Five years. Five miles. Right on time.

The Underline, a multi-modal corridor and linear park running beneath Miami’s Metrorail, officially opened Segment 4 (SW 27th Avenue to Douglas Road) this past week, marking the completion of five continuous miles of trail within its fifth year since the project began.

The milestone represents a major step forward in transforming more than 120 acres of under-utilized land into a world-class, connected corridor that offers residents and visitors a safer, dedicated pathway for walking, biking, jogging and connecting with nature and the community.

Friends of The Underline, a nonprofit organization, commemorated the milestone with a “Five Years, Five Miles” ribbon cutting led by Miami-Dade County Mayor Daniella Levine Cava.

“This is what it looks like when infrastructure puts people first,” Mayor Levine Cava said. “The Underline is transforming under-utilized space into something that improves daily life by creating safer ways to move, more opportunities to connect, and a shared place for our community to come together. Reaching five miles in five years is a meaningful milestone for Miami-Dade County.”

With the opening of Segment 4, The Underline extends its reach into new neighborhoods, reinforcing its role as a connected mobility corridor for walking, biking and serving as an access to overhead transit.

“Projects like The Underline require clear vision, strong partnerships, and the discipline to deliver,” said Regalado, who hopes her vision for “The Shoreline” project on the Rickenbacker Causeway could connect to The Underline as well. “This milestone shows what’s possible when we invest in infrastructure that not only connects communities, but also strengthens how our county grows, moves, and plans for the future.”

Public and private partners have helped shape The Underline into a model for collaboration, where infrastructure, programming and community engagement come together to create lasting public value.

With more than 200 free programs annually, including wellness, art and music, The Underline has become a vibrant gathering place for residents and visitors alike. When complete, it will span from the Miami River in Brickell to the Dadeland South Metrorail Station in Kendall.

“The Underline offers a national blueprint and a new standard for delivering connected, multi-modal infrastructure that enhances how people move through and experience urban spaces,” said Eulois Cleckley, CEO of Friends of The Underline. “These five continuous miles have created an important mobility corridor that improves safety, expands access and strengthens connectivity across Miami’s urban core.”
