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). This exit shift went into effect in spring 2006 and is part of the new, permanent Interstate configuration.

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.
