The 10-mile linear park, urban trail, and public art destination features amenities like microforests, fitness rooms, and gardens, providing a scenic and active space for residents to walk, bike, and enjoy nature. The project was spearheaded by Meg Daly, who founded the organization Friends of The Underline after breaking her arms and noticing the unused land under the Metrorail tracks. Partnered with Miami-Dade County, The Underline has become an example of repurposing unused land into a public park and community space.
