Interstate 84 (I-84) inPennsylvania is the westernmost segment of the eastern I-84. Within Pennsylvania, it runs fromI-81 inDunmore east to theNew York border nearMatamoras.

I-84 starts in Pennsylvania atI-81 inDunmore, a suburb east ofScranton, along with the northern end ofI-380. After two miles (3.2 km), I-84 splits from I-380, as the latter goes southeasterly throughthe Poconos and I-84 continues almost due east intoWayne andPike counties.[citation needed]
This section of Pennsylvania is very lightly populated, and there are no major settlements on or near I-84, although it offers access to popular outdoor recreation areas such asLake Wallenpaupack andPromised Land State Park. Itsright-of-way is very wide, with a largemedian strip between the two carriageways as it passes through densely wooded country, except for the swampy areas in southern Wayne County. The only development along Pennsylvania's section of I-84 is whereU.S. Route 6 (US 6) andUS 209 start to parallel closely and form a commercial strip just south ofMatamoras, just west of theDelaware River.[citation needed] I-84 reaches its highest elevation in Pennsylvania and in the east just west of exit 8 at 1,800 feet (550 m).[2]
On October 15, 2011, the roadway was designated as theFallen Trooper Memorial Highway throughout its length.[3]

I-84 was originally planned torun concurrently withUS 6, but, in June 1958, due to a realignment ofI-80, I-84 was redesignated as an Interstate. The plan was first revealed to the public in 1964. The first segment to be completed and open to traffic was the bridge spanning the Delaware River between Pennsylvania and New York. The second section from exit 26 to exit 53 opened in 1972.[4]

I-84 was to continue west of I-380 and connect to I-81 atMoosic, but the alignment was moved further north, running concurrently with I-380 fromElmhurst Township to Dunmore. I-380 both ran east from I-81, sharing mileposts and exit numbers, with their split being an unnumbered exit 3 (in accordance withPennsylvania Department of Transportation (PennDOT) policy at the time which did not allow interchanges between Interstates to be numbered). During the 2001 exit renumbering, I-380 became a north–south Interstate and its mileposts and exit numbers were reversed. Locally, the four-mile (6.4 km) overlapping section is commonly spoken as "380, 84". When the exits were renumbered, the exit tabs with button-copy letters for the old exit 4 were moved to the new exit 4 in the eastbound direction and remained in place until the signs were updated.
