context_page_description: U.S. Route 22 is a U.S. highway stretching from Cincinnati, Ohio in the west to Newark, New Jersey in the east. In New Jersey, the route runs for 60.53 mi from the Easton–Phillipsburg Toll Bridge over the Delaware River in Phillipsburg, Warren County to Interstate 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 a surface divided highway 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 surface divided highway, 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 pre-1927 Route 9, a route running from Phillipsburg to Elizabeth, in 1916. In 1927, pre-1927 Route 9 west of Elizabeth became Route 28 while the portion within Elizabeth became Route 27-28 Link.
context_section_description: Upon splitting from I-78, US 22 becomes a four-lane at-grade divided highway that runs through rural areas with some development and crosses NJ Transit’s Raritan Valley Line. It enters Lebanon, passing to the north of the town center. Upon leaving Lebanon, the route heads back into Clinton Township. In the community of Potterstown, US 22 enters Readington Township and takes a southeasterly turn away from I-78. Here, the road passes to the southwest of the Merck Headquarters Building before reaching the community of Whitehouse Station, where it has a short concurrency with CR 523. Past Whitehouse Station, US 22 continues through a mix of residential and commercial areas.
  US 22 continues into Branchburg Township, Somerset County, where development near the road increases but remains mostly rural. CR 614 parallels US 22 to the north to pass through the community of North Branch before US 22 intersects CR 637 and crosses the North Branch Raritan River into Bridgewater Township. In Bridgewater Township, the route comes to an interchange with the eastern terminus of CR 614 and the western terminus of Route 28. Past this interchange, US 22 passes business parks and the Raritan Valley Country Club, widening to six lanes in the process. Afterwards, it comes to an interchange with US 202 and US 206. Past this interchange, US 22 quickly transitions from a rural to a more suburban setting and heads east along the border of Somerville to the south and Bridgewater Township to the north, passing near the Bridgewater Commons shopping mall. The median of the route widens as it runs immediately to the south of I-287, fully entering Bridgewater Township again as it comes to an interchange with I-287 at exits 14A and 14B.
