'''Interstate&nbsp;4''' ('''I-4''') is an [[Interstate Highway System|Interstate Highway]] located entirely within the US state of [[Florida]], maintained by the [[Florida Department of Transportation]] (FDOT). Spanning {{convert|132.30|mi|km}} along a generally southwest–northeast axis, I-4 is entirely [[Concurrency (road)|concurrent]] with '''State Road&nbsp;400''' ('''SR&nbsp;400'''). In the west, I-4 begins at an interchange with [[Interstate 275 (Florida)|I-275]] in [[Tampa, Florida|Tampa]]. I-4 intersects with several major [[Controlled-access highway|expressways]] as it traverses [[Central Florida]], including [[U.S. Route 41 in Florida|US Highway&nbsp;41]] (US&nbsp;41) in Tampa; [[U.S. Route 301 in Florida|US&nbsp;301]] near [[Riverview, Florida|Riverview]]; [[Interstate 75 in Florida|I-75]] near [[Brandon, Florida|Brandon]]; [[U.S. Route 98 in Florida|US&nbsp;98]] in [[Lakeland, Florida|Lakeland]]; [[U.S. Route 27 in Florida|US&nbsp;27]] in unincorporated [[Davenport, Florida|Davenport]]; [[U.S. Route 192|US&nbsp;192]] in [[Celebration, Florida|Celebration]]; [[Florida's Turnpike]] in [[Orlando, Florida|Orlando]]; and [[U.S. Route 17 in Florida|US&nbsp;17]] and [[U.S. Route 92|US&nbsp;92]] in multiple junctions. In the east, I-4 ends at an interchange with [[Interstate 95 in Florida|I-95]] in [[Daytona Beach, Florida|Daytona Beach]], while SR&nbsp;400 continues for roughly another {{convert|4|mi|spell=in|km}} and ends at an intersection with [[U.S. Route 1 in Florida|US&nbsp;1]] on the city line of Daytona Beach and [[South Daytona, Florida|South Daytona]].

Construction on I-4 began in 1958; the first segment opened in 1959, and the entire highway was completed in 1965.<ref>{{cite web |url = http://i4ultimate.com/project-info/overview/ |title = Overview: I-4 Ultimate |publisher = Florida Department of Transportation |access-date = May 29, 2017 |archive-date = June 5, 2017 |archive-url = https://web.archive.org/web/20170605055923/http://i4ultimate.com/project-info/overview/ |url-status = dead }}</ref> The "I-4 Ultimate" project oversaw the construction of [[High-occupancy toll lane|variable-toll express lane]]s and numerous redevelopments through the {{convert|21|mi|km|adj=on}} stretch of highway extending from [[Kirkman Road]] (SR&nbsp;435; exit&nbsp;75) in Orlando to [[Florida State Road 434|SR&nbsp;434]] (exit&nbsp;94) in [[Longwood, Florida|Longwood]]. The project broke ground in 2015, and the express lanes opened to traffic on February 26, 2022.

I-4 maintains a diagonal, northeast–southwest route for much of its length, although it is signed east–west. It roughly follows the original path of the [[South Florida Railroad]] built by [[Henry B. Plant]] in 1884.

The highway starts its eastward journey at an interchange with I-275—known as "Malfunction Junction"—near [[Downtown Tampa]] and is the starting point for [[milemarker]]s and [[exit number]]s (which are [[Mileage-based exit numbering|mileage-based]]). Just east of Malfunction Junction, I-4 passes along the north side of Tampa's [[Ybor City]] district, where a mile-long ({{Convert|1|mi|km|disp=output only}}) [[I-4/Selmon Expressway Connector|connector]] links to the [[Lee Roy Selmon Expressway]] (SR&nbsp;618) and [[Port Tampa Bay]].<!-- The connector has ramps onto SR618, but also ramps directly to surface streets near the port (intended for trucks and signed to the port) --> I-4 continues east past the [[Florida State Fairgrounds]] toward a [[turbine interchange]] (uncommon in the US)<ref>{{cite web |last1 = Boniface |first1 = Russell |title = Interchange |url = http://www.asce.org/cemagazine/Article.aspx?id=25769803777#.U_KcMmNrUhw |work = CE Magazine |publisher = American Society of Civil Engineers |access-date = August 19, 2014 |date = November 1, 2001 |quote = The turbine design, which is rare in the United States, is a first of its kind in North Carolina; another notable example exists at the interchange of I-4 and I-75 in Tampa, Florida. |url-status = dead |archive-url = https://web.archive.org/web/20140819090758/http://www.asce.org/cemagazine/Article.aspx?id=25769803777 |archive-date = August 19, 2014 }}</ref> with I-75.

