Friends of The Underline completed and opened the 10-mile Kenneth C. Griffin Urban Trail from Brickell to Dadeland Mall, with a ribbon-cutting ceremony held Thursday morning. The trail is open to the public.
Why it matters
The trail turns land beneath the Metrorail into a continuous route for walking and biking in Miami-Dade County, a place described as one of the most dangerous in the United States for those activities. Residents gain a long, car-free corridor connecting two major Miami-area hubs.
The completed segment spans 10 miles, a project that took 12 years and cost roughly $150 million across federal, local and private philanthropic partners. Several additional parks along The Underline are still under construction, with completion expected by February 2027.
The players
The Underline
A Miami urban park and trail project built along the Metrorail corridor, developed by the nonprofit Friends of The Underline.
Chapman Partnership
A Miami-based nonprofit that provides services to people experiencing homelessness and partners on the Park Stewards Program.
Lennar Foundation
The philanthropic arm of the homebuilder Lennar Corporation, which funds community and development initiatives in South Florida.
The details
The project converted land below the Metrorail into a park and trail after Meg Daly proposed the idea following a bike accident. The Park Stewards Program, a partnership between Chapman Partnership, the Lennar Foundation and The Underline, trains people experiencing homelessness and pays them a living wage to work on the trail.
Timeline
Thursday morning: ribbon-cutting ceremony commemorates completion of the 10-mile trail.
February 2027: expected completion of the remaining Underline parks.
Trail Corridor
Like New York's High Line, which turned an unused elevated freight line into a park, The Underline reuses transit-adjacent land for public recreation. Its 10-mile route places it among the longer urban trail projects built inside a major American metro area.
Residents can now walk or bike the full 10-mile stretch from Brickell to Dadeland Mall without sharing roads with traffic. The trail gives a car-free option for commuting and recreation along the Metrorail corridor.
The takeaway
Shared transit corridors can be reclaimed as public recreation space, and Miami's new trail shows how a long-running project can deliver connected routes for everyday walking and biking.
What happens next
The remaining Underline parks are expected to be completed by February 2027.
