Overview:
The Iron Triangle is an urban interchange primarily comprised of the intersection of SR 953/NW 42nd Avenue, SR 948/NW 36th Street, and SR 25/US 27/Okeechobee Road. The interchange also features the Greater Miami Expressway Agency (GMX) SR 112/Airport Expressway, which is one of the principal highways providing access to and from Miami International Airport (MIA) and connects to other important transportation facilities and destinations such as Interstate 95 (I-95) and Miami Beach. In addition, the ramps of the Iron Triangle interchange cross over the Miami Canal (C-6). The project traverses through the City of Miami Springs, City of Hialeah, City of Miami and Unincorporated Miami-Dade County.
What is a PD&E Study:
A PD&E Study is a step in the FDOT’s highway development process. A PD&E Study assists the FDOT in determining the location; conceptual design; and social, economic, and environmental effects of the proposed roadway improvements. During the PD&E Study process, feasible alternatives are developed for roadway improvement projects. These "Build" alternatives are evaluated based on environmental, engineering, and socioeconomic conditions; safety needs; and public input. The need for additional right-of-way for stormwater and environmental mitigation will also be evaluated during the PD&E Study phase. The "No-Build" alternative is evaluated throughout the Study process. This "No-Build" alternative leaves the existing roadways as they are, with only routine maintenance as required.
If the Study results in a "Build" alternative being selected, the project may proceed to the next phase, which is the Design Phase.
Goals:
The purpose of this project is to address operational deficiencies and improve capacity, relieve existing congestion and accommodate projected transportation demand within the Iron Triangle interchange area, specifically as it relates to SR 953/NW 42nd Avenue, SR 948/NW 36th Street, and SR 25/US 27/Okeechobee Road. Other goals of the project include improving safety conditions and enhancing modal interrelationships. The need for this project is based on the following criteria:
CAPACITY/TRANSPORTATION DEMAND:Improve traffic operations/capacity, alleviate existing congestion, and accommodate projected transportation demand.
SAFETY:Improve safety conditions
MODAL INTERRELATIONSHIPS:Enhance multimodal activity
- Miami International Airport (MIA)
- Intercity and long-distance transit access
- Freight movement
- Pedestrian accommodations
Schedule:
This PD&E Study started in June 2023 and is expected to be completed by 2025. The design phase begins once the PD&E Study is complete.
FDOT Partners with Public in Study:
FDOT has developed a public involvement program as part of this PD&E Study. The public involvement process is designed to ensure public and all stakeholder input in the development of project alternatives by actively encouraging and facilitating the involvement of the general public, citizens, interested groups, elected and appointed officials, environmental resource agencies, and other key stakeholders. There will be continuous community outreach and stakeholder coordination throughout the Study process emphasizing representation of all the different communities that both live near and/or on this corridor. Small group meetings will be held as required as well.
The environmental review, consultation, and other actions required by applicable federal environmental laws for this project are being, or have been, carried-out by FDOT pursuant to 23 U.S.C. § 327 and a Memorandum of Understanding dated May 26, 2022, and executed by the Federal Highway Administration (FHWA) and FDOT.
