'''Interstate&nbsp;78''' ('''I-78''') is an east–west [[Interstate Highway]] in the [[Northeastern United States]] that runs {{Convert|144|mi|km}} from [[Interstate 81|I-81]] northeast of [[Harrisburg, Pennsylvania]], through [[Allentown, Pennsylvania|Allentown]] to western and [[North Jersey]], terminating at the [[Holland Tunnel]] entrance to [[Lower Manhattan]] in [[New York City]]. Major metropolitan areas along I-78 include the [[Lehigh Valley]] in [[Pennsylvania]], the [[Gateway Region]] in New Jersey, and the [[New York metropolitan area]].

I-78 links ports in New York City and [[North Jersey]] to points west, including the Lehigh Valley, the third-largest metropolitan region of [[Pennsylvania]]. I-78 accommodates over four million trucks annually, representing 24&nbsp;percent of all truck traffic in the nation.<ref>{{Cite web |title=New Jersey's Infrastructure for Business {{!}} Choose New Jersey |url=https://www.choosenj.com/new-jerseys-assets/infrastructure/ |access-date=2022-05-29 |website=Choose New Jersey, Inc. |language=en-US}}</ref> It also is a major connection point to the New York metropolitan area's three major international airports, [[Newark Liberty International Airport]], [[John F. Kennedy International Airport]], and [[LaGuardia Airport]].

I-78 begins at a [[directional T interchange]] with [[Interstate 81|I-81]] in [[Union Township, Lebanon County, Pennsylvania|Union Township]], about {{convert|25|mi|km}} northeast of [[Harrisburg, Pennsylvania|Harrisburg]]. Near the east end of the county, at exit&nbsp;8, [[U.S. Route&nbsp;22]] (US&nbsp;22) merges with I-78, and runs concurrently for the next {{convert|43|mi|km}} through [[Berks County, Pennsylvania|Berks]] and [[Lehigh County, Pennsylvania|Lehigh]] counties.<ref>{{google maps |url = https://maps.google.com/maps?f=q&hl=en&geocode=&q=Bethel,+PA&ie=UTF8&ll=40.450605,-76.065216&spn=1.92281,3.641968&z=8&om=1 |title = Overview Map of I-78 in Lebanon, Berks, and Lehigh Counties |access-date = August 31, 2007 }}</ref>

At exit&nbsp;51, in [[Upper Macungie Township, Pennsylvania|Upper Macungie Township]], US&nbsp;22 leaves the highway. Drivers on I-78 eastbound must use this exit to access [[Interstate 476|I-476]], also known as the Northeast Extension of the [[Pennsylvania Turnpike]], and westbound travelers must use exit&nbsp;53 (northbound [[Pennsylvania Route&nbsp;309]], PA&nbsp;309) and then westbound US&nbsp;22. From exits&nbsp;53 to 60, I-78 runs concurrently with PA&nbsp;309. The six-lane overlap bypasses the city of [[Allentown, Pennsylvania|Allentown]] to the south and crosses [[South Mountain (Eastern Pennsylvania)|South Mountain]].<ref>{{google maps |url = https://maps.google.com/maps?f=q&hl=en&geocode=&q=I-78,+Allentown,+PA&sll=40.486649,-76.065216&sspn=0.015014,0.028453&ie=UTF8&ll=40.570464,-75.538559&spn=0.239926,0.455246&z=11&om=1 |title = Overview Map of I-78 Southeast of Allentown |access-date = August 31, 2007 |link = no }}</ref><ref>{{google maps |url = https://maps.google.com/maps?f=q&hl=en&geocode=&q=I-78,+Allentown,+PA&sll=40.486649,-76.065216&sspn=0.015014,0.028453&ie=UTF8&ll=40.564294,-75.483027&spn=0.001875,0.003557&t=k&z=18&om=1 |title = Overview Satellite Image of I-78 with Six Lanes |access-date = August 31, 2007 |link = no }}</ref>

At exit&nbsp;71, [[Pennsylvania Route 33|PA&nbsp;33]] reaches its southern terminus at a [[trumpet interchange]]. PA&nbsp;33 traverses the [[Pocono Mountains]] as it enters [[Bangor, Pennsylvania|Bangor]] and crosses [[Interstate 80|I-80]]. The final exit on I-78 in Pennsylvania is Morgan Hill Road, which accesses [[Pennsylvania Route 611|PA&nbsp;611]] and [[Easton, Pennsylvania|Easton]]. I-78 then crosses the [[I-78 Toll Bridge]] and enters [[New Jersey]].

