'''Route 21''' is a [[state highway]] in [[North Jersey|Northern New Jersey]], running {{convert|14.35|mi|km|2|abbr=on}} from the [[Newark Airport Interchange]] with [[U.S. Route 1/9|US&nbsp;1-9]] and [[U.S. Route 22 in New Jersey|US&nbsp;22]] in [[Newark, New Jersey|Newark]], [[Essex County, New Jersey|Essex County]] to an interchange with [[U.S. Route 46|US&nbsp;46]] in [[Clifton, New Jersey|Clifton]], [[Passaic County, New Jersey|Passaic County]]. The route is a four- to six-lane [[Dual carriageway|divided highway]] known as '''McCarter Highway''' on its southern portion in Newark that serves as a connector between the Newark and [[Paterson, New Jersey|Paterson]] areas, following the west bank of the [[Passaic River]] for much of its length. It also serves as the main north&ndash;south highway through the central part of Newark, connecting attractions in [[Downtown Newark]] with [[Newark Liberty International Airport|Newark Airport]]. The portion of Route 21 through Newark is a surface arterial that runs alongside the elevated [[Northeast Corridor]] rail line through the southern part of the city and continues north through Downtown Newark while the portion north of Downtown Newark is a [[Controlled-access highway|freeway]]. Route 21 intersects many major roads including [[Interstate 78 in New Jersey|I-78]], [[New Jersey Route 27|Route 27]], and [[Interstate 280 (New Jersey)|I-280]] in Newark, [[New Jersey Route 7|Route 7]] in [[Belleville, New Jersey|Belleville]], and [[New Jersey Route 3|Route 3]] in [[Clifton, New Jersey|Clifton]].

Route 21 was created in 1927 to run from Newark to Belleville. In 1948, the route was extended north to Paterson. In the 1950s construction began on the freeway portion of Route 21 and it was completed in stages between Chester Avenue in Newark and Monroe Street in [[Passaic, New Jersey|Passaic]] between 1958 and 1973. Plans were made to extend the freeway north to [[Interstate 80 in New Jersey|I-80]] in [[Elmwood Park, New Jersey|Elmwood Park]]; however, they were opposed by residents living on the east side of the Passaic River. In the 1980s, another northern extension of the Route 21 freeway was proposed to US&nbsp;46 in Clifton; this section was built between 1997 and 2000. The surface portion of Route 21 through Newark underwent many improvements in the 1990s and 2000s.

This section features the southbound lanes passing directly over the northbound lanes. The downtown Newark skyline is visible in the distance on the left.|thumb|right]]
Route 21 and CR 508 head along the west bank of the [[Passaic River]], passing by the [[New Jersey Performing Arts Center]]. CR 508 splits from Route 21 by heading east on Bridge Street, crossing the Passaic River, and Route 21 continues north, passing by the former site of [[Bears & Eagles Riverfront Stadium]]. After passing under NJ Transit's [[Montclair-Boonton Line]]/[[Morris & Essex Lines]] and interchanging with [[Interstate 280 (New Jersey)|I-280]], the route intersects with Clay Street ([[County Route 506 (New Jersey)#Special routes|CR 506 Spur]]). Past the intersection with 3rd Avenue, Route 21 becomes a six-lane [[Controlled-access highway|freeway]] again. After about a quarter mile, the northbound side swings under the southbound side and the freeway becomes double-decker, passes by Mt. Pleasant Cemetery, and returns to single-decker configuration. It then interchanges with Chester Avenue and Riverside Avenue with a southbound exit and northbound entrance before passing over [[Norfolk Southern Railway]]'s Newark Industrial Track line. Route 21 comes to a northbound exit and southbound entrance for Grafton Avenue and Mill Street; this interchange actually connects with the original McCarter Highway, a street that retains this name and acts as a service road to Route 21 for a few blocks in this area, near several industries. Route 21 briefly becomes a double-decker freeway again past the latter interchange and passes under Norfolk Southern Railway's [[Boonton Line]], before crossing into [[Belleville, New Jersey|Belleville]] at the [[Second River (New Jersey)|Second River]] crossing.<ref name=SLD/><ref name=gm/> The freeway features a southbound exit for Mill Street and a northbound exit for Rutgers Street/Belleville Turnpike ([[New Jersey Route 7|Route 7]] and [[County Route 506 (New Jersey)|CR 506]]) as it passes by houses on the left side of the freeway. Route 21 features an interchange with Main Street that has a southbound exit and an entrance in both directions. It enters [[Nutley, New Jersey|Nutley]] where the freeway interchanges with County Route 646 (Park Avenue), continuing north through residential areas along the Passaic River.<ref name=SLD/><ref name=gm/>

