Interstate 195 and Florida 112

Interstate 195 Routing

Interstate 195 is a spur route from Interstate 95 to Alton Road in Miami Beach, serving Miami's upper east side. Part of Interstate 195 is the Julia Tuttle Causeway which carries the Interstate across Biscayne Bay. The freeway continues west of Interstate 95 as Toll Florida 112/Airport Expressway and east of Florida 907 as Florida 112. The entire route of Interstate 195 is secretly Florida 112 designation, with extant sections of Florida 112 at either end of the Interstate route.

According to the Florida DOT Exit Numbering List, Interstate 195 has the following exits:

  • Exit 1 - Interstate 95 (westbound)
  • Exit 2A - North Miami Avenue (eastbound)
  • Exit 2B - U.S. 1 (Biscayne Boulevard) to U.S. 27 (Allapattah Road) west
  • Exit 5 - Florida 907 (Alton Road) and Florida 112 (West 41st Street/Arthur Godfrey Road) (eastbound)

Interstate 195 History

Construction on Interstate 195 began in 1959 along with construction of Interstate 95 and the Airport Expressway. Part of Interstate 195's construction involved building the brand new Julia Tuttle Causeway as an alternative route to Miami Beach and to alleviate the MacArthur and Venetian causeways. The MacArthur Causeway predates the Interstate era and explains why it is not designated part of Interstate 395 to the south.

Interstate 195 opened on December 23, 1961, along with the connecting sections of Interstate 95 and Florida 112/Airport Expressway. The new Julia Tuttle Causeway was named for Julia Tuttle, an early Miami pioneer who was instrumental in creating the city.

According to the FDOT Biennial Report 1963-1964, a Business Spur I-195 used to exist in Miami Beach. This designation was given to Arthur Godfrey Road, which is a surface street that continues east of the Florida 907 interchange. Today that business spur is signed as Florida 112/Arthur Godfrey Road. It is unknown exactly when it was decommissioned and why it no longer exists today. This spur route was like several business spurs that still exist in South Carolina, including Business Spur I-126, Business Spur I-385, Business Spur I-526, and Business Spur I-20. Each of these routes reach their endpoint, and the continuing surface street has green shields that direct the continuation of the route off the freeway portion. It is too bad Business Spur I-195 was not continued in Miami Beach.

Florida 112/Airport Expressway is not part of Interstate 195 because Interstate funding for that freeway was not available. Rather than wait for more Interstate money, the city and state decided to build the route to allow for needed access between the airport and the beaches. As a result, it was built and funded as a toll road, which at the time was not eligible for being signed as an Interstate Highway. Therefore, the Airport Freeway and Julia Tuttle Causeway carry two separate route numbers, even though the two routes share the same general path.

Florida 112 Routing

The Airport Expressway (Florida 112) is a six- to eight-lane freeway from Miami International Airport (MIA) east to Interstate 95 and Interstate 195 for a distance of 5.4 miles. It is maintained by the Miami-Dade Expressway Authority. The freeway parallels N.W. 36th Street for its entire length, which runs to the south of the expressway and continues east of Interstate 95 as Interstate 195 (secret Florida 112).

For those who follow the specific grid system in use in Florida, Florida 112 does not fit in that numbering system at all. (See Florida's State Road Numbering System for more.) Florida 112 lies between Florida 80 and Florida 90, so a logical route number probably should have been in the 800s (like Florida 836). However, the Florida 112 designation was created early in the process, and it was left in place even as secondary routes were renumbered for other reasons in the 1970s and 1980s.

Florida 112 was originally named the "36th Street Expressway," which is based on the concept that the new freeway would replace parallel U.S. 27 (N.W. 36th Street/Generals Boulevard/Allapattah Boulevard) as the through route. When poet Robert Frost died, the highway was renamed for him since he resided in Miami at the time of his death. However, neither of these names stuck: It is instead known as the Airport Expressway or simply "the 112."

Florida 112 History

The Airport Expressway was constructed between 1959 and 1961 along with connecting sections of Interstate 95 and Interstate 195. Its interchange with the two respective Interstates is a three-level stack. The highway opened on December 23, 1961. Florida 112 was constructed in what was a heavily urbanized area, and the new freeway displaced many existing homes and businesses, as it took up an entire block between N.W. 39th Street and N.W. 40th Street.

