Soon, the long-neglected Minhocão viaduct in São Paulo, Brazil, will be overflowing with oxygenating plants. This is because Franco-Brazilian firm Triptyque Architecture has an ambitious plan to convert the undersection into an appealing public space covered in suspended vines.

The architecture firm is partnering with landscape architecture Guil Blanche to hang vines over three kilometers of the elevated section. Reportedly, the green installation will filter 20 percent of CO2 emissions.

As Inhabitat reports, the Minhocão viaduct was built in 1971 when the city was in a period of rapid growth. Over the years, however, pollution and noise from never-ending traffic have resulted in the elevated highway becoming more of an annoyance than a blessing.

The firm first asked members of the community for input then later decided to transform the neglected area into a section that is both welcoming and beneficial for the environment. When the area is restored and overflowing with greenery, it is expected to become a popular hangout for tourists and locals alike. Most importantly, perhaps, it will help reduce the amount of carbon emissions in the air.

All plants were specifically chosen for their air-cleaning qualities. In fact, some are recommended by NASA to clean the air. Architects intend to open the covered area as much as possible to allow for plenty of natural light. This, in turn, will ensure the ultra-green design is well cared for and the greenery thrives. Water vaporization will also be used to clean surface areas.

Already, locals and city officials are planning to host community events and cultural programs in the soon-to-be vivacious area. The new Marquise, specifically, has designated four blocks (marked off by pillars) that will house distinct programs, including food, services, culture, and shops.