North of this point, the freeway comes to a northbound exit and southbound entrance for southbound River Road ([[List of county routes in Passaic County, New Jersey#624-2|CR 624]]), passing through residential neighborhoods, and enters [[Passaic, New Jersey|Passaic]]. In Passaic, Route 21 interchanges with Brook Avenue ([[List of county routes in Passaic County, New Jersey#608|CR 608]]), Van Houten Avenue ([[List of county routes in Passaic County, New Jersey#614|CR 614]]), and River Drive (CR 624). The route features an interchange with River Drive (CR 624) and Main Avenue ([[List of county routes in Passaic County, New Jersey#601|CR 601]]) and meets State Street at a partial interchange with a northbound exit and southbound entrance. This interchange provides access to the [[Union Avenue Bridge (Passaic River)|Union Avenue Bridge]] over the Passaic. Route 21 heads farther to the west of the Passaic River, passing through industrial and residential areas of Passaic. The freeway briefly enters [[Wallington, New Jersey|Wallington]] and comes to an interchange that provides access to Market Street ([[List of county routes in Passaic County, New Jersey#619|CR 619]]), Dayton Avenue, and Monroe Street. Route 21 continues to the north and resumes along the west bank of the Passaic River, narrowing to four lanes and crossing back into Clifton. Upon entering Clifton, the route comes to an interchange with Ackerman Avenue. The freeway heads to the northwest, passing by a park and featuring a southbound exit and northbound entrance for Lexington Avenue before ending at an interchange with [[U.S. Route 46|US 46]].<ref name=SLD/><ref name=gm/>

==History==
[[File:NJ 21 bridge stamp.jpg|thumb|right|Bridge stamp for Route 21 along former alignment, which was known as Route 21A.]]Route 21 history starts in 1927 with the New Jersey highway renumbering plan.<ref name="nj1927" /><ref name="nj1939" /> At that time it was set up as a surface roadway running through Newark and Belleville, with at-grade interchanges with local streets. This surface road eventually extended to Paterson.<ref name="nj1948" />

From the late 1950s through the early 1970s, much of the highway north of Newark was rebuilt as a limited-interchange freeway., through most of its portion in the City of Passaic. The remaining portion through downtown Passaic and the Botany Village portion of Clifton was not constructed until the last four years of the 20th century.<ref name=":1" />

Further improvements to the remaining surface portion were made to the Newark portion, though most of it remains as city streets.<ref name="njdot91503" /><ref name=":2" />

=== Original surface road ===
Route 21 was first defined in the [[1927 New Jersey state highway renumbering]] to run from [[New Jersey Route 25|Route 25]] (now US 1/9) and [[New Jersey Route 29|Route 29]] (now US 22) in Newark north to Belleville.<ref name="nj1927">State of New Jersey, Laws of 1927, Chapter 319.</ref><ref name="Map">{{cite map|url=http://www.jimmyandsharonwilliams.com/njroads/1920s/images/1927_routes.gif|title=1927 New Jersey Road Map|publisher=State of New Jersey|access-date=2008-10-08|url-status=dead|archive-url=https://web.archive.org/web/20071031111034/http://www.jimmyandsharonwilliams.com/njroads/1920s/images/1927_routes.gif|archive-date=2007-10-31}}</ref> The surface portion of Route 21 in Newark, which follows the Northeast Corridor rail line, was commissioned in 1934 between Routes 25 and 29 and Market Street and the portion through downtown Newark was commissioned in 1936 between Market Street and Clay Street. '''Route 19''' was designated in 1939 from Paterson to Belleville.<ref name="nj1939">State of New Jersey, Laws of 1939, Chapter 200.</ref> In 1948, the Route 21 designation was extended north to [[Paterson, New Jersey|Paterson]], replacing Route 19 (which has since been reassigned elsewhere).<ref name="nj1948">State of New Jersey, Laws of 1948, Chapter 235.</ref>

By Joint Resolution No. 4, approved March 22, 1934, the [[New Jersey Legislature]] designated Route&nbsp;21 as the McCarter Highway, in memory of Newark financier and philanthropist Uzal Haggerty McCarter.<ref>State of New Jersey; ''Laws of 1934, Joint Resolution No. 4''</ref>

