U.S. Route 46

U.S. Route 46 is an east–west United States Numbered Highway running entirely within New Jersey, connecting the Delaware River at the Delaware Water Gap with the Newark Bay area near Newark. The route serves as a major arterial linking suburban and urban centers such as Sussex County, Morris County, Passaic County, Bergen County, and Hudson County while intersecting key corridors including Interstate 80, Interstate 287, Garden State Parkway, and New Jersey Turnpike.

Route description

U.S. Route 46 traverses landscapes from the Kittatinny Mountains and the Appalachian Mountains region near the Delaware Water Gap National Recreation Area through the Skylands Region into the densely developed New Jersey Meadowlands. Beginning at the Delaware River crossing adjacent to the Delaware Water Gap Toll Bridge area near Portland and Hardwick Township, the highway heads east through communities such as Hampton Township, Netcong, Dover, and Parsippany-Troy Hills. Along the way it intersects state and federal routes including New Jersey Route 94, U.S. Route 206, Interstate 80, and Garden State Parkway near Clifton and East Rutherford. The corridor passes by facilities and landmarks like Sterling Forest State Park, Essex County College, Meadowlands Sports Complex, and industrial zones adjacent to Newark Liberty International Airport and the Port of New York and New Jersey. Eastbound, the route terminates near the approaches to the Lincoln Highway and the New Jersey Turnpike at Kearny and Secaucus.

History

The alignment that became U.S. Route 46 has roots in 19th-century turnpikes and colonial-era roads used for commerce between New York City and interior New Jersey towns such as Morristown and Pine Brook. In the early 20th century the corridor was part of auto trails and state routes established by the New Jersey State Highway Department and later reorganized under the United States Numbered Highway System in 1926. During the 1930s and 1940s improvements tied the route to regional projects like the expansion of Interstate 80 and the development of the Garden State Parkway under figures such as Francis W. Lippincott (state highway officials) and planning agencies including the New Jersey State Highway Authority. Post-World War II suburbanization involving municipalities like Wayne, Lodi, and Hackensack increased traffic, prompting widening and interchange projects coordinated with agencies such as New Jersey Department of Transportation and regional planning bodies like the Port Authority of New York and New Jersey. Notable events affecting the route include capacity upgrades during the Interstate Highway System era and reconstruction tied to major transportation incidents and urban renewal in Hudson County and Bergen County.

Major intersections

Major junctions along the route include crossings and interchanges with prominent corridors and local arteries: - Western terminus at the Delaware River crossing near Delaware Water Gap Toll Bridge connecting to Pennsylvania approaches. - Intersection with New Jersey Route 94 in the northwest region near Sussex County communities. - Junction with U.S. Route 206 in the vicinity of Dover. - Interchange with Interstate 80 near Netcong/Mount Olive Township. - Concurrency and interface with New Jersey Route 10 and Interstate 287 in Parsippany and Whippany areas. - Connection to Garden State Parkway and access to Meadowlands Sports Complex near East Rutherford. - Crossings with U.S. Route 1/9, New Jersey Route 3, and proximity to Newark Liberty International Airport near Kearny and Secaucus. - Eastern terminus approaches at the New Jersey Turnpike/Lincoln Highway corridor and access to Newark Bay port facilities.

Related routes

Several state and federal routes interact with the corridor, including spurs, business routes, and formerly designated alignments associated with regional networks: - U.S. Route 206 and its historical alignments through Morris County. - New Jersey Route 3 connecting to Secaucus Junction and Jersey City. - New Jersey Route 10 providing east–west access toward East Hanover and Parsippany. - Interstate 80 and Interstate 287 as major interstate connectors serving Paterson and Wayne. - Local county routes including CR 511 and CR 513 that parallel or feed into the corridor. - Historical connections to auto trails and earlier state designations that influenced subsequent numbering under the American Association of State Highway Officials and state highway reorganizations.

Future and improvements

Planned and proposed improvements have been advanced by agencies such as the New Jersey Department of Transportation, regional planning entities like the North Jersey Transportation Planning Authority, and federal partners including the Federal Highway Administration. Projects include interchange reconstructions near Parsippany, capacity increases around Dover and Netcong, and modernization of bridges spanning waterways like the Passaic River and access improvements to hubs such as Newark Liberty International Airport and the Port Newark-Elizabeth complex. Funding and timelines are influenced by initiatives under Fixing America's Surface Transportation Act and state capital programs overseen by officials from entities such as the Governor of New Jersey's office and the New Jersey Economic Development Authority.
