Interstate 4

Interstate 4 Florida


Located wholly within the Sunshine State, Interstate 4 comprises a southwest to northeast route across the Florida peninsula, connecting the metropolitan areas of Tampa-St. Petersburg, Lakeland-Winterhaven, Orlando and Daytona Beach. With the ever expanding population and development in Florida, I-4 is a major transportation corridor that was inadequate at its original four lanes. Various construction programs completed between the mid 1990s and 2008 improved the capacity of the route between Tampa and Orlando, with widening underway in Volusia through to spring 2016. In 2002, exit numbers along Interstate 4 were changed from sequential to a mileage basis as part of a system wide renumbering.

Parallel U.S. Routes

Interstate 4 parallels U.S. 92 eastward from Tampa to Lakeland, with the two running close by through Mango and Plant City. Where I-4 shifts northeast, U.S. 92 stays east, leaving the freeway for Auburndale, Winter Haven and Haines City. U.S. 92 turns north at Haines City along an overlap with U.S. 17 to Kissimmee, but staying somewhat distance from I-4. U.S. 441 combines with the pair from Kissimmee through Orlando along Orange Blossom Trail, which converges with the I-4 corridor southwest of Downtown Orlando.

U.S. 441 branches northwest to Apopka at the U.S. 17 & 92 eastern turn onto Colonial Drive ahead of I-4. The pair extend northward to Maitland, Casselberry and Lake Mary to cross paths with I-4 again at Sanford. U.S. 17 parts ways with U.S. 92 and the I-4 vicinity at DeLand for Palatka while U.S. 92 turns east through Tomoka Wildlife Management Area. Two wye interchanges and a connector join I-4 and U.S. 92 to the west of their respective interchanges with I-95 at Daytona Beach.

Planned Improvements

Through Orange and Seminole Counties along with the city of Orlando, a variety of improvements were proposed, most of which were controversial. In October 2003, the "Mobility 20/20" tax plan proposed an expanded Interstate 4 through the metropolitan area, but that was rejected by voters. One of the reasons cited for the failure of this tax was opposition to toll lanes on I-4. Nevertheless, the idea returned in March 2005.

During that time, officials proposed a managed lanes concept that is similar to the reversible and high occupancy vehicle lane concept found in Southern California, such as California 91 (Riverside Freeway) and Interstate 15 (Escondido Freeway). These highways feature managed lanes in the median that can be adjusted to allow for more traffic in either direction. High occupancy vehicles use the lanes for free, while single occupancy vehicles are charged an electronic toll to use the lanes. Called XPress 400, these new lanes would cost over $1.5 billion to complete (2005 estimate) and would be managed by the Florida Turnpike Enterprise. The project would install the new toll lanes in the median, add a continuous fourth lane in both directions, straighten out some sections of the freeway, and reconstruct interchanges. The project was proposed to span from Florida 435 (Kirkman Road) to Florida 434. Completion was envisioned by 2013.1

The Trans4mation project resulted in some improvements to area interchanges, such as the building of a new flyover from I-4 west to John Young Parkway and completion of Phase 1 of the I-4 and SR 408 (East West Expressway) interchange upgrade. The remainder of work is now apart of the I-4 Ultimate Project. The new initiative focuses on 21 miles of Interstate 4, from south of SR 435 (Kirkman Road) in Orange County to north of SR 434 in Seminole County. The $2.3-billion project kicked off in early 2015 and runs through early 2021. Work focuses on rebuilding 15 interchanges, replacing 75 bridges and adding 4 Express (toll) Lanes along the median of Interstate 4.


As originally planned, Interstate 4 continued southwest on what is now Interstate 275 from its western terminus across the Howard Frankland Bridge into St. Petersburg; at that time, I-275 north of I-4 was Interstate 75. Some plans extended Interstate 4 further west from Downtown St. Pete to the Gulf of Mexico, but that section was never constructed.

The extension of Interstate 75 south to Fort Myers and Naples in 1971 replaced Interstate 4 west from the Downtown Interchange in Tampa to Pinellas County. The 1971 General Drafting Map of Florida shows the Howard Frankland Bridge co-signed as Interstate 4 and Interstate 75; by 1973, the bridge was shown as Interstate 275, with Interstate 75 rerouted onto a new alignment to the east of Tampa.

The following are key dates in the history of Interstate 4:2

  • 1959 - Interstate 4 opened from Plant City to Lakeland (first segment to open). Interstate 4 under construction (1) from Tampa to Plant City and (2) on the Howard Frankland Bridge (which was then part of Interstate 4)
  • 1960 - Interstate 4 opened along (1) the Howard Frankland Bridge, (2) from East Tampa east to Lakeland, and (3) from Lake Monroe to near Lake Helen. Proposed (as yet unconstructed) sections that year on Interstate 4 included those in St. Petersburg, in Tampa, from Lakeland to Orlando, and from Lake Helen to Tiger Bay State Forest.
  • 1961 - Interstate 4 opened from Lakeland to Orlando and under construction from Lake Helen east to Daytona Beach. Sections still unconstructed and proposed included segments in St. Petersburg, in Tampa, and from Orlando to Sanford.
  • 1963 - The only section of Interstate 4 in Tampa that had still not yet built was between Armenia and 22nd Street.
  • 1963 - In Orlando, Interstate 4 was complete up to Robinson Street and was labeled "Orlando Expressway."
  • 1969 - Interstate 75 extended south, sharing an alignment with Interstate 4 from Tampa southwest to St. Petersburg.
  • 1971 - Beginning of Interstate 4 truncated to the Downtown Interchange with Interstate 75 (renumbered Interstate 275 in 1973) in Tampa. Interstate 4 now complete from Interstate 275 in Tampa to Interstate 95 in Daytona Beach.

Adjacent Toll Roads

Several toll roads have been constructed to provide an alternate to Interstate 4 and commuter routes throughout Central Florida. Some of these routes include the Lee Roy Selmon Expressway (SR 618) at Tampa; the Polk Parkway (SR 570) around Lakeland; the Central Florida Greeneway (SR 417) around the east side of Orlando and the Daniel Webster Western Beltway (SR 429) around the west side of Orlando. The Wekiva Parkway (SR 429) is currently under construction to extend the Western Beltway north to Sanford.

Florida 400

Every state-maintained highway in Florida has a state road designation. In the case of Interstate 4, it is State Road 400. Although it is not signed for most of its length, a portion of the route is signed at the east end. Within Daytona Beach, Florida 400 stems east from the interchange between Interstates 4 and 95 (Exit 260) as a four-lane boulevard to meet U.S. 1.

The aforementioned "XPress 400" toll lanes plan was so named because of the hidden state road designation for Interstate 4.

The junction between Interstate 4 and SR 408 (East-West Expressway) is one of the busiest along the 132-mile freeway. The Ultimate I-4 project will complete the redesign of the exchange into a high-speed interchange.
Tampa Bay - 1971.
Interstate 75 was extended south to Naples in 1971, replacing the westernmost stretch of I-4 from the Downtown Interchange in Tampa to St. Petersburg in Pinellas County. While in the transition period that year, General Drafting opted to show both routes as cosigned across the Howard Frankland Bridge.
The 1963 Florida Official Highway Map shows that the bulk of Interstate 4 was already open to traffic. The freeway was completed northward to Robinson Street (SR 526) that year.
The mainline of Interstate 4 was completed in 1966.