Going westbound, exit&nbsp;4 leaves to the right for [[County Route 637 (Warren County, New Jersey)|CR&nbsp;637]] and [[Warren Glen, New Jersey|Warren Glen]]. The next exit, exit&nbsp;6, is for [[County Route 632 (Warren County, New Jersey)|CR&nbsp;632]] in [[Bloomsbury, New Jersey|Bloomsbury]]. The route number is not signed on I-78. Exit&nbsp;7 in Bloomsbury is the first of several eastbound exits for Route&nbsp;173, which runs parallel the Interstate. {{convert|4|mi|km|spell=In}} later, exit&nbsp;11 leaves to the right as another exit for Route&nbsp;173. [[County Route 614 (Warren County, New Jersey)|CR&nbsp;614]] is located off the exit. Exit&nbsp;12 westbound is for Route&nbsp;173 again. Exit&nbsp;12 eastbound is for a [[frontage road]] paralleling I-78.

Exit&nbsp;13 is only westbound and is another exit for Route&nbsp;173. Nearby the exit, going eastbound, the frontage road merges in.<ref name="googlenj"/> Exit&nbsp;15 is for Route&nbsp;173 and [[County Route 513 (New Jersey)|CR&nbsp;513]] in [[Franklin Township, Hunterdon County, New Jersey|Franklin Township]]. Exit&nbsp;17 is for [[New Jersey Route 31|Route&nbsp;31]] in [[Clinton Township, New Jersey|Clinton Township]]. In [[Annandale, New Jersey|Annandale]], US&nbsp;22 leaves I-78 at exit&nbsp;18. US&nbsp;22 continues to [[Bound Brook, New Jersey|Bound Brook]] and [[Union County, New Jersey|Union County]]. At exit&nbsp;20, [[County Route 639 (Hunterdon County, New Jersey)|CR&nbsp;639]] intersects. CR&nbsp;639 heads to the [[Round Valley Reservoir]]. Exit&nbsp;24 is for [[County Route 523 (New Jersey)|CR&nbsp;523]] to [[Oldwick, New Jersey|Oldwick]]. At exit&nbsp;29, [[Interstate 287|I-287]], [[U.S. Route 202|US&nbsp;202]], and [[U.S. Route 206|US&nbsp;206]] interchange with I-78 in [[Bedminster, New Jersey|Bedminster]]. At this point, in [[Somerset County, New Jersey|Somerset County]], exits&nbsp;33, 36, and 40 are for county routes in [[Warren Township, New Jersey|Warren Township]]. At exit&nbsp;41, I-78 enters Union County<ref name="googlenj"/> and then passes through the [[Watchung Reservation]], where land bridges cross over the highway to allow for the safe passage of wildlife. At exit&nbsp;45, [[County Route 527 (New Jersey)|CR&nbsp;527]] intersects after paralleling for some time. West of exit&nbsp;48, I-78 splits into express and local highways. Exit&nbsp;48 is for [[New Jersey Route 24|Route&nbsp;24]] in [[Springfield Township, Union County, New Jersey|Springfield Township]]. Exit&nbsp;49A is for one of Route&nbsp;24's spur routes, [[New Jersey Route 124|Route&nbsp;124]]. Exit&nbsp;52 is for the [[Garden State Parkway]] in [[Union Township, Union County, New Jersey|Union Township]]. At exits&nbsp;57 and 58, [[New Jersey Route 21|Route&nbsp;21]], [[U.S. Route 1|US&nbsp;1]], [[U.S. Route 9|US&nbsp;9]], and US&nbsp;22 intersect I-78. The exit provides access to [[Newark Liberty International Airport]].

