Interstate 595 (I-595), also known as the Port Everglades Expressway and unsigned Florida State Road 862 (SR 862), is a 12.86-mile (20.70 km) auxiliary Interstate Highway that connects I-75 and Alligator Alley in the west with Florida's Turnpike, I-95, Fort Lauderdale–Hollywood International Airport, U.S. Highway 1 (U.S. 1), and SR A1A before terminating at Port Everglades in the east. The Interstate route was conceived in 1969 and planned as an Interstate starting in 1974. Construction began in 1984, with the expressway opening in stages in the late 1980s, with completion in 1991. The reversible tolled express lanes opened in 2014.

Close

Interstate 595 begins in Sunrise at the eastern part of the Sawgrass Interchange, with I-75 on the southern and western ends (I-75 "north" leads into Alligator Alley on the west side) and the Sawgrass Expressway (SR 869) on the northern end.^[4] From the western terminus, the highway heads east to Davie, acting as a commuter route between the western fringes of the populated part of Broward County and Fort Lauderdale. At University Drive (SR 817), I-595 goes below a partial stack interchange.^[4] Three miles east of that interchange, it meets with Florida's Turnpike and U.S. 441. The highway then continues east into Fort Lauderdale.

Continuing east into Fort Lauderdale, I-595 soon interchanges with I-95 at the Rainbow Interchange, located the northwestern edge of Fort Lauderdale–Hollywood International Airport.^[5] From there, I-595 continues east along the northern edge of the airport. It then reaches the eastern end of the airport, where it has its final interchange with U.S. 1 (which runs concurrently with SR A1A at the interchange), providing access to both the airport and Port Everglades.^[4] The eastern terminus consists of two lanes for U.S. 1 southbound, two for U.S. 1 northbound and two lanes for Port Everglades via Eller Drive. The exit for southbound U.S. 1 has a ramp to the airport.^[4] SR A1A is not listed on the exit signs.

For most of its length, Florida State Road 84 – the former route number for Alligator Alley prior to its conversion to part of the extended Interstate 75 – runs parallel to the expressway, acting as a frontage road on either side of the Interstate.^[4][5]

This section needs expansion. You can help by adding to it. (February 2010)

I-595 grew out of a expressway plan for connecting Port Everglades with Alligator Alley, first conceived in 1969 as the Port Expressway. In 1974, once I-75 was rerouted to Broward County on Alligator Alley as a part of its eastern connection from Naples, it was proposed to be built as an Interstate. When the southern terminus of I-75 was moved from Broward to Dade County at the Palmetto Expressway (SR 826)/Gratigny Parkway (SR 924) in the late 1970s, the construction of the trans-Broward expressway was delayed. However, in September 1978, the Federal Highway Administration (FHWA) officially added the eastern 4.2 miles (6.8 km) of the route to the Interstate Highway System, with the official designation of I-595.^[6]

In the early 1980s, I-595 was planned to be partially a toll expressway to cover its cost of construction. By the time construction started on July 26, 1984, the tolls for the expressway vanished, and it was built with only minor changes in its route. The first section, between I-75 and Hiatus Road opened in May 1988, with the section between Florida's Turnpike and US 1 opening on February 24, 1989, and the last section, connecting the disjointed sections opening on October 21, 1989. The expressway was designated as I-595 on June 11, 1990, and the Rainbow Interchange with I-95 was completed on March 22, 1991, the last unfinished interchange of the original plan.^[7]

The portion of the expressway between I-95 and US 1 follows the right-of-way of the Port Everglades railroad tracks that had previously run from the CSX Transportation railroad to Port Everglades.

In 2002, I-595, along with most of Florida's Interstates, switched over from a sequential exit numbering system to a mileage-based exit numbering system.^[8] Numbers were changed again^[9] at about the time the express lanes were opened in early 2014.

On April 9, 2022, Pittsburgh Steelers quarterback Dwayne Haskins was killed after being struck by a dump truck near Davie when he was attempting to cross the westbound lanes of I-595 at 6:40 am near Fort Lauderdale–Hollywood International Airport and died at the scene.^[10]

The $1.8-billion (equivalent to $2.28 billion in 2023^[11]) tolled SunPass express lanes project in the middle of the expressway to relieve the traffic congestion opened for test use on March 26, 2014, and started tolling on April 9, 2014.^[12] The express lanes will significantly improve the capacity and operations of the I-595 corridor by providing three additional at-grade lanes in the median of the corridor. The lanes will reverse direction in peak travel times (eastbound in the morning/westbound in the evening). To maximize the operational efficiency, the lanes will have tolls at varying rates throughout the day to optimize traffic flow, and access to and from the lanes will only be allowed west of 136th Avenue, east of US 441/SR 7, and through a direct connection to the median of Florida's Turnpike, removing long distance commuter traffic from the general purpose lanes. The Florida Department of Transportation (FDOT) will retain control of the toll revenue and toll rates.
