Though there is no specific date for completion, long-term plans call for the two segments of I-99 to be connected via [[U.S. Route 220 in Pennsylvania|US 220]] from [[Bellefonte, Pennsylvania|Bellefonte]] to [[Williamsport, Pennsylvania|Williamsport]], running concurrent with [[Interstate 80 in Pennsylvania|I-80]] as US 220 currently does, and continue northward along [[U.S. Route 15 in Pennsylvania|US 15]] from Williamsport to the New York border. The entire portion of US 15 involved has been upgraded to [[Interstate Highway standards]] in anticipation of the I-99 designation, but some sections of US 220 still require upgrades, primarily in the vicinity of both interchanges with I-80 and between [[Jersey Shore, Pennsylvania|Jersey Shore]] and [[Linden, Pennsylvania|Linden]]. Signs have been erected along the present US 220 and US 15 between Bellefonte and Corning marking the route as the "Future I-99 Corridor".<ref>{{Cite web|url=http://www.m-plex.com/roads/pamplex/mp_i99_us15.html|title=US 15/Future I-99 Multiplex - Central PA/MD Roads|website=www.m-plex.com|access-date=2019-01-13}}</ref> Some of this section of road has also received exit number designations.

PennDOT has plans to build a high-speed interchange connecting I-99 to I-80 near [[Bellefonte, Pennsylvania|Bellefonte]]. The new interchange will eliminate local access between [[Pennsylvania Route 26|PA&nbsp;26]] (Jacksonville Road) and I-80, which will be provided by a new exit {{Convert|2|mi|km|spell=in}} to the east. The first phase of the project built the local access interchange between PA&nbsp;26 and I-80. Construction on the local access interchange began on July 27, 2020. The local access interchange was opened to traffic on November 10, 2022, with a ribbon-cutting ceremony held.<ref name="Phases">{{cite news |last1=Sinderson |first1=Gary |title=First phase of Interstate 99/I-80 interchange project complete |url=https://wjactv.com/news/local/first-phase-of-interstate-99i-80-interchange-project-complete |access-date=5 May 2023 |work=WJAC |date=10 November 2022 |language=en}}</ref><ref>{{cite news|last=Kines|first=Halie|title=After a 'long road,' the first phase of the Jacksonville Road project is open in Centre County|work=Centre Daily Times|date=November 11, 2022|url=https://www.centredaily.com/news/local/community/bellefonte/article268392837.html|access-date=November 15, 2022}}</ref> The local access interchange between PA&nbsp;26 and I-80 was funded in part by a $35-million federal grant, with a total estimated cost of $52&nbsp;million. The second phase of the project will make improvements to Jacksonville Road between the new interchange and the junction between I-80, and the third phase will build the high-speed interchange between I-80 and I-99. Bidding on the second and third phases was planned to begin in March 2022, with the improvements to Jacksonville Road to be finished by December 2023 and the high-speed interchange to be completed by December 2025.<ref name=gazette2019>{{cite news|title=PennDOT Details New Local Access Tied to I-80/I-99 Interchange Project|work=Centre County Gazette|date=March 1, 2019|url=http://www.statecollege.com/news/local-news/penndot-details-new-local-access-tied-to-i80i99-interchange-project,1479437/|access-date=March 2, 2019|archive-date=March 1, 2019|archive-url=https://web.archive.org/web/20190301190947/http://www.statecollege.com/news/local-news/penndot-details-new-local-access-tied-to-i80i99-interchange-project,1479437/|url-status=dead}}</ref> However, the bids for the other phases had not been released as of May 2023.<ref name="Phases" /> {{As of|June 2024}}, bidding began on the final phases.

During a 2002 taskforce meeting for I-99, it was suggested that [[Interstate 390|I-390]], which extends north from I-86 {{convert|24|mi|km}} west of the I-86/I-99 junction near Corning and which crosses I-90 and terminates in the greater [[Rochester metropolitan area, New York|Rochester metropolitan area]], be redesignated as I-99 once the I-80 to I-86 portion of that route is completed. The idea posits that I-390 is a logical extension of the I-99 corridor because I-99's predecessor, US&nbsp;15, originally extended to Rochester. No official moves to accomplish this have been taken.{{Cn|date=June 2023}}
