===Ohio===
[[Image:USHighway22.JPG|thumb|left|Old US&nbsp;22 marker located near the intersection of US&nbsp;22 and [[Ohio State Route 207|SR&nbsp;207]] in [[Pickaway County, Ohio]]]]
US&nbsp;22 has its westernmost endpoint in downtown [[Cincinnati]]. Its eastbound and westbound endpoints are not at the same intersection. Officially, US&nbsp;22 eastbound begins on Central Avenue ([[U.S. Route 27|US&nbsp;27]] northbound/[[U.S. Route 52|US&nbsp;52]] westbound/[[U.S. Route 127|US&nbsp;127]] northbound) at 5th Street, then proceeds north, turning east onto 7th Street. Meanwhile, US&nbsp;22 westbound follows 9th Street and officially ends at Central Avenue<ref>{{Cite web |title=U.S. Route 22 (Hamilton County) - Straight Line Diagram |url=https://www.dot.state.oh.us/TechnicalServices/SLD/SHAMUS00022.pdf |access-date=September 3, 2023 |publisher=[[Ohio Department of Transportation]]}}</ref> (signage designating the end occurs much sooner, approaching Elm Street, [[U.S. Route 42|US&nbsp;42]] northbound).<ref>{{Google maps|title=104 W 9th Street, Cincinnati, Ohio, United States|url=https://www.google.com/maps?f=q&source=s_q&hl=en&geocode&q=104+w+9th+cincinnati,+ohio&sll=41.950299,-86.418457&sspn=0.495351,1.400757&ie=UTF8&ll=39.105101,-84.515934&spn=0.002019,0.005472&z=18&iwloc=A&layer=c&cbll=39.105099,-84.515933&panoid=jCMFYtwQLCm_6u4cv-sE2w&cbp=12,279.52114318811556,,0,1.8235294117647042|access-date=September 3, 2023}}</ref>

From downtown Cincinnati to [[Washington Court House, Ohio|Washington Court House]], US&nbsp;22 roughly follows the historic 3-C Highway which connected Cincinnati, [[Columbus, Ohio|Columbus]], and [[Cleveland]]. This section is also concurrent with [[Ohio State Route 3|SR&nbsp;3]]. At Washington Court House, SR&nbsp;3 and US&nbsp;22 diverge. US&nbsp;22 continues to the east through [[Circleville, Ohio|Circleville]] to [[Lancaster, Ohio|Lancaster]]. From Lancaster to [[Zanesville, Ohio|Zanesville]], US&nbsp;22 roughly follows the route of [[Zane's Trace]], an early pioneer road blazed by [[Ebenezer Zane]] beginning in 1796.

Starting just west of [[Cadiz, Ohio|Cadiz]], US&nbsp;22 becomes a limited-access expressway for the remainder of its approximately {{Convert|30|mi|km}} in Ohio as it approaches and enters [[Greater Pittsburgh]] (with the exception of an at-grade intersection with no stoplights or signs on US&nbsp;22 and narrowing to two lanes for about {{One2a|{{convert|1|mi|km|spell=in}}}} east of Cadiz). It junctions with [[Ohio State Route 7|SR&nbsp;7]] for roughly {{One2a|{{convert|1|mi|km|spell=in}}}} along the [[Ohio River]] shoreline in [[Steubenville, Ohio|Steubenville]].

===West Virginia===

[[File:2017-07-23 14 01 02 View east along U.S. Route 22 (Robert C.

Known as the [[Robert C. Byrd]] Expressway, the expressway route that began roughly {{Convert|30|mi|km}} to the west near [[Cadiz, Ohio|Cadiz]], [[Ohio]], continues for approximately {{Convert|5|mi|km|spell=in}} within the state of [[West Virginia]] (the highway runs concurrent with [[West Virginia Route 2]], or WV&nbsp;2, for one of those miles, or {{Convert|1|mi|km|disp=output only}}) as it approaches more population density within Greater Pittsburgh. US&nbsp;22 travels through or borders the city of [[Weirton, West Virginia|Weirton]] for its entire length in West Virginia, from the Ohio state line over the [[Ohio River]], to the [[Pennsylvania]] state line.

===Pennsylvania===
{{Main|U.S. Route 22 in Pennsylvania}}
[[File:US 22 EB past Devonshire Road.jpeg|thumb|left|US&nbsp;22 eastbound in [[Colonial Park, Pennsylvania]], east of [[Harrisburg, Pennsylvania|Harrisburg]]]]
US&nbsp;22 enters [[Pennsylvania]] as a limited-access highway connecting [[Weirton, West Virginia]], and [[Steubenville, Ohio]], with [[Pittsburgh]]. Through much of [[Greater Pittsburgh]], it overlaps [[Interstate 376|I-376]] and [[U.S. Route 30|US&nbsp;30]]. US&nbsp;30 merges with US&nbsp;22 near [[Imperial, Pennsylvania|Imperial]] and [[Pittsburgh International Airport]], and both highways then merge with I-376 in [[Robinson Township, Allegheny County, Pennsylvania|Robinson Township]]. Together, these three highways form a busy, limited-access multiplex through the city of Pittsburgh. US&nbsp;30 then splits from I-376 and US&nbsp;22 in [[Wilkinsburg, Pennsylvania|Wilkinsburg]], and the I-376/US&nbsp;22 concurrency continues to the [[Pennsylvania Turnpike]] in [[Monroeville, Pennsylvania|Monroeville]], where I-376 ends.

