State Road 112(SR 112) is a 9.9-mile-long (15.9 km) east–weststate highwayconnectingMiami International AirportinMiamitoMiami Beachin theU.S. stateofFlorida.Between the airport andInterstate 95,it is locally known as theAirport Expressway(or the Airport Tollway), and is acontrolled-accesstoll roadbetweenSR 9and I-95. Between I-95 and Alton Road (SR 907A) in Miami Beach, SR 112 is signed only asInterstate 195as it crossesBiscayne Bayby way of theJulia 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 asArthur Godfrey Road.

Since the state ofFloridarenumbered itsFlorida State Roadsin 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 theGeorgiastate line and nearGainesvilleandFlagler Beach,both over 300 miles (480 km) away).

Route description

Airport Expressway

I-195 (SR 112) eastbound towardsMiami Beach

SR 112 begins at the main entrance ofMiami International Airport,at the intersection of NW 21st Street andState Road 953(Le Jeune Road), and heads north. From here until the interchange withI-95,the road is known as the Airport Expressway and is maintained by theGreater Miami Expressway Agency(GMX). For its first mile or so, the road runs parallel to SR 953 and an airport runway, with its lanes featuring a dividedleft-hand driving direction.About 0.5 miles (0.80 km) north of the southern terminus, SR 112 features an at-graderailroad crossing,near the eastern end of one of the airport's runways. The road swings to its main east-west orientation past the airport, with its lanes crossing to a normal driving direction just to the east of its partial interchange withSR 948,which also provides limited access toU.S. Route 27.

After crossing NW 37th Avenue, the Airport Expressway passes through its first of two toll gantries, charging $0.35 for vehicles withSunPasstransponders and $0.70 for the remaining Toll-by-Plate users. It also runs roughly parallel to theMetrorailOrange Line, crossing under it just west of NW 32nd Avenue. SR 112 then interchanges withSR 9(NW 27th Avenue), and then NW 22nd Avenue half a mile later. From here, the expressway passes through the second toll gantry (at the location of the former toll plaza), charging the same rates as the first gantry.Near this gantry, SR 112 passes the southern side of theEarlington Heights Metrorail station,where the two lines of the Metrorail system merge, with both the Airport Expressway and the Metro continuing to run parallel eastwards for another 1 mile (1.61 km) or so. Just before SR 112's partial interchange withSR 933(NW 12th Avenue), the Metrorail tracks cross over the Airport Expressway as they curve southwards. About 0.5 miles (0.80 km) later, the Airport Expressway ends at thestack interchangewithI-95(alternatively known as the 36th Street Interchange), with SR 112 and the pavement continuing eastwards asInterstate 195.

I-195

Main article:Interstate 195 (Florida)

The 4.424-mile-long (7.120 km) section of SR 112 connectingInterstate 95in the west withMiami Beachin the east is also designated as I-195. This portion of the route is signed as I-195, with SR 112 becoming anunsigned highway.I-195 and SR 112 crossBiscayne Bayby way of theJulia Tuttle Causeway.AtSR 907A(Alton Road), I-195 terminates while SR 112 continues east as Arthur Godfrey Road.

Surface section

Eastern terminus of I-195 at exit 5

East of Alton Road, SR 112 continues as the palm-linedArthur GodfreyRoad (also known as West 41st Street), a 0.82-mile-long (1.32 km) four-lane surface road. It passes through the southern end ofNautilus,past shops and low-rise office buildings, crossing theBiscayne Waterwaybefore passing along the southern edge of North Beach Elementary School. Continuing past more shops and a hotel, SR 112 crosses theIntracoastal Waterwaybefore immediately meeting the southbound half ofSR A1A.Past here, the road becomes one lane in each direction and meets the northbound half of SR A1A one block later, terminating amidst the high-rises ofMid-Beach.41st Street continues on a short distance into acul-de-sac.

Tolls

Tolls on the Airport Expressway areall electronic,meaning there are no cash transactions. Payment is done either viaSunPasstransponders or via toll-by-plate billing, the latter of which charges double of the former. Two toll gantries are located along the expressway portion of the road, each charging $0.35 for SunPass users and $0.70 for Toll-by-Plate. As of November 15, 2014, it costs $0.70 to travel the entire expressway portion via SunPass (and $1.40 via Toll-by-Plate). All motorists are charged at least one toll for using the road; there are no "free sections" as existed prior to the electronic toll conversion in 2014.

History

Construction of SR 112 began in 1959, and the expressway was opened to traffic on December 23, 1961 (six months after the Palmetto Expressway,SR 826). Its initial name was the36th Street Tollway,but use of the name eventually faded in favor of the more popular "Airport Expressway". Initially the toll road had its western terminus at the congested intersection with LeJeune Road (SR 953), Northwest 36th Street (SR 48), and Okeechobee Road (US 27/SR 25) just east of the airport. It wasn't until 1990 when SR 112 was extended southward and westward onto the airport property, terminating at the main entrance.

The numbering of SR 112 is an anomaly in the current grid-based system. The road was assigned its number while it was in its planning stages;it retained the number as FDOT made widespread changes in the numbering of State Roads in southeastern Florida in the 1970s and early 1980s.

On November 15, 2014, the Airport Expressway became an all electronic toll road, no longer collecting cash, and the only ways to pay are either by theSunPasstransponders or billing by the toll-by-plate program, at double the cost. This also eliminated all "free movement" sections of the tolled section of SR 112, and restored tolls westbound, which had been removed in March 1984. This change was first announced in 2010, and along with the nearby Dolphin Expressway, SR 112 was the last of theMDXexpressways to be converted toopen road tolling.

Interstate 195 Spur

On December 23, 1961, three signed roads along the route of SR 112 were opened: the 36th Street Tollway, Interstate 195, andSpur Interstate 195.I-195 Spur was the surface portion of the east–west state route along Arthur Godfrey Road inMiami Beach,connecting I-195's eastern terminus to SR A1A. The I-195 Spur signs disappeared from the road shortly after the designation was decommissioned by the newly formedUnited States Department of Transportationin the late 1960s, and is now signed solely (but scarcely) as SR 112.

Future

While repeated attempts to secure funding for extending SR 112 along SR 948 to thePalmetto Expresswayand theHomestead Extension of Florida's Turnpikehave failed, theFlorida Department of Transportationis constructing a connector between theDolphin Expresswayand the Airport Expressway as part of a massive project (theMiami Intermodal Center) tying together expressways, rail lines, and the airport. It remains to be seen if the connector will have its own FDOT designation or if the SR 112 will be extended over it to connect the Miami area's two primary east–west expressways.
