Palmetto Express Lanes
Project Description: The Florida Department of Transportation (FDOT) District Six (Miami–Dade County) and FDOT District Four (Broward County) worked together to implement express lanes along 28 miles of the SR 826/Palmetto Expressway and I–75 corridors from just south of SR 836/Dolphin Expressway in Miami–Dade County to I–595 in Broward County. FDOT is currently evaluating non–Express Lanes alternatives for the SR 826 South segment as well as preparing to implement Express Lane modifications on SR 826 from Flagler Street to NW 154 Street segment.
In a collaborative effort, both districts will jointly manage the procurement, design, and construction of the following additional segments:
– US 1 to West Flagler
– NW 154th Street to Golden Glades Interchange (GGI)
FDOT District 6 is implementing the I–75/Palmetto Express Lanes Project (Palmetto Express) in Miami–Dade County which extends approximately 10 miles along the Palmetto Expressway from West Flagler Street to NW 154 Street, and approximately three (3) miles along I–75 from the Palmetto Expressway to NW 170 Street. For additional information on the I–75/Palmetto Express project in Miami–Dade County, please contact Marta.Rodriguez@dot.state.fl.us.
FDOT District 4 was responsible for the five (5) project segments from I–595 south to NW 170 Street (15 miles).
