Our vision is to transform the underutilized land below Miami’s MetroRail, from the Miami River to Dadeland South Station, into a 10-mile iconic linear park, world-class urban trail and living art destination.
The Underline will connect communities, improve pedestrian and bicyclist safety, create over a hundred acres of open space with restored natural habitats, encourage a healthy lifestyle, provide an easily accessible place to exercise, create a mobility corridor that integrates transit, car, biking and walking, provide a 10-mile canvas for artistic expression, attract development along US1, and generate significant economic impact.

The 10-mile Underline will be Miami-Dade County’s first mobility corridor integrating all modes of transit. The Underline will connect to downtown and the Miami River Greenway on the north and to the proposed Ludlam Trail and the existing South Dade Trail on the south. This map shows many other proposed connections.
The Underline will be the spine of this future network of 250 miles of trails.
James Corner Field Operations
Through a competitive process, James Corner Field Operations of New York City was selected to create the master plan for The Underline 10 mile linear park and urban trail. With input collected from surveys and 6 public meetings the plan was completed in late December, 2015. We will proceed with design plans and secure funding for construction. Join now to become a Friend of The Underline so we can keep you up-to-date during the design process.
UM School of Architecture Studies
The University of Miami School of Architecture has supported the Friends of The Underline initiative with student and faculty resources. Led by Professor Rocco Ceo, a Spring 2014 studio class of ten students created concept design of the trail, park space, and intersection interventions. A Spring 2015 study was conducted with concept ideas for transit oriented development at the University of Miami and Brickell Metrorail stations.
Friends of The Underline is a 501C3 non-profit organization advocating to transform the underutilized land below Miami’s Metrorail into a 10-mile linear park, urban trail and canvas for artistic expression to create a safer, more connected, mobile, and engaged community.
We have partnered with the Miami-Dade County Parks, Recreation and Open Spaces and Transportation departments. Our board of directors and sub-committee members nclude architects, designers, urban planners, biking advocates, marketing experts, philanthropists, legal and accounting professionals, business leaders, real estate developers, and more.

Friends of The Underline founder, Meg Daly, broke both of her arms in 2013. Since she couldn't drive and had to go to physical therapy, she took Metrorail near her home and walked underneath the train tracks to her final destination. In the shade of the tracks, she wasn't that hot, even though it was July. She also noticed how wide the corridor is and that she was the only person using it. At that moment, she thought this land could be a linear park space and enhanced urban trail.
Through a competitive process, James Corner Field Operations (JCFO) was selected as the master plan design team from a field of 19 applicants. This team has been engaged to create a master plan framework and detail for two demonstration projects. The companies working in collaboration with JCFO include Fairchild Tropical Botanic Garden, Kimley-Horn, HR&A Advisors, HLB Lighting, and Pentagram.
Future construction documents, construction and project management will also require professional teams. Click here to see the master plan.
The master plan provides standards and requirements for the urban trails including trail widths and proposed materials. It also includes recommendations for lighting and wayfinding, seating, amenities, etc. The plan proposes improvements to crosswalks, intersections. Landscape recommendations include a plant palette and placement. There are also proposals for destination parks.
The master plan includes an economic impact study and project cost based on the master plan design. Click here to see the master plan.
The May 2007 MPO Metrorail M-Path master plan by Kimley-Horn, the Miami-Dade County Parks, Recreation and Open Spaces master plan, MDT's M-Path improvements (ongoing), the University Station Bicycle/Pedestrian overpass and the ThinkBike 2015 report.
On the north end, The Underline begins at the Miami River north of the Brickell Metrorail station. On the south end, The Underline will end at Dadeland South Metrorail station.
The University of Miami School of Architecture generously offered university resources for conceptual planning for the initiative. All of the student work, which was pro bono, has been provided to the master plan design team.
We cannot plan for permanent structures underneath Transit's guideway per FTA requirements.
The total cost is $110-$120 million which includes:
$80 Million for the two trails, lighting, seating, and other amenities
$20 Million for intersection improvements (over 30 intersections)
$20 Million for destination parks.
Please see the complete study here. Highlights are:
Residential real estate appreciation - properties directly abutting the 10-mile corridor will see up to a 25% increase in value. Properties as far away as 1/3rd mile will see a up to a 5% increase in value for a total $300-$485 Million in increased taxable value and $120-$200 Million in new tax revenue over 20 years.
New development - There is currently $3 Billion in planned new development near the corridor which will create $150 Million incremental assessed value and $60 Million in new tax revenue over 20 years.
Job creation - 1,000 new jobs from construction and 400 jobs annually.
Economic activity - $170 Million in total economic output during construction and $50 Million in annually after completion.
Projects with similar vision and scope have taken a decade to complete. You can help us build it in less time by supporting the initiative and donating to the cause at www.theunderline.org
We are fully funded for our master planning. Funders include 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 the Mitchell Wolfson Foundation.
For construction, we have raised:
$3 Million in Miami-Dade County road impact fees
$1 Million in City of Miami park impact fees from District 2
$1 Million FDOT TAP Grant awarded to Miami Dade Parks & Recreation
Future funding will be from public and private sources. Trail and intersection components will be supported by public parks, destination parks will be supported with private sources.
The Indianapolis Cultural Trail - 8 miles in downtown Indianapolis, 30 feet wide, $8 Million/Mile. The Atlanta Beltline - 22 mile loop around Atlanta, 6 miles completed, current trail under construction is $14 Million/Mile. The Chicago 606 - Elevated trail (abandoned rail corridor 30 feet wide), 3 miles long + ground level parks - $35 Million/Mile.
A free bike club to show that biking is a fun, safe and a healthy way to enjoy our cities. We will have group bike rides the first Sunday of the month for cyclists of all levels to explore the future Underline and its surrounding neighborhoods and attractions by bike. Registration for each bike ride will be on Eventbrite.
All monthly bike rides are free and open to the community. We would appreciate donations (see theunderline.org/donate) of any amount to support our free-to-the-public biking club.
Please arrive at the published start time. Make sure your bike is in working order. Bring water, a bike helmet and some cash in case you want to buy something along the way. Riders must be 12 years or older. All riders will be required to sign a liability waiver.
User safety is one of our biggest concerns. Currently the MPath, the bike path underneath MetroRail, has limited lighting or amenities, and needs wider and safer crosswalks. All of these, and other safety issues, are being addressed.