Currently, Florida 112 is tolled only in the eastbound direction. Originally Florida 112 had toll plazas in both directions. Increasing traffic on Florida 112 prompted the removal of the westbound toll in March 1983. The eastbound toll was increased from ten cents to a quarter. The physical toll booths were removed permanently a year later, in March 1984. The same thing also happened on Florida 836/Dolphin Expressway to the south during that timeframe.

Florida 112 saw a fair amount of improvements. In 1987, Florida 112 was widened from six to eight lanes between Interstate 95 and N.W. 22nd Avenue. Flyover connector ramps to and from Interstate 95 were added later that year as part of the installation of high occupancy vehicle (HOV) lanes. These HOV lanes were constructed on Interstate 95 starting between 1986 and 1990; they finally offered relief to carpools when they opened on December 12, 1990.

Another improvement allowed Florida 112 to connect directly with the Miami International Airport. Originally, Florida 112 terminated at the intersection of Florida 953/N.W. 42nd Avenue (LeJeune Road) and U.S. 27/Florida 25/Okeechobee Road just north of the airport. As a result, airport traffic had to use busy Florida 953/LeJeune Road south. Between December 1988 and March 1991, a pair of two-lane ramps were constructed to take motorists from Florida 112/Airport Expressway directly to the entrance to Miami International Airport.

In December 1994, the Miami-Dade Expressway Authority (MDX) was created, and two years later the Florida Legislature allowed MDX to assume operational and financial control of five expressways from FDOT - Florida 112, Florida 836, Florida 874, Florida 878, and Florida 924. Coincidentally, all but one (Florida 878) are toll expressways. In 2000-2001, MDX replaced the standard state road shields on the toll expressways with the "TOLL" shields found throughout the rest of Florida.

Florida 112 Future Aspirations

In October 1989, a $1.1 billion wish list of transportation improvements was approved by the Dade County Metropolitan Planning Organization. One of the proposed improvements would have extended Florida 112 west of its current terminus at Miami International Airport to the Homestead Extension of Florida's Turnpike (HEFT). The list was submitted to the state, but the extension of Florida 112 did not make the cut due to funding. If the plan did get serious support, it would be a much-needed alternative to the failing Dolphin Expressway, the only full east-west expressway across the county. The proposal stands only a limited chance of being considered, mostly because of Doral located in its path, resultant citizen protest, and the cost to build such a highway through an urbanized area.

