Some of Miami’s biggest projects are open now. Others are years away. Citadel’s new Brickell headquarters went back to work the week of Oct. 12 after Miami-Dade approved a new safety plan, the Miami Herald reported. It is one of six projects worth following.

1. Citadel’s headquarters in Brickell

Citadel is building a 52-story office tower at 1201 Brickell Bay Drive. Site work started in March. On Sept. 14, a drill rig fell onto Brickell Bay Drive and four people were hurt. The county stopped work until it approved a safety plan on Oct. 7. Vertical construction has not started yet. Citadel told the Herald the tower will be all office space after it dropped a planned hotel.

2. The I-395 Signature Bridge

The new I-395 will cross Biscayne Boulevard under six white arches. The state lists the full project at $866 million, with completion in December 2029. It was first due in 2021. In September, crews were pouring concrete for the westbound bridge deck. The project also double-decks SR 836 and rebuilds part of I-95.

3. The Underline

The Underline is a 10-mile park and trail under Metrorail, from the Miami River to Dadeland South. Seven miles were open by August. The last stretch, through Coral Gables near the University of Miami, is expected to open by the end of 2026.

4. Miami International Airport

MIA’s building program has grown to about $12 billion. Plans include Concourse K, which adds six domestic gates in the South Terminal by 2029. A 17-gate extension of Concourse D is planned to finish in 2030. The airport’s project page lists the work.

5. PortMiami

PortMiami is already busy. It set a record with 8,564,225 cruise passengers in fiscal year 2025, the county said. It also handled more than 1 million cargo containers, measured in standard units, for the 11th year in a row.

6. Miami Freedom Park

Inter Miami played its first home game at Nu Stadium on April 4, 2026. The 26,700-seat stadium sits on a 131-acre site near the airport, on land that was once the city’s Melreese golf course. A 58-acre public park opened with the stadium. Shops and offices are still being built.

Why it matters

These projects touch daily life in different ways. The port and stadium bring visitors and jobs now. The Underline will soon give walkers and bikers one long path. The bridge and Citadel tower are still years from done, so expect detours and cranes in Brickell and Downtown for a while.
