait for the water level to drop.
