Moving I-4 Forward: what changes, exit by exit

Is there a map of Moving I-4 Forward?

Yes. FDOT publishes a program overview map and a map for each of its projects on its own program site, movingi4forward.com; the overview map is reproduced on this page, and each project page carries its own (FDOT, Program Overview).

FDOT describes the program in one sentence: “FDOT is planning a series of projects called Moving I-4 Forward to improve I-4 from west of U.S. 27 to east of State Road (S.R.) 536.” On FDOT's list of I-4 exits, the interchanges at those two ends are Exit 55, US 27, and Exit 67, SR 536 (FDOT, Program Overview; FDOT, Interstate Exit Numbers for I-4).

It is made of parts: “The Moving I-4 Forward Program consists of five main projects plus an initial phase called the Accelerated Start that included two additional components to jump-start future construction.” The pair of lanes built in that first phase is open. For each of the five projects FDOT's map prints a construction year, 2025 or 2026, and no page of the program prints a year in which a project ends (FDOT, Program Overview).

What the program builds, in FDOT's words

The finished road, in FDOT's words: “By widening I-4 from six lanes to up to 12 lanes, eight general use lanes (four lanes in each direction) and four express lanes (for future use), FDOT will provide much-needed congestion relief.” FDOT calls the corridor “this 14-mile stretch of highway” (FDOT, Program Overview).

“Up to” matters, because the lanes are not the same from end to end. FDOT's own project pages give three general-use lanes in each direction between World Drive and U.S. 192, four between C.R. 532 and World Drive, and four east of U.S. 27 with three west of it, each with two express lanes in each direction (FDOT, Project 1; FDOT, Project 2; FDOT, Project 3). An FDOT release of April 3, 2024 described the same work as widening “14.7 miles of I-4 in Osceola and Polk counties from six to ten lanes”, and one of April 14, 2025 as “two new express lanes and one general use lane in each direction” along a “14-mile corridor from U.S. 27 in Polk County to S.R. 536 in Orange County” (FDOT, release of April 3, 2024; FDOT, release of April 14, 2025). This page gives each figure with the page that prints it and does not choose between them.

The money comes from a state program. FDOT's home page for the work says: “Through the Moving Florida Forward Infrastructure Initiative, FDOT is accelerating a series of projects in Central Florida to add two new Express Lanes in each direction along Interstate 4 (I-4) from west of U.S. 27 in Polk County to east of World Center Drive, State Road (S.R.) 536 in Orange County.” It says the projects “will deliver much-needed congestion relief 10 to 20 years ahead of the original schedule” (FDOT, Moving I-4 Forward home page). Of the initiative itself, FDOT writes: “During the 2023 Legislative Session, Governor DeSantis proposed, and the Florida Legislature then passed the Moving Florida Forward Infrastructure Initiative.” (FDOT, Moving Florida Forward).

What is open now

One part is open. FDOT: “To provide motorists with immediate congestion relief, FDOT advanced the construction of two new congestion relief lanes along Interstate 4 (I-4) from east of U.S. 27 to World Drive. Construction of the congestion relief lanes is complete and opened to traffic.” (FDOT, Accelerated Start). The two lanes are one in each direction: “One additional lane in each direction is now fully opened to traffic.” (FDOT, Moving I-4 Forward home page).

FDOT's release of April 14, 2025 gave the date in advance: “The new lanes, one additional lane in each direction of I-4 from U.S. 27 in Polk County to World Drive in Osceola County, will be open for use beginning the week of April 28.” Its home page says of the same work: “This work that was anticipated for completion at the end of 2025, is now complete - eight months AHEAD OF SCHEDULE.” (FDOT, release of April 14, 2025; FDOT, Moving I-4 Forward home page).

The first phase is not over. “Additional work in the Accelerated Start phase will add the pavement to expand I-4 to the full width to accommodate up to 12 total lanes at the ChampionsGate Boulevard (C.R. 532) and World Drive interchanges.” (FDOT, Accelerated Start).

What each FDOT map prints

Each part of the program has its own map on FDOT's site, and each map carries a panel of facts that the text of its page does not repeat: the county, the length, a construction year and FDOT's Financial Project ID. The table reproduces those panels as printed. The map for the first phase also prints a schedule: “Early 2025: Groundbreaking”, “Spring 2025: Congestion Relief Lanes Open” and “2026: Accelerated Start Complete”.