East of exit&nbsp;58 at the eastern tip of [[Newark, New Jersey|Newark]], I-78 becomes the Newark Bay Extension of the [[New Jersey Turnpike]]. Past the first toll plaza, I-78 has an interchange with [[Interstate 95|I-95]] (New Jersey Turnpike) and crosses [[Newark Bay]] via the [[Newark Bay Bridge]].<ref name="googlenj"/> The first exit, 14A, is for [[New Jersey Route 440|Route&nbsp;440]] in [[Bayonne, New Jersey|Bayonne]]. [[Liberty State Park]] can be reached by taking exit&nbsp;14B. Exit&nbsp;14C is the final numbered exit, providing access to the [[Liberty Science Center]]. [[New Jersey Route 139|Route&nbsp;139]] runs concurrently with I-78 along a [[one-way pair]] of surface streets as it approaches the [[Holland Tunnel]] and enters [[New York (state)|New York]] state.

===New York===
{{main|Interstate 78 in New York}}
{{see also|Holland Tunnel}}
[[File:Holland tunnel.jpg|thumb|I-78 leaving [[Jersey City, New Jersey|Jersey City]] and entering the [[Holland Tunnel]] to [[SoHo, Manhattan|SoHo]] and [[New York City]]]]
I-78's length in [[New York (state)|New York]] is {{convert|0.5|mi|km}}—half of the Holland Tunnel and the egress-only [[roundabout]] immediately beyond the end of the tunnel. The route was planned to run east and north through New York City to end at [[Interstate 95|I-95]] in [[the Bronx]], but sections of the planned route, including the [[Lower Manhattan Expressway]], were canceled.

In New York City, I-78 continues through the egress-only roundabout known as the Saint John's Rotary. The five separate exits from the Rotary are assigned numbers, exits&nbsp;1 to 5, in counterclockwise order. Exit&nbsp;5, the last eastbound exit, leads onto [[Canal Street (Manhattan)|Canal Street]]. Under original plans, I-78 was to cross [[Manhattan]] as the Lower Manhattan Expressway onto the [[Williamsburg Bridge]] and then beyond [[Interstate 278|I-278]] on [[Bushwick Expressway]] through [[Brooklyn]] into [[Queens]] near the [[John F. Kennedy International Airport]]. A section of I-78 at the airport was built as the [[Nassau Expressway]], later [[Interstate 878|I-878]] and now [[New York State Route 878]] (NY&nbsp;878), though most of the westbound side was never built. Under the plans, east of the airport, I-78 would have turned north on the [[Clearview Expressway]], built north of Hillside Avenue in Queens and now [[Interstate 295 (New York)|I-295]], run across the [[Throgs Neck Bridge]], and forked into two spurs, ending at I-95 via the [[Throgs Neck Expressway]], which is now [[Interstate 695 (New York)|I-695]] and the [[Bruckner Interchange]] via the [[Cross Bronx Expressway]], which is now part of I-295.<ref>{{Cite web |url=http://www.dot.state.ny.us/tech_serv/high/tvwebpag.html |title=NYSDOT - Traffic Count Information |access-date=December 27, 2005 |archive-url=https://web.archive.org/web/20060428101322/http://www.dot.state.ny.us/tech_serv/high/tvwebpag.html |archive-date=April 28, 2006 |url-status=dead }}</ref>

In the [[Lehigh Valley]] region of eastern Pennsylvania, [[Pennsylvania Route 378|PA&nbsp;378]], which exits in downtown [[Bethlehem, Pennsylvania|Bethlehem]], was once I-378 but was predesignated as a state route after I-78 was rerouted to a new southerly alignment. [[Interstate 178|I-178]] was initially planned to extend in [[Center City Allentown]], but local opposition to the plan led to it being cancelled.
