Miami’s Metrorail transit system, the majority of which runs above ground, stretches 24 miles from south to north in the city, mostly alongside U.S. 1 along the south end. But the areas underneath the metro’s two lines, covered in dirt, grass, and asphalt, are mostly unused by residents.
Now the city is turning 10 miles of space beneath to Metrorail into a new park and pedestrian path that will connect South Miami, Coral Gables, and downtown Miami.
The Underline was designed by New York City-based firm James Corner Field Operations, which envisioned Manhattan’s famed elevated park, the High Line.
The design follows the rising trend of urban projects, like the Wabash Lights in Chicago and the Burnside Skatepark in Portland, that have turned underpasses into public parks.
The plan calls for two parallel paths. One path for cyclists will be 10 feet wide and another for pedestrians will be eight feet wide.
Along the way, the Underline will feature a playground, picnic areas, as well as an outdoor fitness area. There will also be art and events programming open to the public in a few of the larger park spaces. The path will be built underneath six metro stations, which Underline users will be able to access by stairs.
The goal of the project is to transform the underutilized land below the Metrorail, and provide more car-free space for Miami residents to gather, walk, play, and bike.
Construction is underway and should wrap up by 2020.
