BCC Engineering Merges with Heath & Lineback

This project reconstructed the existing SR 826 / SR 836 system to system interchange to a modern 4-level interchange to achieve the primary objective of increasing 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.  At its widest point the project had a total of 22 traffic lanes on SR-836.  It included reconstruction of two service interchanges.  BCC developed a concept that allowed for early completion of the project while providing FDOT $276 million in savings over the Department’s construction estimate. The concept enhanced safety and local access by utilizing CD roads and a Texas U-turn to separate freeway traffic from local and interchange traffic. The project also made provisions for future express lanes connections and future rail transit accommodations. Design innovations, coupled with a well-executed construction plan, allowed for an early completion of the project while providing.

BCC Engineering was the Lead Designer responsible for managing the large and diverse design team of 12 subconsultants. BCC developed the overall concept, roadway geometry and final plans for this national award-winning project, in addition to supervising the Structural Design, Signing & Pavement Markings Design, ITS Design, Lighting Design, Drainage Design and Environmental Permitting.

SR 826/SR 836 Palmetto & Dolphin Expressway Interchange – Section 5 Design-Build

In the heart of Miami-Dade County, this $559 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 used for bridge construction became a symbol of this great project and of the ingenuity of our team, allowing us to build the project without shutting down the facility.
