The construction works at the Sarmiento access of the so called Obelisco Node are underway, designed by AC&A with the architecture firm Antonini Schon Zemborain and ATEC. This access to the Buenos Aires Subway System will be the second designed by AC&A and opened in recent years and will be added to the current glass-domed access to Constitución station on the C line, opened in 2015.
