Union County, New Jersey in the context of "Central Jersey"

Newark Liberty International Airport (IATA: EWR, ICAO: KEWR, FAA LID: EWR) is a major international airport serving the New York metropolitan area. The airport straddles the boundary between the cities of Newark in Essex County and Elizabeth in Union County, in the U.S. state of New Jersey. Located approximately 4.5 miles (7.2 km) south of downtown Newark and 9 miles (14 km) west-southwest of Manhattan, it is a major gateway to destinations in Europe, South America, Asia, and Oceania. It is jointly owned by the two cities, and the airport itself is leased to its operator, the Port Authority of New York and New Jersey. It is the second-busiest airport in the New York airport system behind John F. Kennedy International Airport and ahead of LaGuardia Airport.

The airport is near the Newark Airport Interchange, the junction between both Interstate 95 and Interstate 78 (both of which are components of the New Jersey Turnpike), and U.S. Routes 1 and 9, which has junctions with U.S. Route 22, Route 81, and Route 21. AirTrain Newark connects the terminals with the Newark Liberty International Airport Railway Station. The station is served by NJ Transit's Northeast Corridor Line and North Jersey Coast Line. Amtrak's Northeast Regional and Keystone Service routes also make stops at the station.

The Arthur Kill (sometimes referred to as the Staten Island Sound) is a tidal strait in the New York–New Jersey Harbor Estuary between Staten Island (also known as Richmond County), New York, and Union and Middlesex counties, New Jersey. It is a major navigational channel of the Port of New York and New Jersey.

The Gateway Region is the primary urbanized area of the northeastern section of the U.S. state of New Jersey. The region is anchored by Newark, the state's most populous city, and constitutes part of the New York metropolitan area.

The area encompasses Bergen, Essex, Hudson, Passaic, Union, and Middlesex counties. It is the most urban part of the state, with a population of more than four million, and is home to most of its larger cities, though much housing was originally developed as suburbs of neighboring New York City. It is home to Ellis Island, the "gateway" through which many immigrants entered the United States, many of whom chose to stay in the region, which continues to be the port of entry and first home to many born abroad, making it one of the most ethnically diverse of the nation. It may also be the most socio-economically diverse, with some of the biggest pockets of poverty and most exclusive of suburbs in the state.

Elizabeth is a city in and the county seat of Union County, in the U.S. state of New Jersey. As of the 2020 United States census, the city is the most populous in the Central Jersey region and has retained its ranking as the state's fourth-most-populous city behind neighboring Newark, Jersey City and Paterson, with a population of 137,298, an increase of 12,329 (+9.9%) from the 2010 census count of 124,969, which in turn reflected an increase of 4,401 (3.7%) from the 120,568 counted in the 2000 census.

The Population Estimates Program calculated a population of 140,413 for 2024, making it the 201st-most populous city in the nation and the fifth-most populous municipality of any type in the state, falling behind Lakewood Township.

Interstate 278 (I-278) is an auxiliary Interstate Highway in New Jersey and New York in the United States. The road runs 35.62 miles (57.32 km) from US Route 1/9 (US 1/9) in Linden, New Jersey, northeast to the Bruckner Interchange in the New York City borough of the Bronx. The majority of I-278 is in New York City, where it serves as a partial beltway and passes through all five of the city's boroughs. I-278 follows several freeways, including the Union Freeway in Union County, New Jersey; the Staten Island Expressway (SIE) across Staten Island; the Gowanus Expressway in southern Brooklyn; the Brooklyn–Queens Expressway (BQE) across Northern Brooklyn and Queens; a small part of the Grand Central Parkway in Queens; and a part of the Bruckner Expressway in the Bronx. I-278 also crosses multiple bridges, including the Goethals, Verrazzano–Narrows, Kosciuszko, and Robert F. Kennedy bridges.

I-278 was opened in pieces from the 1930s through the 1960s. Some of its completed segments predated the Interstate Highway System and are thus not up to standards, and portions of I-278 have been upgraded over the years. In New York, the various parts of I-278 were planned by Robert Moses, an urban planner in New York City. The segments proposed tore through many New York City neighborhoods, causing controversy. Despite its number, I-278 does not connect to I-78. There were once plans to extend I-278 west to I-78 east of the Route 24 interchange in Springfield, New Jersey. This was canceled because of opposition from the communities along the route. The segment that does exist in New Jersey was opened in 1969. There were also plans to extend I-78 east across Manhattan and into Brooklyn via the Williamsburg Bridge; this would have been a second interchange between I-278 and its parent highway, but these plans were also thwarted. I-78 was also planned to extend east beyond I-278 to John F. Kennedy International Airport, and then curve northward on the Clearview Expressway, ending at the Bruckner Interchange in the Bronx. If these plans were fully completed, I-78 and I-278 would have met at three interchanges.

U.S. Route 22 (US 22) is a United States Numbered Highway stretching from Cincinnati, Ohio, in the west to Newark, New Jersey, in the east. In New Jersey, the route runs for 60.53 miles (97.41 km) from the Easton–Phillipsburg Toll Bridge over the Delaware River in Phillipsburg, Warren County, to Interstate 78 (I-78), US 1/9, and Route 21 at the Newark Airport Interchange in Newark, Essex County. The road first heads through the Phillipsburg–Alpha area as an arterial road before running concurrent with I-78 through mountainous and agricultural sections of western New Jersey between Alpha and east of Clinton in Hunterdon County. For the remainder of the route, US 22 runs to the south of I-78 through mostly suburban areas as a four- to six-lane arterial road, passing through Hunterdon, Somerset, Union, and Essex counties. Along this portion, it intersects US 202 and US 206 in Somerville, I-287 in Bridgewater Township, and the Garden State Parkway in Union.

What became US 22 in 1926 was first designated as Route 9, a route running from Phillipsburg to Elizabeth, in 1916. In 1927, Route 9 west of Elizabeth became Route 28 while the portion within Elizabeth became Route 27-28 Link. By 1941, US 22 was moved to its current alignment in the Phillipsburg area, following Route 24 and Route 24-28 Link; Route 28 in Phillipsburg became US 22 Alternate (US 22 Alt.; now Route 122). Also, US 22 was moved off Route 28 east of Bridgewater Township to follow Route 28-29 Link and Route 29 to Newark. In 1953, the long concurrencies with the state highways were removed. In the 1960s, I-78 was constructed close to the US 22 corridor throughout New Jersey. US 22 was moved onto the new Interstate between Alpha and Clinton in 1969 with most of the old route becoming Route 173.

Route 81 is a state highway in the U.S. state of New Jersey. The route is a freeway connector between exit 13A of the New Jersey Turnpike (Interstate 95 [I-95]) and U.S. Route 1/9 (US 1/9) near Newark Liberty International Airport. It runs for 1.18 miles (1.90 km), entirely within the city of Elizabeth in Union County. A freeway called Route S100 was initially proposed on the current alignment of Route 81 in 1938; it, along with its parent Route 100, was never built. The current route was conceived in the 1960s as a freeway replacement for Route 164, which followed Humboldt Avenue, a surface road. It was to be designated Route 76, but was renumbered to Route 81 when I-76 was created in New Jersey.

It was legislated in 1966 to run parallel to the New Jersey Turnpike from exit 13 until North Avenue, where it would turn northwest and intersect US 1/9 near the airport. The routing was eventually shifted to begin from a new interchange along the New Jersey Turnpike. A total of $50 million in funding was allocated for the road and the Port Authority of New York and New Jersey was responsible for designing the road. The state had wanted the port authority to pay for construction; however it was ruled that they could not build the road. Construction on Route 81 took place between 1979 and 1982.
