State Road 112 (SR 112) is a 9.9-mile-long (15.9 km) east–west state highway connecting Miami International Airport in Miami to Miami Beach in the U.S. state of Florida. Between the airport and Interstate 95, it is locally known as the Airport Expressway (or the Airport Tollway), and is a controlled-access toll road between SR 9 and I-95. Between I-95 and Alton Road (SR 907A) in Miami Beach, SR 112 is signed only as Interstate 195 as it crosses Biscayne Bay by way of the Julia Tuttle Causeway. Between I-195 and its eastern terminus at Collins Avenue (SR A1A), the SR 112 signs are present but infrequent, and the road is locally maintained as Arthur Godfrey Road.
Since the state of Florida renumbered its Florida State Roads in 1945, a grid system of designation was imposed. While Miami is in a region of Florida in which all three-digit State Roads should begin with an "8" or a "9", its collection of State Roads has a few that begin with a "1" (usually used south of the Georgia state line and near Gainesville and Flagler Beach, both over 300 miles (480 km) away).
