SR 826 / SR 836 Interchange Reconstruction

Close

This interchange reconstruction project, where the north-south State Route (SR) 826 (Palmetto Expressway) intersects the tolled east-west SR 836 (Dolphin Expressway) at the southwest corner of Miami International Airport, is the last component of the 12-part Palmetto Expressway Improvement Program. This program, which began construction in the mid-1990s, consisted of widening, bridge replacement, and geometric improvements along the existing 16-mile corridor extending from SR 5/US 1 in south Miami-Dade County to just north of NW 154 Street in northern Miami-Dade County. Each of the interchanges along the corridor was improved to enhance safety and traffic flow. The SR 826/SR 836 interchange handles over 430,000 vehicles daily and required reconstruction to enhance safety and reduce congestion. Major project components included: Reconstruction and widening along both SR 826 (from just north of SW 8 Street to NW 25 Street) and SR 836 (from just east of NW 87 Avenue to NW 57 Avenue) Construction of a new four-level interchange between the two expressways providing direct access in all directions Reconstruction and modification to the SR 826 interchange with Flagler Street to the south and to the SR 836 interchange with Milam Dairy Road to the east Construction of connector ramps and frontage roads for local traffic movements eliminating the need to use mainline SR 826 and SR 836 Installation of Intelligent Transportation Systems (ITS) cameras and sensors allowing for real-time traffic updates, as well as assisting in the rapid deployment of first responders and Road Rangers to clear disabled and accident vehicles from travel lanes Other connecting local street reconstruction
