Transportation in Florida
Transportation in Florida includes a variety of options, including Interstate Highways, U.S. Highways, and Florida State Roads; Amtrak and commuter rail services; airports, public transportation, and sea ports, in a number of the state's counties and regions. Highways. Florida's interstates, U.S. Highways, and state highways are maintained by the Florida Department of Transportation, with the exception of a few highways in Miami, which are maintained by the Miami-Dade Expressway Authority (MDX). Florida's interstate highway system contains 1,473 miles (2,371 km) of highway, and there are 9,934 miles (15,987 km) of non-interstate highway  in the state, such as Florida state highways and U.S. Highways. State highways are numbered according to convention. The first digits of state highways with some exceptions (such as State Road 112 (SR 112) connecting Interstate 95 (I-95) to the Miami International Airport) are numbered with the first digit indicating what area of the state the road is in, from 1 in the north and east to 9 in the south and west. Major north-south state roads generally have one- or two-digit odd route numbers that increase from east to west, while major east-west state roads generally  have one- or two-digit even route numbers that increase from north to south. Roads of secondary importance usually have three-digit route numbers. The first digit "x" of their route number is the same as the first digit of the road with two-digit number "x"0 to the immediate north. The three-digit route numbers also increase from north to south for even numbers and east to west for odd numbers. Following this convention, SR 907, or Alton Road on Miami Beach, is farther east than SR 997, which is Krome Avenue, or the farthest west north-south road  in Miami–Dade County. One notable exception to the convention is SR 826, or the Palmetto Expressway (pictured at the right heading north) which, although even numbered, is signed north-south. State roads can have anywhere from one to four digits depending on the importance and location of the road. County roads often follow this same system. A law introduced on January 1, 2013, required all non US drivers to possess an International Driving License to drive within the state. The Florida Department for Highway Safety and Motor Vehicles issued a statement on February 14, 2013, announcing that the law  would not be enforced. Railways. Intercity rail. Amtrak service exists in Florida. Sanford, in Greater Orlando, is the southern terminus of the Amtrak Auto Train, which originates at Lorton, Virginia, south of Washington, DC. Orlando is also the eastern terminus of the Sunset Limited, which travels across the southern United States via New Orleans, Houston, and San Antonio to its western terminus of Los Angeles; however, service to Florida has been suspended indefinitely in the aftermath of Hurricane Katrina. Florida is served by two additional Amtrak trains (the Silver Star and the Silver Meteor), which operate between New York City  and Miami. In 2015, Amtrak had a total of 1,027,196 boardings and alightings in the state of Florida. Brightline is a higher-speed service connecting Miami, Ft. Lauderdale, and West Palm Beach. It is expected to reach Orlando by 2022 with stations at Orlando International Airport and Disney Springs at Walt Disney World. High Speed Intercity Rail. The Florida Department of Transportation was preparing to build a high-speed rail between Tampa, Lakeland and Orlando. This is the first phase of the Florida High Speed Rail system. Soil work began in July 2010 with the federal government expecting full construction  to begin in 2011. However, Governor Rick Scott declined the federal funding. Florida voters approved a state constitutional amendment in 2000 for the construction of a high-speed rail network. Due to public skepticism about the multibillion-dollar price, voters repealed this amendment. The first segment of this network, projected to have opened in 2009, would have connected Tampa and Orlando, in hopes of alleviating traffic on the busy Interstate 4 corridor. Later segments would have connected Miami, Fort Myers, Jacksonville, Tallahassee, and Pensacola. Airports. Florida has 131 public airports. Florida's seven large hub and medium hub airports, as  classified by the FAA, are the following: Major international airports in Florida which processed more than 15 million passengers each in 2005 are Orlando International Airport (34,128,048 est. 2006), Miami International Airport (32,533,974 est. 2006), Fort Lauderdale-Hollywood International Airport(22,390,285 est. 2006) and Tampa International Airport (19,045,390 est. 2006). Secondary airports, with annual passenger traffic exceeding 5 million each in 2005, include Southwest Florida International Airport (Fort Myers) (7,518,169 est. 2006), Palm Beach International Airport (West Palm Beach) (7,014,237 est. 2006), Jacksonville International Airport (5,741,652). Regional Airports which processed over one million passengers each in 2005 are Pensacola (1,638,605), Sarasota -Bradenton (1,337,571), and Tallahassee (1,129,947) and Sanford (1,649,237) which is primarily served by international charter airlines.

Canals. Florida is part of the Intracoastal Waterway, a 3,000 mile (4,800 km) inland waterway. Florida has the Okeechobee Waterway, St. Lucie Canal (C-44), Miami Canal and the Cross Florida Barge Canal. Public transportation. Miami's public transportation is served by Miami-Dade  Transit, which runs Metrorail, a heavy rail rapid transit system; Metromover, a people mover train system in Downtown Miami; and Metrobus, Miami-Dade's bus system. Metrorail runs throughout Miami-Dade County and has 23 stations on a track connecting to Downtown Miami's Metromover and Tri-Rail. Metromover has three lines and 21 stations on a track connecting Uptown and the Brickell Financial District inside of Downtown Miami. Outside of Miami-Dade County, public transit in the South Florida metropolitan area is served by Broward County Transit and Palm Tran; intercounty heavy rail service is provided by Tri-Rail , with 18 stations including the region's three international airports. Tampa and its surrounding area is served by buses run by Hillsborough Area Regional Transit, or "HART" for short. In addition, "HART" runs continuous trolley services in downtown Tampa in the form of the TECO Line Streetcar, a heritage streetcar line sponsored by Tampa Electric Company. Pinellas County and St. Petersburg provide similar services through the Pinellas Suncoast Transit Authority, or "PSTA" for short. The beaches of Pinellas County have their own bus system run by "PSTA" called the "Suncoast Beach Trolley". Downtown St. Petersburg also has a separate bus  system, known as "The Looper". The Cross-Bay Ferry has connected Tampa's Channelside District to Downtown St. Petersburg since 2016. Greater Orlando utilizes the Lynx bus system, which also operates a free bus rapid transit service in downtown Orlando. A commuter rail service – SunRail – also serves the Metro Orlando area. The Walt Disney World Resort is also located in this area and is served by Disney Transport, its own internal transportation system consisting of buses, watercraft, parking lot trams, and the Walt Disney World Monorail System. The latter is one of the busiest mass transit rail systems in North  America, with over 150,000 riders served each day. Public transportation in Jacksonville is provided by Jacksonville Transportation Authority (JTA), operating bus service, trolleys, paratransit, and a people mover. The people mover, known as the JTA Skyway is located in downtown Jacksonville, and operates 8 stations along a track. Bus service as well as paratransit service is provided around Duval County and partially in Clay County. JTA operates three trolley lines in three different neighborhoods: Downtown, Riverside, and Jacksonville Beach. The entire JTA system has a daily ridership of over 42,000. In Volusia County, VoTran provides bus transportation throughout the entire  county. Express service to Orlando was provided between 1998 and 2014 and has since been replaced by SunRail. In Polk County, the Citrus Connection and Winter Haven Area Transit (WHAT) provide regional transportation in the cities of Lakeland, Bartow, Winter Haven, Auburndale and smaller surrounding municipalities and unincorporated areas. WHAT connects with the Lynx system at Haines City. The Gainesville metropolitan area is served by the fourth largest public transit system in the state of Florida. Gainesville Regional Transit System or RTS presently serves 40 city routes (19 on Saturdays, 16 on Sundays), 10 campus routes, and five "Later Gator
