The Underline

The Underline is a public-private partnership between the Department of Transportation and Public Works (DTPW), the Parks, Recreation and Open Spaces (PROS) Department, and Friends of the Underline.

The Underline will transform 120 acres of Miami-Dade County owned land below the existing Metrorail guideway, from the Miami River (Brickell area) to the Dadeland South Metrorail Station, into a world-class, multimodal urban trail. Once completed, The Underline will provide a walkable and bikeable corridor that will improve connectivity between surrounding neighborhoods.

The Underline will be built in eight phases. Each segment of The Underline will demonstrate Miami-Dade County’s commitment to improving and enhancing connectivity. Construction of Phase 1 - The Brickell Backyard is scheduled to start in Spring 2019.

Once all phases are completed, this project will be Miami-Dade County’s first true mobility corridor uniting all modes of transportation enhancing accessibility to eight Metrorail stations within its path and the neighboring communities. The Underline will serve 107,000 residents within a 10-minute walk, will provide access to public transportation to one University and 24 schools, two hospitals, three urgent care facilities, four major malls and over 10,000 businesses.

The 10-mile corridor, which will vary from 70 to 170 feet wide, will provide pedestrian and bicycle paths, improvements to over 30 intersections, access to public transportation, lighting and wayfinding. In addition to the transportation components, recreational features will include butterfly gardens, playgrounds, exercise equipment, basketball and volleyball courts, soccer fields, picnic areas, dog parks and more.
