Interstate Highway in Pennsylvania, New Jersey, and New York

Interstate 78 (I 78) is an east–west Interstate Highway in the Northeastern United States that runs 144 mile (232 km) from I 81 northeast of Harrisburg, Pennsylvania through 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 percent of all truck traffic in the nation. 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.

After the I 78 Toll Bridge, I 78 enters New Jersey as the Phillipsburg–Newark Expressway. The road begins by running parallel with County Route 642 (CR 642) in the town of Alpha. At 3.94 mile (6 km), a partial cloverleaf interchange brings together US 22, Route 122, and Route 173 with I 78 in Phillipsburg. US 22 now runs concurrently with I 78 for the next 15 mile (24 km). Going westbound, exit 4 leaves to the right for CR 637 and Warren Glen. The next exit, exit 6, is for CR 632 in Bloomsbury. The route number is not signed on I 78. Exit 7 in Bloomsbury is the first of several eastbound exits for Route 173, which runs parallel the Interstate. 4 mile (6 km) later, exit 11 leaves to the right as another exit for Route 173. CR 614 is located off the exit. Exit 12 westbound is for Route 173 again. Exit 12 eastbound is for a frontage road paralleling I 78. Exit 13 is only westbound and is another exit for Route 173. Nearby the exit, going eastbound, the frontage road merges in.

All of I 78's auxiliary routes serve New York City; however, none of these routes actually intersect I 78, following the route's truncation at the eastern end of the Holland Tunnel. runs from US 1/9 in Linden, New Jersey, over the Goethals Bridge, through Staten Island, over the Verrazzano Narrows Bridge and through Brooklyn and Queens, and across the Triborough Bridge into the Bronx to end at I 95 at the Bruckner Interchange. and was to intersect I 78 at the east end of the Williamsburg Bridge in Brooklyn. though the project was later canceled. runs from I 278 at the Bruckner Interchange south over the Bronx–Whitestone Bridge to John F. Kennedy International Airport. is an unsigned designation for part of NY 878, a short west–east freeway on the north edge of John F. Kennedy International Airport. It was once planned as part of I 78 and now intersects I 678. The number was assigned in 1970. A former I 878 existed from 1959 to 1972 along present I 278 east of NY 895. (NY 895 was part of I 278.) In the Lehigh Valley region of eastern Pennsylvania, PA 378, which exits in downtown Bethlehem was once I 378 but was predesignated as a state route after I 78 was rerouted to a new southerly alignment. I 178 was initially planned to extend in Center City Allentown, but local opposition to the plan led to it being cancelled.