Eastbound Florida 112
Eastbound Interstate 195
After the Interstate 95 and Florida 112 interchange, Interstate 195 begins its eastbound journey from Miami to Miami Beach. This image shows the transition from northbound Interstate 95 onto eastbound Interstate 195. Incoming traffic from eastbound Florida 112 is coming in from the left. Photo taken 12/28/03.
The first exit along eastbound Interstate 195 is Exit 2A, North Miami Avenue. Unlike other streets in the city of Miami, Miami Avenue is not N.W. or N.E. This is because Miami Avenue acts as the dividing line between east and west prefix designations on streets in this area. All city streets east of Miami Avenue and north of Flagler Street (Florida 968, the east-west meridian) have the prefix "N.E." Photo taken 12/28/03.
Interstate 195 fits into three eastbound lanes as it reaches Exit 2A, North Miami Avenue. Only one exit remains in Miami before Interstate 195 crosses the Intracoastal Waterway en route to Miami Beach. Photo taken 12/28/03.
The next exit is Exit 2B, Junction U.S. 1, Biscayne Avenue and U.S. 27, N.E. 36th Street. This interchange marks the southern terminus of U.S. 27, which functions as an east-west route in Miami, parallel to Interstate 195 and most of Florida 112. U.S. 1 travels north to Bay Point and south to Downtown. Photo taken 12/28/03.
Many of the reassurance markers along Interstate 195 in both directions are neutered, narrow-width shields. The numerals are a medium Series C, which enables the digits to fit into the smaller shield. Photos taken 12/28/03.
Eastbound Interstate 195 reaches Exit 2B, Junction U.S. 1 and U.S. 27. U.S. 27 is not signed here, even though the loop ramp exit actually turns 180 degrees to meet U.S. 1 at the intersection of Biscayne Avenue and N.E. 36th Street, which is the southern terminus of U.S. 27. It is a rather obscure ending to a major route through the state of Florida. U.S. 27 is not signed in the other direction, either. Photo taken 12/28/03.
Whereas the U.S. 1 interchange marks the eastern terminus for Interstate 395, the U.S. 1 interchange marks the beginning of the Julia Tuttle Causeway over the Intracoastal Waterway. There are no exits for the next three miles. Since the causeway was built to Interstate standards and with Interstate funds, the entire length of the causeway is signed as Interstate 195, unlike the MacArthur Causeway, which is signed as Florida A1A rather than Interstate 395. Photo taken 12/28/03.
Coming off the raised bridge, which is higher to allow for boats that require more clearance, Interstate 195 descends onto this filled island in the Biscayne Bay. There is no development on this narrow strand, and there are no places to stop along the way. The entire island is carpeted with lush grass and tropical plants. Photo taken 12/28/03.
Another narrow Interstate 195 shield is located at the base of the tall bridge on the island. Photo taken 12/28/03.
Interstate 195 is the sole Interstate Highway to enter the city limits of Miami Beach. Founded in 1913 by John Collins and Carl Fisher, Miami Beach exploded in the post-World War II era along with Miami. Once surrounded by mangrove forests and sand bars, Miami Beach today is a mecca to vacationers world wide. The beach is wide with white sand, and colorful people grace the sidewalks and shops adjacent to the water. Toward the southern end of the beach is a topless section, and a gay and lesbian community has flourished in Miami Beach (South Beach) for years. Miami Beach can be noted by passengers on incoming airplanes due to its uniquely colorful skyline of condominiums, apartments, and hotels. However, the skyline is not visible from this part of Interstate 195. Photo taken 12/28/03.
The first exit in Miami Beach is Exit 5, Junction Florida 907. Use Florida 907 (Alton Road) to Miami Beach's Convention Center, Jackie Gleason Theater, and Art Deco District. Interstate 195 prepares to depart the island and cross Biscayne Bay one more time to enter Miami Beach. Photo taken 12/28/03.
The northern end of the Miami Beach skyline comes into view here as Interstate 195 crosses the second high bridge before reaching Miami Beach. Photo taken 12/28/03.
Eastbound Interstate 195 reaches Exit 5, Junction Florida 907/Alton Road. Florida 907 acts as an alternative to Florida A1A through Miami Beach. While Florida A1A follows Collins Avenue along the east side of the island, Florida 907 follows Alton Road on the west side of the island. Florida 907 certainly loses out in popularity to its glamourous cousin Florida A1A, but Florida 907 carries a great deal of traffic north-south through Miami Beach. The left two lanes of Interstate 195, in fact, continue straight ahead as Godfrey Road eastbound to Florida 907A and Florida A1A. Photo taken 12/28/03.
At the Exit 5 gore point, Interstate 195 loses a lane, and the four-lane freeway continues east briefly before changing into a surface street at the intersection with Florida 907A (Alton Road). Photo taken 12/28/03.
Interstate 195 ends just prior to the Florida 907A traffic signal in Miami Beach. The freeway does not extend all the way to Florida A1A. Photo taken 12/28/03.