After passing near the eastern suburbs of [[Hillsborough County, Florida|Hillsborough County]]—including [[Brandon, Florida|Brandon]] and [[Plant City, Florida|Plant City]]—it enters [[Polk County, Florida|Polk County]], where I-4 crosses along the north side of [[Lakeland, Florida|Lakeland]]. The [[Polk Parkway]] (SR&nbsp;570) forms a semi-loop through Lakeland's southern suburbs and returns to I-4 at the [[Florida Polytechnic University]] campus, near [[Polk City, Florida|Polk City]];<!-- The junction is sort of in the middle of nowhere...the university campus is very noticeable on the corner of the intersection while Polk City (only about 1000 residents) is a tiny town and basically just an exit with a couple gas stations & truck stop. --> it does not serve as a [[Bypass (road)|bypass route]] for I-4 traffic.

Additionally, an exit to World Drive (signed as just "Disney World") runs north as a limited-access highway into [[Walt Disney World]] and an electric [[Mickey pylon|pylon]] in the shape of [[Mickey Mouse]] can be seen on the southwest corner of the intersection. The single Central Florida GreeneWay/World Drive exit (exit&nbsp;62) also marks an abrupt change from rural to suburban/urban landscape. The highway passes beside [[Celebration, Florida|Celebration]] and [[Kissimmee, Florida|Kissimmee]] on the east side and Walt Disney World (not visible) on the west side.<!-- Lake Buena Vista is basically a municipality comprising Disney World with no real population to speak of. -->

It enters [[Orange County, Florida|Orange County]], passes through Walt Disney World and by [[SeaWorld Orlando]] and [[Universal Orlando]], and intersects all of the area's major [[toll road]]s, including the [[Beachline Expressway]] (SR&nbsp;528), [[Florida's Turnpike]], and the [[East–West Expressway (Orlando)|East–West Expressway]] (SR&nbsp;408). Orlando's main [[tourist strip]]—[[International Drive]]—runs parallel and no more than {{Convert|1.5|mi|km}} from I-4 between Kissimmee and Florida's Turnpike. Between Michigan Street and Kaley Avenue (about mile&nbsp;81), I-4 turns due north (while still being signed east–west), heading past [[Downtown Orlando]] and its northern suburbs. A {{convert|21|mi|km|adj=on}} section of I-4 from west of SR&nbsp;435 to east of SR&nbsp;434 (miles&nbsp;75–96) underwent a $2.3-billion reconstruction, and was completed on February 26, 2022.

==History==
[[File:Tampa-St. Petersburg, Florida 1955 Yellow Book.jpg|thumb|left|The original plans called for I-4 to extend to St. Petersburg]]
I-4 was one of the first Interstate Highways to be constructed in Florida, with the first section opening between Plant City and [[Lakeland, Florida|Lakeland]] in 1959. By early 1960, the [[Howard Frankland Bridge]] was opened to traffic, as well as the segment from the Hillsborough Avenue/US&nbsp;301 junction in Tampa to Plant City. The stretch from Lake Monroe to [[Lake Helen, Florida|Lake Helen]], including the original [[St. Johns River Veterans Memorial Bridge]] also opened during that period. The segment from Tampa to Orlando was complete by 1962.<ref>{{cite news |title = Highways to Your Vacationland |url = https://news.google.com/newspapers?id=GjtQAAAAIBAJ&dq=history%20florida%20state%20route%2010%20-wikipedia%20-trulia&pg=4304%2C467553 |department = All Florida and TV Week Magazine |work = The Evening Independent |location = Jacksonville |date = June 3, 1962 }}</ref> By the mid-1960s, several segments were already complete, including Malfunction Junction in Tampa and parts of I-4 through Orlando.

