The SR 826 / SR 836 Interchange is the second largest highway project in Florida. It is a four level interchange in the heart of Miami-Dade County adjacent to the Miami International Airport and includes reconstruction of approximately 2 miles of SR 826 and 3 miles of SR 836 to provide 5 lanes in each direction. The project also includes the introduction of EBCD and WBCD roads along SR 836, as well as the construction of 47 new bridges, including 4 segmental bridges.
