Why you should experience The Underline in Miami, Florida.
The Underline is an innovative linear park where Brickell's contemporary urbanism, multimodal transportation, landscape architecture, and community life transform forgotten infrastructure into one of America's most ambitious public spaces.
Set along South Miami Avenue beneath the Metrorail corridor near Brickell Metrorail Station and just steps from Simpson Park, this vibrant greenway weaves together shaded walking paths, protected cycling lanes, native landscapes, public art, fitness areas, gathering spaces, and cultural programming beneath nearly ten miles of elevated rail infrastructure. Carefully designed gardens, sustainable stormwater features, and flexible civic spaces create a dynamic environment that reconnects neighborhoods while encouraging active transportation and year-round public life. Every section demonstrates how visionary planning can reshape overlooked urban infrastructure into a thriving civic destination. The result is an urban experience defined by innovative design, environmental resilience, and one of the nation's most influential linear parks.
What you should know about The Underline.
The Underline is best known for transforming the 10-mile corridor beneath Miami's elevated Metrorail into a destination-scale linear park inspired by New York's High Line but distinguished by its integration of transportation, ecology, recreation, and neighborhood connectivity across seven Miami communities from the Miami River to Dadeland South. Conceived in 2014 after founder Meg Daly recognized the untapped potential of the neglected right-of-way while recovering from a bicycle accident, the project evolved through an internationally recognized master plan led by James Corner Field Operations, the landscape architecture firm behind New York's High Line. Construction began in 2020 with the opening of Brickell Backyard, the first completed one-mile segment featuring more than 350 native plant species, bioswales, rain gardens, outdoor fitness facilities, playgrounds, public art installations, and dedicated pedestrian and cycling routes that connect directly with Miami-Dade Transit's Metrorail system. Designed to improve climate resilience alongside mobility, the landscape incorporates extensive tree canopy, habitat restoration, stormwater management infrastructure, and heat-mitigating green space while creating safer multimodal connections throughout the urban core. Upon full completion, The Underline will deliver approximately 120 acres of public parkland beneath existing transit infrastructure, establishing one of the largest adaptive infrastructure reuse projects in the United States and a global benchmark for sustainable urban placemaking.
The project demonstrates how transportation infrastructure can become the framework for ecological restoration, public health, and community building rather than functioning solely as a mobility corridor. Carefully integrated landscape architecture, resilient planting strategies, flexible gathering spaces, educational programming, and seamless transit connections continue redefining expectations for urban public space while reinforcing Miami's leadership in climate-responsive city design. The Underline stands among the world's most influential contemporary examples of infrastructure transformed into civic landscape.