We used the 10 mile length of the corridor (52,800 feet) multiplied by 100 feet (average width of the corridor as determined by Miami Dade County Transit) is 121.21 acres. This is an estimate of the entire corridor including intersections. Since transit stations, parking, and other facilities encroach the corridor, we are using "100 hundred acres" as a working number until validated by the master plan and future surveys.
Please visit our "News" section on this website. Both the results of the public meetings and survey are posted.
Friends of The Underline are advocating for the transformation of the land below Metrorail from the Miami River to Dadeland South. The Friends group is working with County agencies (both Miami Dade Parks and Transportation departments) to raise government grants, including county, state and federal while the Friends group works to secure municipal and private funding. The management and programming of The Underline will be run by a public 501C3 represented by the County, FDOT, FTA (Federal Transit Authority), Friends of The Underline and three municipalities.
The Underline will be built by Miami-Dade County Parks Department. Management, maintenance and programming will be done by a public 501C3 (see previous question.)
The Underline is built on public land and we must follow best practices based on County policy. The private sector has proven to be able to activate, mobilize and champion individual projects, for example our own Arsht Center and nationally, many park conservancies including Central Park Conservancy
The Brickell area has the most density, the least amount of green space and will be a very visible demonstration to the community to propel demand for the remaining phases to be funded and built. The Underline is being built in phases based on funding and to provide the least amount of impact to users of the existing path.
The area underneath The Metrorail from the Miami River to Dadeland South (the footprint for The Underline) has one owner and is contiguous. Once over the river, the area under Metrorail is much more complicated because of land ownership, rights of ways, etc. We are mapping how to get over the river, and connect to north, west and east access points once The Underline is built.
The existing path is not lit, meanders, which provide poor visibility and has many unsafe conditions. The Underline is not am improvement of the existing corridor, it is a transformation with 2 straightened, widened trails, lighting and many amenities, and native vegetation.
We will be adding vegetation to absorb and dampen traffic noise. However, this is an urban trail in a dense area and there will always be noise.
We are not contemplating bathrooms at this time. The Underline is contiguous to many commercial establishments that provide easily accessible public bathrooms
We would like have WIFI.
Yes, as they do now. We have coordinated closely with Miami-Dade Transit to accommodate their maintenance and service access requirements.
Art will be selected and determined by Miami-Dade County Art in Public Places Friends of The Underline Art Advisory and is not designed at this time. As an ArtPlace Americas grantee, we are currently studying 4 temporary installations that will engage and activate the community.
Friends of the Underline is a 501C3 non-profit organization. Your donations are tax-deductible and will be used to help us advocate and promote The Underline and administrate our organization. We really appreciate your support.
