The Underline will transform the land below Miami's Metrorail into a 10-mile linear park, urban trail and living art destination.

Friends of The Underline founder, Meg Daly, broke both of her arms in 2013. Since she could not drive and had to go to physical therapy, she took Metrorail near her home and walked underneath the train tracks to her destination. Even in July, she did not feel hot in the shade of the tracks. She also noticed how wide the corridor is and that she was the only person using it. Meg realized that the land could be utilized as a linear park and urban trail.

Through a competitive process, James Corner Field Operations (JFCO) was selected from a field of 19 applicants to be the masterplan design. This team created a masterplan framework and detail for two demonstration projects. The companies working in collaboration with JFCO include Fairchild Tropical Botanic Garden, Kimley-Horn, HR&A Advisors, HLB Lighting and Pentagram.

Friends of The Underline are transforming the land below Metrorail from the Miami River to Dadeland South. The Friends group is working with Miami-Dade County Department of Transportation & Public Works to raise county, state, federal and municipal grants. The management, maintenance and programming of The Underline will be run by a 501C3 represented by the County, FDOT, FTA (Federal Transit Authority), Friends of The Underline and three municipalities.

The area underneath the Metrorail from the Miami River to Dadeland South (the footprint for The Underline) is owned by Miami-Dade County. Once over the river, the area under Metrorail is much more complicated due to land ownership, right of ways, etc. We are mapping how to get over the river, and connect north, west and east access points once The Underline is built.

The Underline is being built in phases based on funding and to have the least amount of impact to users of the existing path.

The total cost is $110-$120 million which includes:
$80 million for the two trails, lighting, seating, native landscaping and other amenities.
$20 million for intersections improvements (over 30 intersections).
$20 million for destination parks.

Some of the funders include Miami-Dade County, the State of Florida, FDOT and the cities of Miami, Coral Gables, and South Miami and the John S. and James L. Knight Foundation, the Miami Foundation, the Health Foundation of South Florida and Mitchell Wolfson Foundation. For a better breakdown of funding by phase, please refer to our Progress page. Additional funding will derive from public and private sources.

Construction for Brickell Backyard (Phase 1, Miami River to SW 13th St.) had a groundbreaking ceremony on November 1, 2018. Phase 2 (SW 13th St. to SW 19th St.) is projected to begin design Spring 2019. To stay up to date with construction progress, please refer to our Progress page.

The MPath is an existing asphalt path below Metrorail. During construction, the MPath will be accessible but some detours might occur. The Underline will be open as each phase is completed.

Projects with similar vision and scope have taken a decade to complete. We project each phase taking a year to a year-and-a-half to complete. You can help us build it in less time by supporting the initiative and donating to the cause.

User safety is one of our biggest concerns. Currently the MPath, the bike path underneath the Metrorail, has limited lighting or amenities, and needs wider and safer crosswalks. All of these, and other safety issues, are being addressed.

The Underline will include ample lighting, patrolling security, and CC cameras along the trail.

Management, maintenance and programming will be done by a public 501C3 called The Underline Management Organization.

Along the estimated 120 acres, the linear park and urban trail will feature amenities including butterfly gardens, dog parks, exercise equipment, basketball court, mini-soccer pitch, sound stages and monumental art. To serve users of all ages, The Underline will feature numerous health and wellness, meditation, cultural, educational and environmental programming.

Plans are in the works to include WiFi along The Underline.

Bathrooms are not in the design scheme of the masterplan. The Underline is adjacent to many commercial establishments that provide easily accessible public bathrooms and are available inside Metrorail stations for riders.

One of our top priorities is getting the community involved! Please email us at info@theunderline.org with your design comments or post on our social platforms Facebook, Instagram or Twitter @theunderlinemia.
