Phases

Miami
Miami River to SW 13th Street (Coral Way)

About Phase 1: 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 will run from the Miami River to Coral Way, encompassing the northernmost portion of The Underline.

The design for the Brickell Backyard by James Corner 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.

Feature areas:
The River Room, offers a unique vantage point to views of the Miami River and includes butterfly gardens and a dog-friendly area, and much needed meditative, open, green space for residents and their pets (between Miami River and SW 7th St)
The Urban Gym, an active recreation space sponsored by Baptist Health South Florida with flex court for basketball and mini-pitch soccer sponsored by Swire Properties has spectator seating and areas for strength training and stretching, and spaces for group classes. A running track wraps around the Urban Gym with a 14-foot fence (between SW 7th and SW 8th Street)
The Promenade, a public walkway with pedestrian and bicycle dedicated paths punctuated by a series of rooms that promote social interaction (between SW 8th St and SW 10th St/Brickell Metrorail Station)
● Game room with individual tables for chess, checkers and dominoes lines the area along the east side of SW 1st Court.
● Dining room featuring 50-foot long communal table seats up to 50 people faces SW 1st Avenue.
● Sound stage plaza sponsored by Florida Power & Light provides comfortable places to gather for community events and programs or a space to watch the activity on The Underline.
The Oolite Room, a lush naturalized area featuring four butterfly gardens with seating of oolite boulders surround the dedicated bicycle and pedestrian paths, which run between the existing large oolite stone formations and directly beneath the Metrorail. (between SW 12th St and SW 13th St)

Goals and Priorities: Phase 2 is built on three key drivers: safe multi-modal transportation, nature, and community. Safety: safe biking and walking paths, lighting and improved crosswalks; Nature: native vegetation including trees, plants and grasses that support The Underline master plan for landscaping with a focus on pollinators supporting birds, bees and butterflies. Part of pre-construction efforts include soil remediation and botanical tree tagging for existing healthy trees.

Features: Phase 1 features numerous amenity areas that connect to the Brickell Metrorail and Metromover stations with numerous free community programs. Plus green infrastructure and below ground drainage that will help with stormwater flooding and runoff. Other notable project components include:
– The addition of 30,000 native plants and trees.
– (Canopy removed: 195,858 square feet, Canopy replaced: 266,700 square feet)
– Resting and seating areas along the paths with oolitic limestone boulders and seat walls.
– Hydration stations at the amenities.
– Bike repair station at the Urban gym
– Bike racks throughout.
– Dog friendly with doggie bag dispensers throughout.
– Trash and recycling receptacles throughout the corridor.
– LED lighting
– Free WiFi service at the Vizcaya and Simpson Park Playground areas.
– Public art
– Programmable areas for numerous public events, cultural, educational and health and wellness programs.

About Phase 2: Phase 2 of The Underline is a 2.14-mile segment that connects SW 13th St. to SW 19th Ave. Construction began Fall 2021 and is expected to be completed in the summer of 2023.

Goals and Priorities: Phase 2 is built on three key drivers: safe multi-modal transportation, nature, and community. After many presentations, public meetings, surveys, and community feedback, two of the main public priorities are: Safety: safe biking and walking paths, lighting and improved crosswalks; Nature: native vegetation including trees, plants and grasses that support The Underline master plan restoration of the Pine Rockland, Hardwood Hammock, Pollinator and Wet Prairie ecosystems. Part of pre-construction efforts include the removal and relocation of trees along the Phase 2 segment. In preparation for this work, informational tags with QR codes are on trees that are being relocated and removed. Trees that are remaining are protected by orange fencing
