===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>

As part of the "Moving Florida Forward" initiative, construction of I-4 widening between Championsgate and [[Osceola Parkway]] will add additional lanes on this 15-mile segment, which is expected to begin construction in late 2024.<ref>{{Cite web |date=2024-04-03 |title=Construction to begin this year for I-4 widening project, DeSantis says |url=https://www.wfla.com/news/politics/gov-desantis-expected-to-sign-transportation-bill-in-polk-city/ |access-date=2024-04-06 |website=WFLA |language=en-US}}</ref>
