From I-75 to Golden Glades Interchange

The Palmetto Expressway is one of the most traveled transportation corridors in Miami-Dade County. This multi-lane expressway extends from US-1 to the Golden Glades Interchange (GGI) for a distance of approximately 25 miles. Within the project study limits, the Palmetto Expressway corridor is a six-lane divided limited access facility from I-75 to NW 27th Avenue; however, from NW 27th Ave, to the GGI, this corridor widens to an eight-lane divided expressway. From NW 67th Avenue, a one-way frontage road (NE 167th Street) runs along each side of the facility, providing access to business located along the corridor as well as Sun Life Stadium and Calder Race Track. The Palmetto Expressway provides system-level connections to I-75, Florida's Turnpike, and I-95. In addition, the Palmetto Expressway is designated as a Florida Intrastate Highway System (FIHS) and Strategic Intermodal System (SIS) facility.

The need for improvement along the Palmetto Expressway is a combination of highway safety and traffic operations deficiencies that exists along the corridor. The existing facility was designed in the early 1960s and much of its design criteria do not satisfy the current design safety standards. Many segments of the mainline facility currently operate at unacceptable levels of service during peak traffic conditions with some ramps queuing back to the mainline and in may instances impeding through traffic in the outside lane. Projections of future population and employment in the projected area indicate that travel demand will continue to increase for years to come.

The Palmetto Expressway PD&E Study will evaluate traffic capacity, operational and safety improvements for the Palmetto Expressway, which could include Active Traffic Management and Intelligent transportation System strategies, lane additions, express toll lanes, major interchange modifications, and bus rapid transit. The study will determine the number and type of travel lanes and interchange improvements required to accommodate anticipated traffic volumes and improve safety conditions throughout the project corridor. It is through this study process that various alternatives for minimizing impacts to the environment and surrounding communities will be addressed.