Although unsigned, Interstate 195 reverts to its hidden designation, Florida 112. Florida 112 follows Godfrey Road between Alton Road (Florida 907A) and Collins Avenue (Florida A1A). Note that Florida 907 and Florida 907A are both signed as Alton Road; this is because Alton Road splits into two components (one through and one local) in the vicinity of Interstate 195. The two state routes merge together north and south of the interchange. Photo taken 12/28/03.
Finally reaching the Alton Road traffic signal, Interstate 195 ends and Florida 112 resumes. Photo taken 12/28/03.
Westbound Florida 112/Godfrey Road
In Miami Beach, westbound Florida 112 follows Godfrey Road. The last intersection along westbound is with Florida 907A, Alton Road. There is no direct connection to Florida 907 except via North Bay Road (see two photoboxes below). Photo taken 12/28/03.
Westbound Florida 112/Godfrey Road meets Florida 907A/Alton Road. Florida 112 becomes a secret route as Interstate 195 begins its westbound journey just beyond this intersection; it will reemerge west of Interstate 95 on the Airport Expressway. Photo taken 12/28/03.
Westbound Interstate 195
The westbound Interstate 195 freeway begins after this intersection with Florida 907/North Bay Road in Miami Beach. No Florida 907 shields are present, but the street sign for North Bay Road can be seen on in this picture. There are no further exits that connect with the Miami Beach street network; the next exit along westbound is Exit 2B, junction U.S. 1 (in Miami). Photo taken 12/28/03.
These are the first shields for Interstate 195 westbound as the nascent freeway prepares to leave Miami Beach. Note that the route is cosigned as "TO Interstate 95." Photo taken 12/28/03.
Shimmering, blue Biscayne Bay is visible to the north of the Julia Tuttle Causeway. Photo taken 12/28/03.
Westbound Interstate 195 crosses this island as part of its journey on the Julia Tuttle Causeway. Julia Tuttle was an early landowner in Miami who purchased 640 acres on the North Bank of the Miami River, near the heart of Miami. She encouraged Henry Flagler to bring his railroad south to the Miami region. Photo taken 12/28/03.
The Miami International Airport is seven miles ahead via Interstate 195 west and Florida 112 west. U.S. 1 travels north to Bay Point and south to Downtown. Photo taken 12/28/03.
This reassurance shield is located on the north side of the Julia Tuttle Causeway along westbound Interstate 195. Note the extra wide shoulder and planted area that separates the bridge from the water. Photos taken 12/28/03.
The next exit along westbound is Exit 2B, Junction U.S. 1 (Biscayne Boulevard) to U.S. 27 (N.E. 36th Street) west. Photo taken 12/28/03.
The freeway crosses over a second tall bridge to reach the mainland. Note the Julia Tuttle Causeway sign here, which touts an artificial reef. Photo taken 12/28/03.
A Florida's Turnpike trailblazer appears after the bridge, even though the toll road is several miles away from here. To get to the northbound Turnpike, use Interstate 95 north to the Golden Glades Interchange. To reach the southbound Turnpike, use Interstate 95 south to Florida 836/Dolphin Expressway west. Photo taken 12/28/03.
Interstate 195 is not signed on the pull-through sign now that the freeway has reached the mainland. The offramp connects to Exit 2B, Junction U.S. 1 (Biscayne Avenue). Use Biscayne Avenue south to the U.S. 27 (N.E. 36th Street) intersection. Photo taken 12/28/03.
The final exit along westbound Interstate 195 is Exit 1, Junction Interstate 95 north to Fort Lauderdale and south to downtown Miami. The mainline freeway continues westbound as Florida 112, the Airport Expressway. Photo taken 12/28/03.
Florida 112 continues west in the left two lanes, while the right two lanes prepare to exit onto Interstate 95. The far right lane connects to northbound Interstate 95, while the middle lane connects to southbound Interstate 95. Photo taken 12/28/03.
Interstate 195 ends as the freeway splits between Florida 112 (left two lanes) and Interstate 95 (right two lanes). The freeway continues east on Florida 112 to Miami International Airport, northbound U.S. 27/Okeechobee Road, and Interstate 75. There is no END Interstate 195 shield present. Photo taken 12/28/03.
Now in the stack interchange between Interstate 195, Interstate 95, and Florida 112, the ramp from westbound Interstate 195 to westbound Florida 112 reduces from two lanes to one lane. Photo taken 12/28/03.
This stack interchange is almost a symmetrical stack, except that it has connections for the high occupancy vehicle lanes as well as other intervening ramps. Photos taken 12/28/03.
A pair of newer ramps are visible in this scene. Photo taken 12/28/03.
The single lane transition ramp from westbound Interstate 195 to westbound Florida 112 will become the left lane of the Florida 112 freeway, as seen here. Photo taken 12/28/03.
Westbound Florida 112/Airport Expressway
After the Interstate 95 and Interstate 195 transition, the first exit along westbound Florida 112/Airport Expressway is Exit 4B, N.W. 17th Avenue, followed by Exit 4A, N.W. 22nd Avenue. To continue west on Florida 112, use the left three lanes. Photo taken 12/28/03.