East of I-376, US&nbsp;22 continues east of Pittsburgh as a primary arterial highway. The entire length between Pittsburgh and [[U.S. Route 220|US&nbsp;220]] and [[Interstate 99|I-99]] just west of [[Altoona, Pennsylvania|Altoona]] was widened to at least four lanes by mid-2011. I-99 links the highway to [[State College, Pennsylvania|State College]] and the Pennsylvania Turnpike. Heading east from I-99, US&nbsp;22 narrows and becomes the primary highway linking [[Hollidaysburg, Pennsylvania|Hollidaysburg]] and [[Huntingdon, Pennsylvania|Huntingdon]].  Near [[Mount Union, Pennsylvania|Mount Union]], it forms a concurrency with [[U.S. Route 522|US&nbsp;522]], and the two highways go northeast along the [[Juniata River]] to [[Lewistown, Pennsylvania|Lewistown]].

In Lewistown, US&nbsp;22 breaks with US&nbsp;522 and forms a concurrency with [[U.S. Route 322 in Pennsylvania|US&nbsp;322]], and the two routes travel southeast, mostly as an expressway, toward [[Harrisburg, Pennsylvania|Harrisburg]]. At the north end of Harrisburg, US&nbsp;22 and US&nbsp;322 split and US&nbsp;22 runs southward toward the [[Pennsylvania Farm Show Complex & Expo Center]]. From there, it turns eastward along Arsenal Boulevard, Herr Street, and Walnut Street to Jonestown Road. Through [[Dauphin County, Pennsylvania|Dauphin]] and [[Lebanon County, Pennsylvania|Lebanon]] counties, US&nbsp;22 parallels [[Interstate 81|I-81]] and [[Interstate 78|I-78]] to the south as a four-lane arterial. East of [[Fredericksburg, Lebanon County, Pennsylvania|Fredericksburg]], along the border between Lebanon and [[Berks County, Pennsylvania|Berks]] counties, US&nbsp;22 forms a concurrency with I-78, which runs to the [[Allentown, Pennsylvania|Allentown]] area. Former highway alignments of US&nbsp;22 that parallel this section are collectively known as the "Hex Highway", so called because of the Berks County-based [[Pennsylvania Dutch]] families that hang [[hex sign]]s on their barns.

In the [[Lehigh Valley]], US&nbsp;22 is a four-lane limited-access expressway between [[Easton, Pennsylvania|Easton]] and I-78 to the west; it is dually designated with the [[Lehigh Valley Thruway]] in Allentown. The original designation for this expressway was to be I-78, but local opposition to a freeway in [[Phillipsburg, New Jersey|Phillipsburg]], along with substandard conditions at Easton, forced federal highway officials to relocate I-78 south of Allentown, [[Bethlehem, Pennsylvania|Bethlehem]], Easton, and [[Phillipsburg, New Jersey|Phillipsburg]]. US&nbsp;22 then crosses the [[Delaware River]] on the [[Easton–Phillipsburg Toll Bridge]].

===New Jersey===
{{Main|U.S. Route 22 in New Jersey}}
[[File:2018-05-29 15 23 30 View east along U.S. Route 22 at Cramer Avenue in Green Brook Township, Somerset County, New Jersey.jpg|thumb|right|View east along US&nbsp;22 at Cramer Avenue in [[Green Brook, New Jersey]]]]
US&nbsp;22 in New Jersey predates and was largely replaced by [[Interstate 78|I-78]] after I-78 was built between 1956 and 1989<ref>{{cite web|url=http://www.nycroads.com/roads/I-78_NJ/|title=Interstate 78 (New Jersey)|publisher=nycroads.com}}</ref> and shares designation with I-78 from exit&nbsp;3 to exit&nbsp;18. US&nbsp;22 was an expressway in some segments, including the area around [[Perryville, New Jersey|Perryville]] and [[Clinton, New Jersey|Clinton]]. It connects [[Phillipsburg, New Jersey|Phillipsburg]] with [[Newark, New Jersey|Newark]] in New Jersey.

US&nbsp;22 has one major interchange besides I-78, that being [[Interstate 287|I-287]], although it is not a full interchange, with two missing movements: US&nbsp;22 eastbound to I-287 northbound and I-287 southbound to US&nbsp;22 westbound.

One of two [[level crossing]] of the highway happens in [[Union County, New Jersey|Union County]] in the [[Union Township, Union County, New Jersey|Union Township]] section of the highway (the other occurring in [[Lewistown, Pennsylvania]]). It once belonged to the [[Rahway Valley Railroad]]; the crossing was closed in 1992 when service on the railroad was ended.