The entire Interstate Highway was completed by the late 1960s; however, the western terminus was truncated to Malfunction Junction in 1971 when I-75 was extended over the Howard Frankland Bridge. Eventually, that stretch was again redesignated to become part of I-275.<ref>{{cite web |url = http://www.moderncities.com/article/2016-oct-changing-tampa-then-and-now/page/1 |title = Changing Tampa: Then and Now |publisher = Modern Cities |date = October 2, 2016 |access-date = May 29, 2017 |archive-date = March 3, 2017 |archive-url = https://web.archive.org/web/20170303102716/http://www.moderncities.com/article/2016-oct-changing-tampa-then-and-now/page/1 |url-status = dead }}</ref>

In maps and atlases dating to the 1950s, 1960s, and 1970s, the Tampa–St. Petersburg section of I-4/I-275 was marked as the Tampa Expressway. The Orlando segment was marked as the Orlando Expressway. Both names have since faded from maps.

Although many post-1970 interchanges along I-4 were constructed before the recent widening projects, they were designed with I-4 expansion in mind. In other words, there is enough room available to widen I-4 to up to 10&nbsp;lanes without extensively modifying the interchanges. Some of these interchanges include the I-75 stack (constructed in the 1980s) and several interchanges serving the Walt Disney World Resort (constructed in the late 1980s and early 1990s).

In 2002, I-4, along with most of Florida's Interstates, switched over from a [[sequential exit numbering]] system to a [[mileage-based exit numbering]] system.<ref>{{cite web |author = Staff |url = http://www.dot.state.fl.us/TrafficOperations/Operations/exitnumb/i_4.shtm |title = Florida's Interstate Exit Numbers- I-4 |publisher = Florida Department of Transportation |access-date = November 18, 2010 |url-status = dead |archive-url = https://web.archive.org/web/20101113130335/http://www.dot.state.fl.us/trafficoperations/Operations/exitnumb/i_4.shtm |archive-date = November 13, 2010 |df = mdy-all }}</ref>

A section of I-4 between Daytona Beach and Orlando, called the "dead zone", is rumored to be haunted.<ref>{{cite news |url = http://www.local6.com/news/13273890/detail.html |title = Ghostly Images Seen, Photographed on 'Deadly' Stretch of I-4 |publisher = [[WKMG-TV]] |location = Orlando |url-status = dead |archive-url = https://web.archive.org/web/20080914053758/http://www.local6.com/news/13273890/detail.html |archive-date = September 14, 2008 }}</ref> In 2010, the East Central Florida Regional Planning Council (ECFRPC), using [[geographic information system]] technology, performed an analysis to determine if this identified zone had an increased fatality rate related to crashes. The analysis, which compared this section of I-4 to several other dangerous I-4 sections, found that, while the dead zone area did not have the highest accident or fatality rate, it did identify that the percentage of fatality to accident was significantly higher in this location. Multiple hurricanes, including three category 4 hurricanes ([[Hurricane Donna|Donna]], [[Hurricane Charley|Charley]], and [[Hurricane Ian|Ian]]) have also passed over that area.<ref>{{cite news |last1 = Boedeker |first1 = Hal |title = I-4 Dead Zone: Scary legend grows |url = https://www.orlandosentinel.com/entertainment/tv-guy/os-i4-dead-zone-scary-legend-grows-20141023-post.html |access-date = September 28, 2022 |work = orlandosentinel.com }}</ref>

The median of I-4 between Tampa and Orlando was slated to be used for the [[Florida High-Speed Corridor]] line between those cities. As a result of a state constitutional amendment to build a high-speed rail system between its five largest cities passed by voters in 2000, construction projects on I-4 included a wide median to accommodate a high-speed rail line. The high-speed rail project was canceled in 2004 but revived again in 2009. In 2010, the federal government awarded Florida over $2&nbsp;billion (equivalent to ${{Formatprice|{{inflation|US-GDP|2000000000|2010}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}})—nearly the entire projected construction cost—to build the line, with work on the project to begin in 2011 and be completed by 2014. However, Governor [[Rick Scott]]'s rejection of the funding ended the project.<ref>{{cite news |url = https://www.reuters.com/article/florida-rail-idUSN1629082420110216 |work = Reuters |title = UPDATE 1-Florida governor rejects US high-speed rail funds |date = February 16, 2011 |access-date = July 8, 2017 |archive-date = September 24, 2015 |archive-url = https://web.archive.org/web/20150924151223/http://www.reuters.com/article/2011/02/16/florida-rail-idUSN1629082420110216 |url-status = live }}</ref>

