Interstate 595 (I-595), also known as the Port Everglades Expressway and unsigned State Road 862 (SR 862), is a auxiliary Interstate Highway that connects I-75 and Alligator Alley in the west with Florida's Turnpike, I-95, Fort Lauderdale–Hollywood International Airport, US Highway 1 (US 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 freeway opening in stages in the late 1980s, with completion in 1991. The reversible tolled express lanes opened in 2014. Route description The Interstate Highway begins in Sunrise as the eastern part of an 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, SR 84 (the former number for Alligator Alley) runs parallel to the freeway, acting as an access road on either side of the Interstate. 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. Three miles east of that interchange, it meets with Florida's Turnpike and US 441. In Fort Lauderdale, I-595 intersects with I-95 at the northwestern end of the airport. At the eastern end of the airport, it has its final interchange with US 1 (which runs concurrently with SR A1A at the interchange), providing access to the airport and Port Everglades. The eastern terminus consists of two lanes for US 1 southbound, two for US 1 northbound and two lanes for Port Everglades via Eller Drive. The exit for southbound US 1 has a ramp to the airport. SR A1A is not listed on the exit signs. History I-595 grew out of a freeway 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
