The Evolution
of The Underline

Discover how The Underline is coming to life in three transformational phases. Each one brings new amenities, art, and infrastructure — shaping a 10-mile linear park that redefines urban space across Miami.

PHASE 01

Brickell Backyard

The first phase of The Underline opened to the public on Friday, February 26, 2021. Named the “Brickell Backyard,” this first segment of the 10-mile linear park and trail is half a mile long and runs from the Miami River to Coral Way, encompassing the northernmost portion of The Underline.

The design for the Brickell Backyard by Field Operations is organized by a procession of “rooms,” each articulated with a unique program and design intent that directly responds to its immediate context and to the needs of the local community.
