This project consists of replacing three existing seawalls with a new post and panel system. The project consists of replacing the existing seawalls at the following locations in the City of Miami Beach: Seawall No. 4 - Flamingo Dr. and 24th Street (± 45 LF); Seawall No. 5 - Collins Avenue at 2380 (± 280 LF); ans Seawall No. 6 - Collins Avenue at 2457 (± 144 LF). CHA completed plan development and structural design of the proposed sea wall modifications and proposed new seawalls. Drainage, roadway, and pedestrian improvements are also part of the new construction. Coordination with surveying, geotechnical, and permitting agencies are critical for the seawall improvements. The purpose of the sea wall is to increase the top of wall elevation to mitigate the effects of sea level rise.effects of sea level rise.

It also incorporated flyover bridges for left-turn movements from southbound NW 116th Place to eastbound Okeechobee Road. Additionally, two smaller bridges crossing the Miami (C-6) Canal at NW 121st Avenue and NW 116th Way were replaced and widened. The Frontage Road, from MP 6.310 to MP 8.146, underwent complete reconstruction and realignment. Beyond the structural work, the project encompassed the installation of five new traffic signals, replacement of five existing signals, and deployment of new ITS, drainage, and lighting systems. As the prime designer, CHA was responsible for all design project management and coordination efforts. They developed the roadway geometry and final plans and led the structure concept and final design for four bridges, drainage, ITS, lighting, utility coordination, and miscellaneous structures. This major reconstruction of SR 25/U.S. 27/Okeechobee Road using rigid pavement from MP 6.310 to MP 8.146 provides significant traffic operations and safety improvements for the interchange and the surrounding arterial network.

CHA was responsible for the design of all components of the project, including the demolition plan and the mitigation of existing hazardous materials. The bridge design featured a reinforced concrete deck superstructure to minimize the bridge profile. Coordination with MD-WASD, SFWMD, MDAD, and FAA was critical to ensure the requirements of all agencies were simultaneously met. The project also included lighting improvements on the bridge, a raised profile to meet canal requirements, and additional design and construction modifications to meet aviation and SFWMD requirements.
