The Arroyo Colorado is a river in Uruguay .
It rises in the eastern part of the city of Las Piedras . From there it flows, while it forms the border between Las Piedras and Progreso , first in a north-westerly direction, before its course bends southwest from the confluence of its right-hand tributary Arroyo Colorado Chico . At Paso Don Fabián , it crosses under Ruta 48 and a few hundred meters downstream also Ruta 36 . On its last section from the confluence of the Arroyo de las Piedras it forms the border of the departments Canelones and Montevideo , and then flows into the Río Santa Lucía on the left.
