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.
