U.S. Route 22

U.S. Route 22 is an east–west United States Numbered Highway that runs from Cincinnati in Ohio to Newark in New Jersey. Established in 1926 as part of the original United States Numbered Highway System proposed by the American Association of State Highway Officials and influenced by planners associated with the Bureau of Public Roads, the route connects metropolitan regions including Cincinnati metropolitan area, the Lehigh Valley, and the New York metropolitan area. The highway passes through a mix of urban centers, industrial corridors, and Appalachian foothills, intersecting major routes such as Interstate 75, Interstate 71, Interstate 78, and U.S. Route 1.

Route description

The western terminus begins near downtown Cincinnati where the corridor interacts with Interstate 71 and U.S. Route 52 before heading east across Hamilton County, Ohio, traversing suburbs like Hamilton, Ohio and Middletown, Ohio. Entering Warren County, Ohio and Fairfield County, Ohio the alignment parallels regional rail corridors operated historically by the Pennsylvania Railroad and modern lines owned by Norfolk Southern Railway and CSX Transportation. Crossing into Pennsylvania, the roadway transits the Allegheny Plateau and passes through towns such as Pittsburgh, Weirton–Steubenville metropolitan area outskirts, and the industrial cities of Harrisburg, where connections to Pennsylvania Turnpike and Interstate 83 occur. East of Harrisburg the route follows valleys used by older turnpikes and canals associated with the Susquehanna River watershed, passing near the Lehigh Valley with access to Allentown, Bethlehem, and Easton, Pennsylvania. From eastern Pennsylvania the highway crosses the Delaware River into New Jersey at a point close to crossings used by the Delaware River Joint Toll Bridge Commission and continues through Phillipsburg, New Jersey, Rahway, New Jersey, and into Newark. Throughout its length the highway alternates between two-lane rural sections, four-lane divided arterials, and multilane urban expressways maintained by state departments such as the Ohio Department of Transportation, the Pennsylvania Department of Transportation, and the New Jersey Department of Transportation.

History

The route was designated with the 1926 nationwide grid that also created U.S. Route 1, U.S. Route 30, and U.S. Route 40, reflecting early 20th-century priorities tied to organizations like the American Association of State Highway Officials and federal agencies including the Bureau of Public Roads. Early alignments followed 19th-century turnpikes and 18th-century roads linked to colonial trade routes and Revolutionary War movements near Valley Forge and Trenton, New Jersey. Mid-20th-century changes paralleled the rise of the Interstate Highway System championed during the Dwight D. Eisenhower administration, which led to realignments where portions were replaced or paralleled by Interstate 78 and Interstate 76. Urban bypasses were constructed amid postwar suburbanization affecting regions like Cincinnati metropolitan area and the Lehigh Valley, influenced by planners and contractors from firms that worked on projects with agencies such as the Federal Highway Administration. Notable improvements include river crossings upgraded in coordination with the U.S. Army Corps of Engineers and reconstruction projects associated with economic shifts tied to deindustrialization in regions formerly served by the Bethlehem Steel Corporation and revitalization efforts seen in downtowns revitalized alongside initiatives by municipal governments and regional planning commissions.

Major intersections

The corridor intersects numerous Interstate and U.S. routes, including major junctions with Interstate 75 and Interstate 71 near Cincinnati, connections with U.S. Route 40 and U.S. Route 30 in Ohio and Pennsylvania, an interchange with Interstate 76 near Harrisburg, and an extensive concurrency and crossing with Interstate 78 in eastern Pennsylvania and New Jersey. Other significant intersections include U.S. Route 1 and U.S. Route 9 approaches to Newark, links to Interstate 95/New Jersey Turnpike infrastructure, and numerous state routes such as Pennsylvania Route 33 and New Jersey Route 24. Rail and port interfaces occur near Pittsburgh freight yards, the Port of Newark, and regional airports including Pittsburgh International Airport and Newark Liberty International Airport that influence traffic patterns on the highway.

Special routes

Several auxiliary alignments and business routes were established to serve downtowns bypassed by mainline realignments. Examples include business loops serving Cincinnati, Allentown, and Newark area central business districts, as well as truck bypasses around congested corridors maintained by state agencies like the Ohio Department of Transportation. Historic alignments paralleling the main route are preserved in local road names tied to old turnpikes and canals—sites of historical interest include locations near Valley Forge National Historical Park and heritage corridors connected to the Erie Canal era—while coordinated signage for alternate paths often references county route systems and municipal wayfinding programs.

Future and planned developments

Planned work along the corridor involves capacity upgrades, interchange reconstructions, and safety improvements driven by state plans from the Ohio Department of Transportation, Pennsylvania Department of Transportation, and New Jersey Department of Transportation. Projects under study include bridge replacements coordinated with the U.S. Army Corps of Engineers, corridor enhancements to improve freight access tied to facilities serving the Port of New York and New Jersey, and multimodal integration near transit hubs such as Newark Penn Station and Allentown's Lehigh Valley International Airport. Funding and scheduling are influenced by federal aid programs administered by the Federal Highway Administration and regional Metropolitan Planning Organizations including the Lehigh Valley Planning Commission and the North Jersey Transportation Planning Authority; proposals range from incremental resurfacing contracts with engineering firms to larger bypass or widening efforts subject to environmental review under statutes administered at state and federal levels.
