Project: SR 826 (Palmetto Expressway) / SR 836 (Dolphin Expressway) Interchange Improvements – Section 5 Design-Build
Client: FDOT District 6
Cost: $559 Million
Location: Miami-Dade, Florida
Description: In the heart of Miami-Dade County, this $580 million-dollar design-build project, known as Palmetto Section 5, consisted of the reconstruction of one of the busiest interchanges in Florida. With over 500,000 vehicles traversing the facility on a daily basis, it took skilled coordination and oversight to build this four-level system-to-system interchange consisting of 47 bridges, including four segmental directional flyover ramps. The launching gantries became a symbol of this great project and of the ingenuity of our team allows us to build the project without shutting down the facility.
Project Features: This project was the last and largest section of the Palmetto Expressway Improvement Program (Divided into 12 Sections). The primary objective of the project was to increase capacity along the Palmetto Expressway (SR 826) and the Dolphin Expressway (SR 836) while enhancing existing ramp connections and creating connections that did not exist before. The project also made provisions for express lanes connections for future projects. Design innovations, coupled with a well-executed construction plan, allowed for an early completion of the project while providing FDOT $276 million in savings over the Department’s construction estimate.
BCC Engineering was the Lead Designer responsible for managing the design team. BCC developed the roadway geometry and final plans, led the structures concept design for the 47 bridges, and provided final design for 22 bridges.