On January 9, 2008, 70&nbsp;vehicles were involved in a large pileup on I-4 near [[Polk City, Florida|Polk City]]. The pileup was caused by an unexpected thick morning fog that was mixed with a scheduled—and approved—environmental burn by the [[Florida Fish and Wildlife Conservation Commission]]. The fog drifted across I-4, mixing with the smoke and reducing visibility to near-zero conditions. Four people were killed and 38 were injured. The section of I-4 did not reopen until the next day, January 10.<ref>{{cite news |url = http://www.wise4u.com/interstate-4-deadly-collisions-2008/ |title = Interstate 4 Deadly Collisions |date = January 10, 2008 |archive-url = https://web.archive.org/web/20141213231721/http://www.wise4u.com/interstate-4-deadly-collisions-2008/ |archive-date = December 13, 2014 |access-date = April 27, 2018 |url-status = usurped }}</ref>

The I-4/I-275 interchange (Malfunction Junction) was rebuilt from 2002 to 2007,<ref>{{cite web |author = Staff |url = http://www.mytbi.com/projects/projectinfo.asp?projectID=44&RoadID=2 |work = Tampa Bay Interstates |publisher = Florida Department of Transportation |title = Construction Projects: I-4/I-275 Interchange (operational improvements, completed December 2006) |access-date = November 27, 2011 |url-status = dead |archive-url = https://web.archive.org/web/20110927125926/http://www.mytbi.com/projects/projectinfo.asp?projectID=44&RoadID=2 |archive-date = September 27, 2011 |df = mdy-all }}</ref> and I-4 has been widened from four to six lanes (with eight lanes in certain segments).

Eastbound I-4 shifted to its new, permanent alignment between Malfunction Junction and 50th Street on August 8, 2006. The new alignment includes a right-lane ramp exit/entry at the 22nd Street/21st Street Interchange (the previous left-lane configuration was causing hazardous conditions to commuters since its opening in 2005). On August 11, 2006, a fourth lane opened on eastbound I-4 between the downtown junction and 50th Street (led in by a newly opened third lane on the eastbound I-4 ramp from northbound I-275). And, on August 18, the new westbound alignment, just west of 50th Street, opened. The newly opened lanes will improve flow throughout the interchange. The 50th Street overpass, however, would not be complete until late 2007.<ref>{{cite web |author = Staff |work = Tampa Bay Interstates |publisher = Florida Department of Transportation |date = August 8, 2006 |url = http://www.i4.org/content/users/details.asp?newsid=2051 |title = Eastbound I-4 in new alignment |url-status = dead |archive-url = https://web.archive.org/web/20070927181057/http://www.i4.org/content/users/details.asp?newsid=2051 |archive-date = September 27, 2007 }}</ref><ref>{{cite news |location = St. Petersburg |publisher = [[WTSP]]-TV |url = http://www.wtsp.com/news/local/article.aspx?storyid=37001 |archive-url = https://archive.today/20130209165551/http://www.wtsp.com/news/local/article.aspx?storyid=37001 |url-status = dead |archive-date = February 9, 2013 |title = Eastbound I-4 Traffic: New Lanes, New Exit through Ybor City |date = August 7, 2006 }}</ref><ref>{{cite news |location = St. Petersburg |publisher = WTSP-TV |url = http://www.tampabays10.com/news/local/article.aspx?storyid=37267&s=newsletter |title = New I-4 Lanes Help Drivers Get to Concert Early |date = August 10, 2006 }}{{dead link|date=June 2016|bot=medic}}{{cbignore|bot=medic}}</ref><ref>{{cite press release |author = Staff |work = Tampa Bay Interstates |url = http://www.mytbi.com/content/users/details.asp?newsid=2055 |title = New Eastbound I-4 Lane Open! |publisher = Florida Department of Transportation |date = August 8, 2006 |url-status = dead |archive-url = https://web.archive.org/web/20070926220826/http://www.mytbi.com/content/users/details.asp?newsid=2055 |archive-date = September 26, 2007 }}</ref> Also, the eastbound I-4 exit ramp to Columbus Drive/50th Street is situated to the left-hand side of the highway (as opposed to its former right-hand side exit).

