National Route A008 is a 30 km (18.6 mi) beltway highway for the city of Rosario, Argentina.

The road allows drivers to bypass the congested city center.

The official numbering system denotes this road as "A008" but this denomination is mostly unknown by the locals as it is still called "Avenida de Circunvalación 25 de Mayo" ("25 of May Beltway Avenue") commemorating the May Revolution of 1810.

Some sections are named after different personalities by local decree.