On two points FDOT prints two things. The Project 5 map gives the Poinciana Connector as 3.5 miles, and the Project 5 page says “Design is still underway on the 2.6-mile road that will extend into Osceola and Polk counties.” And FDOT writes the east end of the first phase's lanes both ways: the body of the Accelerated Start page says “from east of U.S. 27 to World Drive”, while its map, and a line FDOT repeats across the program's pages, say east of World Drive: “Accelerated start will add congestion relief lanes in each direction from east of U.S. 27 to east of World Drive”. This page gives each as FDOT prints it.

Exit by exit, west to east

The table follows I-4 from west to east. The exit numbers and the interchange names are the ones on FDOT's own list of I-4 exits; the limits of each project are the ones in the title of its FDOT page. A project's limits are written as “east of” or “west of” an interchange, so an interchange where one project ends and the next begins is given with both.

What FDOT does not print

FDOT's pages for the program print no total cost, and no date on which the program or any of its five projects ends. The program overview, the home page, the five project pages and the Accelerated Start page were read for this guide on October 13, 2026, text and maps. What they do print is a construction year, on each project's map: 2025 for Projects 1, 2 and 5, and 2026 for Projects 3 and 4; and, on the first phase's map, an end for that phase: “2026: Accelerated Start Complete”. Figures for the program's cost and its end circulate in news reports; this page repeats none of them.

FDOT's District Five site, CFLRoads, adds a phase and, for one record, a cost. It lists as in the design phase a widening of 4.022 miles from west of U.S. 27 to west of C.R. 532, and one of 7.885 miles from west of C.R. 532 to east of Osceola Parkway (CFLRoads, 201210-9; CFLRoads, 431456-3). It lists a third, also in design, of 5.7 miles from east of Osceola Parkway to Central Florida Parkway, with an estimated construction cost of $515 Million (CFLRoads, 431456-2). All three records name movingi4forward.com as the website for the entire project. The numbers 431456-3 and 431456-2 are also the ones on the Project 2 and Project 4 maps, for 3.1 and 2.1 miles. FDOT's two sites describe the same project numbers with different limits; this page gives each as printed and does not reconcile them.

Earlier FDOT releases did give dates, and they are older than the pages above. On September 27, 2023 FDOT wrote of I-4 from west of U.S. 27 to west of C.R. 532: “Construction starts in Fall 2026.” On April 3, 2024 it wrote that the Poinciana Parkway Connector would be phased “by incorporating 65% of the work into a portion of these I-4 projects that will break ground later this year and the remaining work in 2028” (FDOT, release of September 27, 2023; FDOT, release of April 3, 2024). A date in a release is what FDOT expected on the day of the release.

Closures: where FDOT posts them

For a driver the daily question is closures, and FDOT posts them. Its Construction Updates page lists each closure with its date and hours and carries a map of lane closures and detours; on the day this guide was written it listed overnight closures of I-4 eastbound lanes from ChampionsGate Boulevard (C.R. 532) to S.R. 429 and of ramps at S.R. 429 (FDOT, Construction Updates). The list changes week by week, so the page is the place to look, not this guide.

East of S.R. 536: I-4 Beyond the Ultimate

East of S.R. 536, FDOT's site for I-4 Beyond the Ultimate and its CFLRoads pages describe further work, at different stages: the ramp at S.R. 528 is finished, the interchanges at S.R. 535 and at Sand Lake Road are in construction with an estimated completion of late 2027, and the widening from Central Florida Parkway to Kirkman Road is in design (CFLRoads, 448915-1; CFLRoads, 448914-1; CFLRoads, 444315-1; CFLRoads, 242484-7). Of Sand Lake Road, FDOT writes: “The I-4 and Sand Lake Road interchange will continue to undergo improvements until anticipated completion in 2027.” (FDOT, I-4 Beyond the Ultimate). West of the program, in Polk County, FDOT's District One has interchange improvements at S.R. 33 in construction: the current phase started in Early 2025, and its estimated completion is Early 2029 (SWFLRoads, 430185-2).

What this tells a buyer, and what it does not

What FDOT's pages establish for someone choosing a home near this stretch of I-4 is limited and concrete: which interchange a project touches, what is open today, and the year FDOT's map gives for construction. They do not say when the express lanes will open, and nothing on them is a statement about home values. This guide makes none.