In Tampa, the exit to 40th Street ([[Florida State Road 569|SR&nbsp;569]]), exit&nbsp;2, was closed and demolished in late 2005 due to the ongoing reconstruction of I-4 and to accommodate [[I-4/Selmon Expressway Connector|a proposed connector highway]] with the [[Lee Roy Selmon Expressway]].<ref>{{cite web |author = Staff |work = Tampa Bay Interstates |url = http://www.mytbi.com/urs/content/Design/I4-CrosstownConnector/index.asp |title = I-4/Crosstown Connector Project Page |publisher = Florida Department of Transportation |url-status = dead |archive-url = https://web.archive.org/web/20081014034357/http://www.mytbi.com/urs/content/Design/I4-CrosstownConnector/index.asp |archive-date = October 14, 2008 }}</ref>

The interchange with what is today I-75 was constructed in the early 1980s.

===Greater Orlando===
[[File:FL 2 I4 FHWA 62 63 75280 3417.jpg|thumb|right|Parking lots under I-4 in Downtown Orlando, 1962]]
As Orlando grew in the 1970s and 1980s, traffic became a growing concern, especially after the construction of the original interchange with the [[East–West Expressway (Orlando)|East–West Expressway]] in 1973, which proved to become a principal bottleneck. The term "highway hostages" was coined in the 1980s to describe people stuck in long commutes to and from Orlando on I-4.<ref>{{cite news |last1 = Kunerth |first1 = Jeff |title = Atlanta's Road Work Nearly Finished - For Now |url = https://www.orlandosentinel.com/news/os-xpm-1989-07-03-8907030217-story.html |access-date = August 7, 2021 |work = Orlando Sentinel |date = July 3, 1989 }}</ref>

In the early-to-mid-1990s, several interchanges near Kissimmee were constructed or upgraded to accommodate increasing traffic going to and from Walt Disney World. However, I-4's mainlanes were not widened in the process. Around the same time, SR&nbsp;417 was extended to I-4.{{Citation needed|date=March 2010}} Improvements to the US&nbsp;192 junction were completed in 2007.<ref>{{cite web |author = Staff |url = http://www.trans4mation.org/?id=169 |archive-url = https://web.archive.org/web/20070503151428/http://www.trans4mation.org/?id=169 |url-status = dead |archive-date = May 3, 2007 |title = US&nbsp;192 Interchange_Project Overview |work = Trans4mation |publisher = Florida Department of Transportation |access-date = November 27, 2011 }}</ref>

The [[St. Johns River Veterans Memorial Bridge]], a two-span, six-lane replacement to the original four-lane bridge over the [[St. Johns River]] northeast of Orlando, was completed in 2004.

During the early 2000s, [[toll road|tolled]] [[High-occupancy toll lane|express lanes]] were being planned in the Orlando area as a traffic congestion relief technique for [[rush-hour]] commuters. The name for them was to be Xpress 400, numbered after the state road designation for I-4. The express lanes were slated to extend from [[Universal Orlando]], east to SR&nbsp;434 in [[Longwood, Florida|Longwood]], and tolls were to be [[electronic toll collection|collected electronically]] via transponders like [[SunPass]] and [[Central Florida Expressway Authority]]'s [[E-PASS]], with prices dependent on the congestion of the eight mainlanes. However, the project was effectively banned by the passage of the [[Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users]] federal transportation bill in 2005, introduced by US Representative [[John Mica]]. The plan for tolled express lanes is now moving forward as part of the $2.3-billion I-4 Ultimate project.