In 1996, the Florida Legislature named Florida 112 as the Dewey Knight, Jr. Memorial Highway. Dewey Knight was a former Miami-Dade Assistant County Manager who oversaw a "blue-ribbon panel" that would help desegregate Miami-Dade County's federally-assisted housing programs. In addition, Knight developed ways to increase housing opportunities for residents of public housing who historically were afforded limited choices. This sign is mounted at the base of the Metro Rail overpass that carries the tracks from downtown Miami onto a corridor parallel to Florida 112. Photos taken 12/28/03.
Even though an exit tab is placed above the N.W. 17th Avenue exit, it is not signed as Exit 4B. The right lane is exit only onto N.W. 17th Avenue, and westbound Florida 112 continues in the left four lanes. Photo taken 12/28/03.
Currently, tolls are only collected in the eastbound direction. While this one-way toll collection has saved money, it is possible that westbound tolls may be reinstituted given advances in electronic tolling technology and what are considered best practices for offering high occupancy vehicle lanes that dually function as toll lanes for single occupancy vehicles. No tolls are currently planned for westbound, but that may change, especially after the freeway is reconstructed. But for now, westbound is untolled. Photo taken 12/28/03.
The next exit along westbound is Exit 4A, N.W. 22nd Avenue. This major city street offers a north-south arterial corridor through Miami. Photo taken 12/28/03.
A substandard exit for N.W. 22nd Avenue is in place due to limited real estate and the need to fit this exit ramp under the Metro Rail viaduct. The Earlington Heights Metro Rail station is visible on the platform behind the exit ramp. Photo taken 12/28/03.
Westbound Florida 112/Airport Expressway closely follows the Metro Rail (visible to the right/north) as it continues toward Miami International Airport. Metro Rail will only follow Florida 112 for a brief distance before it turns north along the Florida 9 corridor and Florida 934 corridor. The freeway may change dramatically if plans to reconstruct the road to increase capacity are realized. Photo taken 12/28/03.
Florida 9 (Exit 3) is the next exit. Florida 9 follows N.W. 27th Avenue through Miami, and it travels south to terminate at U.S. 1 (Dixie Highway). Looking north, Florida 9 connects with the region's major freeways and U.S. 441 at the Golden Glades Interchange. Photo taken 12/28/03.
The six-lane Florida 112 freeway approaches its western terminus. For some reason, route shields are not widely used on this stretch. Florida 112 more or less ends at its interchange with Florida 953 (LeJeune Road), but the direct connection between Florida 953 and Miami International Airport is achieved by mainline Florida 112/Airport Expressway turning south, parallel to Florida 953. These signs indicate the destinations for the next three exits: Exit 2B (next right) is U.S. 27 north to Hialeah, Exit 2A is Florida 953 north to Miami Springs, and Exit 1B is Florida 953 south to Coral Gables. Photo taken 12/28/03.
Road construction becomes evident as Florida 112 approaches the off-ramp to northbound U.S. 27/Florida 25, Okeechobee Road. For the entire length of Florida 112 from U.S. 1 west to this exit, U.S. 27 has followed Florida 112 parallel to the freeway. However, from here U.S. 27 travels northwest for the first time, following the Miami Canal en route to Lake Okeechobee. U.S. 27 is a major route that connects South Florida with Central Florida, passing through the interior of the Florida Peninsula. Photo taken 12/28/03.
A butterfly gantry overhead sign is used at the gore point for the exit onto northbound U.S. 27 (Okeechobee Road). Note the faded Tri-Rail insignia placed next to the U.S. 27 shield, which found here for the first time on an overhead sign. The left three lanes continue west along Florida 112, but the next exit (Florida 953/LeJeune Road north) follows immediately after the overpass visible here. Photo taken 12/28/03.
Westbound Florida 112 (Airport Expressway) reaches Exit 2A, Junction Florida 953 (Le Jeune Road) north to Hialeah, with connections to Interstate 75 via Florida 924. The left two lanes continue straight ahead toward Miami International Airport. Photo taken 12/28/03.
The penultimate exit along westbound Florida 112 is Exit 1B, Junction Florida 953 (Le Jeune Road; NW 42nd Avenue) southbound to Florida 836 (Dolphin Expressway) and Rental Car Return. Busy Florida 953 carries a good amount of north-south traffic since it is close to Miami International Airport and is approximately mid-way between Florida 826 (Palmetto Expressway) and Interstate 95. The left lane exits onto Florida 953 south; the right lanes continue into Miami International Airport (Exit 1A). Photo taken 12/28/03.
This view shows the transition ramp from westbound Florida 112 (left exit) onto southbound Florida 953 (Le Jeune Road). There is no direct connection to northbound Florida 953 from here (for northbound, use Exit 2A instead). Photo taken 12/28/03.
Florida 953 continues south from this point, carrying traffic to Florida 836, the Dolphin Expressway. If you take Florida 953 south, you can use Florida 836 east back to Miami and Miami Beach and west to Florida 826 (Palmetto Expressway), U.S. 41, and Interstate 75. Florida 953 continues south until ending at U.S. 1 near Coral Gables. Photo taken 12/28/03.
