The western part of the beltway (between Acceso Oeste and Acceso Norte) opened in 1982.

The remainder of the beltway was started under the Kirchner government in 2011 as the 'Autopista Presidente Perón'. The project was continued under the Macri government, but was renamed the 'Camino Parque del Buen Ayre'. It seems that the name has now been reverted to Perón again.

The 7 kilometer segment between Virrey del Pino and Tristán Suárez has recently opened to traffic: 18 October 2021: https://elnacionaldematanza.com.ar/2021/10/20/virrey-del-pino-habilitaron-un-tramo-de-la-autopista-peron/

A beautiful new freeway in 2021 ... without hard shoulders?!

I bump this thread with that GSV of Highway-40, where the landscape have some more or less similarities with Route 66 in the west.