Interim improvements to the interchange at [[Florida State Road 408|SR&nbsp;408]] were completed at the end of 2008.<ref>{{cite web |author = Staff |url = http://www.trans4mation.org/?id=166 |archive-url = https://web.archive.org/web/20070218021123/http://www.trans4mation.org/?id=166 |url-status = dead |archive-date = February 18, 2007 |title = I-4 Trans4mation (FSTR 408 Interchange Project) |work = Trans4mation |publisher = Florida Department of Transportation |access-date = November 27, 2011 }}</ref> The eastbound exit to Robinson Street ([[Florida State Road 526|SR&nbsp;526]]) permanently closed on April 25, 2006, to make way for construction of the new eastbound onramp from [[Florida State Road 408|SR&nbsp;408]].<ref>{{cite news |publisher = [[Central Florida News 13]] |location = Orlando |url = http://cfn13.com/StoryHeadline.aspx?id=15141 |title = On the Move |date = April 25, 2006 |url-status = dead |archive-url = https://web.archive.org/web/20060524030747/http://www.cfn13.com/StoryHeadline.aspx?id=15141 |archive-date = May 24, 2006 }}</ref> The westbound offramp to Gore Street was permanently closed in the same project on November 2, 2008.

The construction for 2 additional lanes, one in each direction between U.S. 27 and World Drive began in late 2024 and was completed by April 2025, 8 months ahead of schedule and opened for traffic the last week of April delivering congestion relief to one of state's most congested sections of roadway.<ref>{{Cite web |title = Governor Ron DeSantis Announces Early Completion of Congestion Relief Lanes on I-4 |url = https://www.fdot.gov/info/co/news/2025/04142025 |access-date = June 9, 2025 |website = www.fdot.gov |language = en-US }}</ref>

==Future==

===I-4 Beyond the Ultimate===
I-4 Beyond the Ultimate, which includes proposed extensions of the I-4 Express toll lanes, both southwest and northeast of the I-4 Ultimate project, are being considered. In 2013, FDOT initiated a study to reevaluate previous feasibility studies, made between 1998 and 2005, in which the addition of HOV or express toll lanes were considered.<ref name="I-4 BU original documents">{{cite web |title = Original Documents |url = http://www.i4express.com/original_documents.shtm |website = Interstate 4 Beyond the Ultimate |publisher = Florida Department of Transportation |access-date = February 19, 2015 |archive-date = February 19, 2015 |archive-url = https://web.archive.org/web/20150219135644/http://www.i4express.com/original_documents.shtm |url-status = dead }}</ref><ref name="I-4 BU FAQs" /> The extensions cover approximately {{convert|40|mi|km}} of I-4 through Greater Orlando. Southwest of the I-4 Ultimate, the study is examining an extension through Osceola County to US&nbsp;27 in Polk County. Northeast of the I-4 Ultimate, the study is examining an extension through Seminole County to SR&nbsp;472 in Volusia County.<ref name="I-4 BU FAQs">{{cite web |title = Frequently Asked Questions |url = http://www.i4express.com/project_faq.shtm |website = Interstate 4 Beyond the Ultimate |publisher = Florida Department of Transportation |access-date = February 19, 2015 |archive-date = February 15, 2015 |archive-url = https://web.archive.org/web/20150215211851/http://i4express.com/project_faq.shtm |url-status = dead }}</ref>

In addition to these express lane extensions, many interchanges will be reconstructed as part of the project. Some of these reconstructed interchanges will be converted to [[diverging diamond interchange]]s, which are proposed at both [[County Road 532 (Osceola County, Florida)|CR&nbsp;532]] (exit&nbsp;58; implemented on July 10, 2022) and [[Florida State Road 482|SR&nbsp;482]] (exit&nbsp;74A; implemented on March 9, 2024). A brand new interchange at Daryl Carter Parkway is also proposed to be a diverging diamond.

Unlike I-4 Ultimate, where the {{convert|21|mi|km}} encompassed by that project were constructed at once, the {{convert|40|mi|km}} encompassed by I-4 Beyond the Ultimate will be constructed in phases.<ref>{{Cite web |title = Project Info & Map: Find out what's happening in your area. |url = https://i4beyond.com/project-info-map/ |access-date = October 2, 2022 |website = I-4 Beyond the Ultimate |language = en }}</ref>

