Provincial Route 10 (La Pampa)

Its eastern end is the border with the Province of Buenos Aires at meridian 63°23'W. When crossing the FCDFS tracks in the vicinity of the city of Miguel Cané, it passes through the access to Colonia Barón. It has a cut of 5 km (3 mi) when it connects with National Route 35. It runs west again from the access to the city of Winifreda.

It is the main access road to the cities of Victorica, Telén and Santa Isabel, until its junction with National Route 143.^[2]

It resurfaces in Algarrobo del Águila to the west. It leads to the town of La Humada, ending at the border with the province of Mendoza where it continues under the name of Provincial Route 190.

From 1935 to 1979, the section between Santa Isabel and Provincial Route 11 belonged to National Route 143.^[3]
