New Jersey State Highway Routes
Route 20, known locally as McLean Boulevard, is a state highway that runs 4.15 miles (6.68 km) in New Jersey, United States. It runs along the east side of Paterson, Passaic County, following the west bank of the Passaic River between U.S. Route 46 and River Street (County Route 504), at which point County Route 504 begins. It is a four- to six-lane divided highway most of its length that runs through residential and commercial areas of Paterson, intersecting with Interstate 80 and Route 4 at interchanges. The northernmost part of the route is a county-maintained one-way pair that follows 1st and 2nd Avenues.
The current alignment of Route 20 was legislated in 1927 as part of Route 3 north of Market Street and part of Route 4 south of that route's current western terminus at Route 20. McLean Boulevard was built in 1931. In 1953, Route 20 was designated to follow the Route 3 alignment between Paterson and East Rutherford as that route was moved to the Route S3 freeway between East Rutherford and Clifton. A freeway called the Paterson Peripheral was planned for Route 20 in 1959 between the Garden State Parkway in Clifton and downtown Paterson; the portion between the Garden State Parkway and Interstate 80 was complete by 1971 and it received the Route 20 designation at that time.
In East Rutherford, Route 20 was designated in 1972 along the Paterson Plank Road between Route 3 and Route 17. As a result of three separate segments of Route 20 existing that wound not be connected, they received three different designations by the 1990s. The freeway between the Garden State Parkway and Interstate 80 became Route 19, the portion between Route 3 and Route 17 in East Rutherford became Route 120, and the route along McLean Boulevard kept the Route 20 designation.
Route 20 begins at an interchange with U.S. Route 46 and County Route 630 (Crooks Avenue) just north of the Garden State Parkway on the border of Clifton and Paterson the Passaic River, heading to the north into Paterson as McLean Boulevard, a four-lane divided highway with a 45 mph (72 km/h) speed limit. The route runs in between the Passaic River to the east and two large cemeteries to the west before coming to an interchange with Interstate 80 and Market Street. Past Interstate 80, Route 20 becomes a six-lane divided highway that heads through a mix of residential and commercial areas.