=== Freeway ===
Plans for a freeway along the Route 21 corridor between Newark and Paterson date back to the early 1930s and became official in 1951.<ref>{{cite book|title=Passaic County Master Plan|publisher=Passaic County, New Jersey|year=1951}}</ref> In 1958, the highway was extended northward as a freeway along the west bank of the Passaic River to an interchange with Park Avenue in Nutley. Route 21 was extended to the Passaic Park interchange in 1962,<ref>{{Cite web|url=https://timesmachine.nytimes.com/timesmachine/1962/06/30/80407180.pdf|title=CENTER OF PASSAIC WILL LOSE TRACKS; Erie-Lackawanna Rerouted to Permit Continuation of New Freeway|work=The New York Times }}</ref> Main Avenue in 1968, and Monroe Street in 1973. 1970s legislation stopped the further extension northward until environmental impact could be assessed, leaving a two-mile city street portion in place to connect to Routes 20, 46, and [[Interstate 80 in New Jersey|I-80]] in Paterson for over 25 years.<ref name=":0" />

With the completion of the freeway to Monroe Street, a portion of the former route was briefly known as '''Route 21A'''.<ref>{{cite news|last=Waggoner|first=Walter H.|title=Fiscal Plan To Revivify Newark Offered|work=The New York Times|date=July 15, 1973}}</ref>{{Failed verification|date=September 2019}}

According to the original freeway plans, the portion north of Monroe Street was to cross over the Passaic River and terminated in [[Elmwood Park, New Jersey|Elmwood Park]] at the interchange of I-80 and [[County Route 507 (New Jersey)|CR 507]]. This routing would have allowed the highway continue with six full lanes. However, the proposal was opposed by residents who lived on the east side of the Passaic River, and for a quarter-century, traffic headed for Paterson had to use local streets in Passaic.

In the 1980s, plans were resurrected for completing the Route 21 freeway along the west bank of the Passaic River to US 46 in Clifton, avoiding the earlier objections.<ref name=":0">{{Cite news|url=https://www.nytimes.com/1995/09/24/nyregion/road-and-rail-in-passaic-a-road-to-nowhere-may-be-getting-somewhere.html|title = ROAD AND RAIL; in Passaic, a Road to Nowhere May be Getting Somewhere|newspaper = The New York Times|date = 24 September 1995|last1 = Chen|first1 = David W.}}</ref> Official plans were made in 1996, and in late 1997, construction began on this portion of the freeway.<ref>{{cite book|title=Route 21 Freeway Extension Project: Administrative Action Final Environmental Impact Statement and Section 4(f) Statement|publisher=Federal Highway Administration and New Jersey Department of Transportation|year=1996}}</ref><ref>{{cite news|last=Fitzgerald|first=Thomas J. and Maia Davis|title=Route 21 Completion Near|work=The Bergen Record|date=June 22, 1997}}</ref> It opened on December 20, 2000 at a cost of $136 million.<ref name=":1">{{cite news|last=Page|first=Jeffrey|title=Missing Link Is Finished After 28 Years|work=The Bergen Record|date=December 21, 2000}}</ref> However, this new route was limited mostly to four lanes (three lanes at the very northern end), utilizing the right of way of the [[Dundee Canal]]. A wider highway would have encroached on private property or the Passaic River, entailing much greater costs.

=== Newark section improvements ===
Sections of Route 21 through Newark were improved in the 1990s and the 2000s. The four-lane viaduct over the Northeast Corridor, which was built in the 1920s, was replaced between 1997 and 2003 at a cost of $253 million.<ref name="njdot91503">{{cite web|url=http://www.state.nj.us/transportation/about/press/2003/091503.shtm|title=Lettiere, Lautenberg cut ribbon on final phase of Route 21 Viaduct Project |date=September 15, 2003|publisher=[[New Jersey Department of Transportation]]|access-date=2012-04-06}}</ref> A major reconstruction occurred at the interchange with I-280 at the [[William A.

On April 27, 2018, the portion of Route 21 between mileposts 3.90 and 5.83 was dedicated the "Roberto Clemente Memorial Highway" after the late baseball legend [[Roberto Clemente]], who wore number 21 for his entire career with the [[Pittsburgh Pirates]].<ref>{{cite news|author=Staff|title=A portion of Route 21 is now named in honor of Roberto Clemente|work=TAPinto Newark|date=April 27, 2018|url=https://www.tapinto.net/towns/newark/articles/a-portion-of-route-21-is-now-named-in-honor-of-ro|access-date=June 1, 2018}}</ref>
