Activity has been spotted at the site of the Miami Riverwalk Towers mega development, a 4.2 million-square-foot multi-building mixed-used project planned for the western perimeters of Brickell, Miami. Designed by Kobi Karp and developed by CG Miami River LLC, lead by New York City’s Meyer Chetrit, the development is projected to yield 1,678 residential units, 330 hotel rooms, nearly 197,000 square feet of retail space, and just over 98,000 square feet of office space. The first of four towers may soon go vertical at 275 Southwest 6th Street, the northwestern section of the site, and rise 54 stories topping out at 643-feet.
