Route 46 and Notch Road Interchange

Little Falls and Woodland Park

Route 3 and Valley Road Interchange

Clifton


Overview

The New Jersey Department of Transportation (NJDOT) is in Final Design of the proposed operational and safety improvements for two Passaic County interchanges - Route 46 and Notch and Rifle Camp Roads in Little Falls and Woodland Park and Route 3/Valley Road in Clifton. These two interchanges have become chronic bottlenecks due to heavy traffic volumes during peak hours.

Estimated project schedule


Begin Final Design April 2009
Community outreach Fall 2010
Complete Final Design Summer 2011
Start construction To be determined

In this Final Design stage, these will be completed in 2010/2011:
  • right of way requirements
  • access changes
  • environmental permits
  • final design

History

The NJDOT’s Bureau of Project Scope Development completed a Feasibility Assessment Study in 2001 to determine the transportation problems and needs along Route 46 from the interchange with Notch and Rifle Camp Roads in Little Falls and Woodland Park to the Route 3/Valley Road interchange in Clifton, Passaic County. The study resulted in the selection of an Initially Preferred Alternative (IPA) for operational and safety improvements at Route 46 and Route 3 to conform to current design standards.

Following completion of scope development, NJDOT re-evaluated improvements to reduce project-related impacts and cost without sacrificing the intended outcome of the original project. The current plan, referred to as the Proposed Improvements Plan, reduces impacts to major utility infrastructure and to the environment.

Project area

The project area extends along Route 46 from the vicinity of Lower Notch Road to Rock Hill Road and along Route 3 from Valley Road to west of Grove Street, in Little Falls, Woodland Park and Clifton, Passaic County.

Proposed interchange improvements

The proposed improvements at the Notch Road/Rifle Camp Road interchange include the re-striping of the existing intersection on the south side of Route 46 and a new roundabout on the north side of Route 46 to improve traffic flow and sight distance. At Clove Road, a new interchange will improve access to Route 46 westbound. Improvements to the Route 46/Route 3/Valley Road interchange include reconstruction and reconfiguration of the ramps, a new traffic signal on Valley Road and a new roundabout at the intersection of the Valley Road, Great Notch Road and the new Route 3 exit ramp.

Proposed structural improvements

The proposed project will require five new bridge structures and one superstructure replacement, each designed to improve physical condition and substandard vertical under clearance. The Notch Road/Rifle Camp Road superstructure will be replaced. The structure will be widened to provide two turning lanes, shoulders and sidewalks.

  • A new bridge structure will be constructed over Route 46 at Clove Road as part of the Clove Road interchange improvement.
  • The Route 46 over Valley Road bridge will be replaced under staged construction to provide auxiliary lanes at the Route 46 and Route 3 connection.
  • Three replacement bridges at the Route 46 and Route 3 interchange will provide for the reconfiguration of ramps to meet current standards.
In addition, a number of retaining walls will be constructed at various locations due to grade differentials. They will vary in height from a minimum of 3’ to approximately a maximum of 30’.

Proposed roadway improvements

From Notch/Rifle Camp Road to the Valley Road interchange, Route 46 will be widened to provide shoulders and acceleration/deceleration lanes, to reduce mainline weaving caused by the closely spaced driveways and access points on Route 46 and at the Route 46/Route 3 diverge. Three lanes are proposed to replace the existing two lane connections at the intersection of Route 46 and Route 3 eastbound. Route 46 will be realigned to converge with Route 3 from the right (not from the left as currently exists) Additional roadway improvements include:

  • construction of a new two-way service road (Great Notch Road) on the north side of Route 46 connecting Notch Road to Valley Road to remove traffic and reduce weaving on Route 46 westbound
  • widening of Route 46 westbound to provide an auxiliary lane between Rock Hill Road and Valley Road
  • the realignment of the Route 46 eastbound exit and entrance ramps and the construction of a modern roundabout at Clove Road
  • design of architectural screening to mitigate the proximity of residences to the highways

Expected traffic impacts

Improvements to Route 46 and Route 3 will improve the level of service. During construction, traffic will be maintained to provide uninterrupted service for the main roadways during peak hours.

Environmental considerations

  • Air and noise studies will concentrate on sensitive receptors where noise levels need to be addressed.
  • Feasibility studies and public meetings have resulted in consideration of architectural enhancement screens.
  • The Third River, which meanders across Route 46 via a series of culverts, will be realigned, only as needed, to accommodate the new and widened roadways. Improvements will focus on providing a watercourse that yields both flood and environmental benefits.
  • A comprehensive public involvement program will provide the opportunity for input from the three affected communities located along this section of roadway.

Geotechnical and utility considerations

During Final Design all underground and aerial utilities that are impacted by the project will be identified and relocated as needed. Both geotechnical and pavement assessments will be performed and subsurface information will be gathered. A Geotechnical Rock Engineering Report will provide rock cut slope recommendations for the widened Route 46 corridor.

Construction costs

The estimated construction cost of this project is over $150 million. Federal and state funds are being used for this project.
