History

Route 21 history starts in 1927 with the New Jersey highway renumbering plan. 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. 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. Further improvements to the remaining surface portion were made to the Newark portion, though most of it remains as city streets.


Original surface road

Route 21 was first defined in the
1927 New Jersey state highway renumbering In 1927, New Jersey's state highways were renumbered. The old system, which had been defined in sequence by the legislature since 1916, was growing badly, as several routes shared the same number, and many unnumbered state highways had been d ...
to run from Route 25 (now U.S. Route 1/9) and Route 29 (now U.S. Route 22) in Newark north to Belleville.State of New Jersey, Laws of 1927, Chapter 319. 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.State of New Jersey, Laws of 1939, Chapter 200. In 1948, the Route 21 designation was extended north to Paterson, replacing Route 19 (which has since been reassigned elsewhere).State of New Jersey, Laws of 1948, Chapter 235. By Joint Resolution No. 4, approved March 22, 1934, the

designated Route 21 as the McCarter Highway, in memory of Newark financier and philanthropist Uzal Haggerty McCarter.


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. 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, 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

in Paterson for over 25 years. With the completion of the freeway to Monroe Street, a portion of the former route was briefly known as Route 21A. According to the original freeway plans, the portion north of Monroe Street was to cross over the Passaic River and terminated in Elmwood Park at the interchange of Interstate 80 and County Route 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 U.S. Route 46 in Clifton, avoiding the earlier objections. Official plans were made in 1996, and in late 1997, construction began on this portion of the freeway. It opened on December 20, 2000 at a cost of $136 million. 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 gretaer 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. A major reconstruction occurred at the intersection with Interstate 280 at the
