‘Amazing’ footage of this city’s highway transformation has people envious: ‘Every city needs one of these’

Keeping the planet from warming more than 2.7 degrees will require plenty of innovation.

Perhaps turning highways into gardens is just the step humanity needs to take.

Concrete is worse for the climate than flying, so Seoullo 7017 is the perfect project.

The six-year-old sky garden could provide a template for other cities to reimagine certain spaces into good-for-the-environment expanses.

The public walkway was once part of a highway and had been closed to traffic since 2006. It is now a one-kilometer (0.6-mile) greenway with 24,000 trees, shrubs, and flowers that is open 24 hours per day.

“Every city needs one of these,” one Redditor said.

Others noted many cities have one, including New York, Chicago, and Houston. Detroit, Philadelphia, and Boston are in on the trend too.
