Miami’s Underline project is turning over 120 acres beneath elevated rail lines into a vibrant, 10-mile linear park that blends walking and cycling paths with native habitat restoration and community spaces.
- Transforms 120 acres beneath Metrorail into park and trail
- Connects eight metro stations and multiple neighborhoods
- Supports native habitats, flood control, and community use
What happened
The Underline Miami is an innovative project transforming the space beneath the city’s elevated Metrorail tracks into a long, continuous green corridor. Spanning 10 miles and 120 acres, this linear park and trail weaves through multiple neighborhoods from downtown Miami to the Dadeland South station. It combines walking and cycling paths with nature restoration and public gathering areas, turning previously overlooked infrastructure into a valuable community asset.
The project includes native plantings, thousands of trees, and rain gardens to support biodiversity and improve urban resilience against flooding. It links eight Metrorail stations and is designed for both transportation and recreation, encouraging residents to opt for walking or biking over driving. Community input has shaped the project to ensure it serves local needs and becomes an inclusive public space.
Why it feels good
The Underline offers a refreshing reimagination of urban space in a city known for dense development, congestion, and heat. By combining nature, mobility, and community into one corridor, it improves air quality, provides shade, and creates vital habitat for pollinators and birds. This greenery helps moderate Miami’s intense heat and addresses flooding concerns with natural stormwater management solutions.
Beyond environmental benefits, the trail creates inviting spaces for exercise, play, and social connection, fostering a strong sense of community. The multipurpose design encourages sustainable transportation choices, which lowers emissions and reduces traffic pressures. Seeing underused land repurposed in such a vibrant, inclusive way inspires optimism for urban living and ecological coexistence.
What to enjoy or watch next
Already popular areas like the Brickell Backyard showcase how underutilized urban spaces can become lively, welcoming destinations. As construction progresses, the full 10-mile corridor will provide tens of thousands of Miami residents with easy access to green space within a 10-minute walk. Upcoming phases will expand the network and introduce new amenities, art installations, and community programming.
Visitors and locals can look forward to enjoying an accessible, safe, and beautiful path for walking, biking, and relaxing. The Underline also serves as a model for other cities looking to merge infrastructure, nature, and neighborhood connectivity. Watching this project finish and thrive will be a pleasure for those who value vibrant urban living and sustainable design.
