State Road 836, locally known as the Dolphin Expressway, is a 15.373 miles (24.740 km)-long six-lane divided expressway, with the westernmost 14.081 miles (22.661 km) being a tollway, and the easternmost 1.292 miles (2.079 km) of SR 836 between I-95 and SR A1A is signed Interstate 395. The road currently extends from just north of the intersection of Southwest 137th Avenue and U.S. Route 41 (SR 90) in Tamiami, eastward past the Homestead Extension of Florida's Turnpike (SR 821) 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 FDOT. 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.
Route description 
The highway begins just north of the intersection of Southwest 137th Avenue and U.S. Route 41 (SR 90) in Tamiami, as a SunPass only section of the expressway, built in 2007 and accessible only to motorists with SunPass transponders. The expressway heads east towards the Homestead Extension of the Turnpike, and then passes through the first of two toll barriers. It then intersects with the Palmetto Expressway (SR 826), and passes through the southern end of the Miami International Airport. With the failure of the Florida Department of Transportation 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). East of the interchange with the airport at LeJeune Road, eastbound lanes pass through a second toll barrier just west of downtown. The highway has two more interchanges in the fringes of downtown 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.
Until July 1, 2007, the toll for eastbound automobiles was $1.25 ($1.00 for motorists with SunPass), paid at a toll booth between Northwest 22nd and Northwest 17th Avenues (toll is not collected from westbound traffic). In conjunction with the completion of the new three-mile-long extension west of the Turnpike, tolls of $1.00 (75 cents for motorists with SunPass) are now collected from traffic in both directions west of SR 973 (Northwest 87th Avenue/Galloway Road). Although the new toll was originally stated to be only for the extension, motorists going to the Florida Turnpike or Northwest 107th Avenue also have to pay. Thus, the total toll for eastbound traffic traveling along the expressway from the Turnpike to Interstate 95 is now $2.25 (or $1.75 for motorists with SunPass). Traffic traveling the new SunPass-only extension to/from Northwest 137th Avenue pays an additional 25 cents.
Originally envisioned as the Twentieth Street Tollway in 1964 (with a spur to the airport along LeJeune Road), construction on the Fourteenth Street east–west Expressway between the Palmetto Expressway and US 1 started in 1967 and was completed in 1969. Two years later, construction of the western extension to Florida's Turnpike commenced, and was finished in 1974. Also in 1974, the name of the tollway was changed to commemorate the success of the Miami Dolphins of the NFL, after back-to-back wins in the Super Bowl.
The section of SR 836 signed as I-395 was supposed to open with the rest of the Dolphin Expressway in 1968, but was delayed due to a freeze at the federal level for road spending. The expressway opened on March 26, 1971.
Construction of a second westward extension of SR 836 started in 2004. This extension, westward to Northwest 137th Avenue near Northwest 12th Street, opened June 22, 2007, accessible only to motorists with SunPass electronic toll-paying capability; there is no capacity for the collection of cash.
Short range plans include the construction of additional lanes and a redesign of a heavily-used interchange with SR 826. A planned third extension (southward to Southwest 136th Street) is currently being considered.
On May 24, 2010, construction began on the Miami Port Tunnel, a $1 billion project that will connect the port to other major highway arteries, including I-395, with the tunnel expected to open in 2014.
