context_page_description: The Dolphin Expressway is a 15-mile-long, six-lane, divided controlled-access highway, with the westernmost 14 miles as an all electronic tollway signed as State Road 836, and the easternmost 1.292 miles between Interstate 95 and SR A1A cosigned as Interstate 395. The road currently extends from just north of the intersection of Southwest 137th Avenue and U.S. Highway 41 in Tamiami, eastward past the Homestead Extension of Florida's Turnpike and Miami International Airport, before intersecting I-95, becoming I-395 and ending at SR A1A in Miami at the west end of the MacArthur Causeway. The Dolphin Expressway is maintained and operated by the Miami-Dade Expressway Authority, while the I-395 section is maintained by the Florida Department of Transportation. The Dolphin Expressway from the Palmetto Expressway to I-95 opened in 1969, with the I-395 section opening in 1971, the extension to the HEFT opening in 1974 and a second western extension opening in 2007.
context_section_description: The highway begins just north of the intersection of Southwest 137th Avenue (unsigned SR 825) and U.S. Highway 41 (SR 90) in Tamiami, built in 2007 and initially accessible only to motorists with SunPass transponders, passing through the first toll gantry. The expressway heads east towards the Homestead Extension of the Turnpike, and then passes through the second of four toll gantries. It then intersects with the Palmetto Expressway (SR 826) at the recently rebuilt Dolphin-Palmetto Interchange, and passes through the southern end of the Miami International Airport. With the failure of FDOT to build either the previously planned airport spur or the proposed LeJeune Road Expressway to give additional access to the airport, Miami-Dade County's sole complete east–west throughway is now often congested, most commonly in the stretch between the Palmetto Expressway (SR 826) and LeJeune Road (SR 953). During this stretch, the expressway have interchanges with NW 72nd Avenue, a third toll gantry, NW 57th Avenue, and a partial with NW 45th Avenue before reaching LeJeune Road. East of the interchange with the airport at LeJeune Road, The expressway has interchanges with NW 37th Avenue and NW 27th Avenue (SR 9), and then reaches the fourth and final toll gantry just west of downtown. The highway has two more interchanges in the fringes of downtown with NW 17th Avenue and NW 12th Avenue before intersecting with I-95 at the Midtown Interchange and becoming a free road and unsigned as Interstate 395 goes into downtown Miami.
  I-395 heads east as an elevated, six-lane expressway into downtown Miami. The feeder lanes from I-95 to eastbound I-395 make up a separate three lane ramp to the right of I-395, with the exit to US 1/US 41 being a left exit from the I-395 lanes and a right exit from the I-95 feeder lanes. The feeder lanes then merge into three lanes, heading east towards the MacArthur Causeway, with I-395 and SR 836 terminating just east of an entrance ramp with US 1 (SR 5)/US 41, and continuing as SR A1A.