===Additional express lanes===
Express toll lanes are also being considered for I-4 in the [[Tampa Bay area]]. In January 2015, FDOT unveiled its master plan for a system of express toll lanes—dubbed Tampa Bay Express (TBX)—on I-4, I-75, and I-275 and began public meetings for community input.<ref name="TBX first press release">{{cite press release |first = Kris |last = Carson |title = FDOT Media Advisory |url = http://www.tampabayexpress.com/wp-content/uploads/2015/01/TBX-media-advisory.pdf |website = Tampa Bay Express |publisher = Florida Department of Transportation |access-date = February 19, 2015 |date = January 16, 2015 |archive-date = February 19, 2015 |archive-url = https://web.archive.org/web/20150219150049/http://www.tampabayexpress.com/wp-content/uploads/2015/01/TBX-media-advisory.pdf |url-status = dead }}</ref> On I-4, these lanes would extend approximately {{convert|26|mi|km}} from I-275 to west of the Polk Parkway (SR&nbsp;570). At the junction with I-275, the initial concept alignment calls for a direct connection between the express toll lanes of both highways.<!-- but not at I-75, see http://www.tampabayexpress.com/wp-content/uploads/2015/02/MP-8-2-of-3-I-75-S-OF-US-301-TO-N-OF-BBD-BLVD.compressed.pdf --><ref name="TBX Malfunction Junction concept map">{{cite map |title = Master Plan Project: I-275 from South of SR&nbsp;60 to North of MLK Boulevard (3) |url = http://www.tampabayexpress.com/wp-content/uploads/2015/02/MP-3-3-of-4-I-275-S-OF-SR&nbsp;60-TO-N-OF-MLK.pdf |via = ''Tampa Bay Express'' |publisher = Florida Department of Transportation |access-date = February 19, 2015 |format = PDF |date = January 2015 |archive-date = February 19, 2015 |archive-url = https://web.archive.org/web/20150219143021/http://www.tampabayexpress.com/wp-content/uploads/2015/02/MP-3-3-of-4-I-275-S-OF-SR&nbsp;60-TO-N-OF-MLK.pdf |url-status = dead }}</ref> Express bus lanes for regional service and a long-distance bus service were studied for inclusion in the plan.

'''State Road&nbsp;400''' ('''SR&nbsp;400''') is an [[unsigned highway]] while running concurrently with I-4 from their shared western terminus at I-275 in Tampa through the last eastbound exit before the eastern terminus of I-4, at I-95 in Daytona Beach.

In the [[2004 US presidential election in Florida]], the '''I-4 corridor''', a commonly used term to refer to the counties in which I-4 runs through and a site of significant population growth, was a focus of political activity within the [[swing state]]. Communities along the I-4 corridor were perceived by both major political parties as having higher proportions of [[undecided voter]]s as compared to more [[Republican Party (United States)|Republican]]- or [[Democratic Party (United States)|Democratic]]-leaning portions of the state. It played an equally key role in the [[2008 US presidential election in Florida]] but, whereas the corridor had voted heavily for [[George W. Bush]] in 2004, which helped Bush win the state, in 2008, it swung behind Democratic candidate [[Barack Obama]], helping Obama win Florida.<ref>{{cite news |publisher = [[CNN]] |url = http://www.cnn.com/2004/ALLPOLITICS/10/11/campaign.florida.reut/index.html |title = Candidates Eye Voters on Florida's I-4 |date = October 11, 2004 }}</ref>

Between 1996 and 2012, the I-4 corridor voted for the statewide winner. However, in the [[2016 United States presidential election in Florida|2016]] and [[2020 United States presidential election in Florida|2020]] elections, Republican [[Donald Trump]] carried the state without winning the region. The Republicans carried the region three times while the Democrats carried the region five times in the past eight presidential elections. Republicans [[George H. W. Bush]] and George W. Bush won more votes than other candidates in 1992, 2000, and 2004, while Democrats [[Bill Clinton]], Barack Obama, [[Hillary Clinton]], and [[Joe Biden]] captured the region's vote total in the elections of [[1996 United States presidential election|1996]], 2008, [[2012 United States presidential election|2012]], 2016, and 2020.

Trump again won the [[2024 United States presidential election in Florida]]. [[WKMG-TV]] reported that because of the size of his victory of more than 13%, Florida was no longer a swing state. Noting that Trump had won all nine central Florida counties except Orange County, the station said that "the days of the I-4 corridor being a thing [are] no more".<ref name="wkmg20241105">{{Cite AV media |url=https://www.youtube.com/watch?v=vCYE2ozMOMs |title=Trump wins Florida in big way |date=2024-11-05 |publisher=WKMG News 6 ClickOrlando |access-date=2024-11-25 |via=YouTube}}</ref>
