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.

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.

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.

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.

[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.

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.
