Route 46 and Notch Road Interchange

Little Falls and Woodland Park

Route 3 and Valley Road Interchange



Bridge Profile

The roadway vertical profile where the roadway crosses a bridge. Survey is used to assure that beam bearings are set to the proper elevation, so that beams and decks provide the proper riding surface elevations when constructed.

Collector-Distributor (CD) Roads

One directional roads adjacent to but separate from the main highway to facilitiate the safe transitioning of traffic from the highway to the local roadway network and vice versa.

Constructibility Review

An evaluation of proposed construction documents to verify that the project can be built safely as shown, traffic can be maintained during construction, and the purpose and needs of the project are met.

Contract Documents

Plans and specifications which direct the contractor as to how to construct the project.

Feasibility Assessment Study

A study to develop alternative designs to address the project needs and to assess the practicality of the various alternatives.

Final Scope Development

The refinement of the Initial Preferred Alternative (IPA) based upon environmental studies, community input and the needs of the traveling public.


The application of geology to engineering; in this case the support of structures and roadways.

Initially Preferred Alternative - (IPA)

The proposed roadway configuration identified during the Feasibility Assessment Review as being best suited for study during the Final Scope Development Stage.

Low Level Photography

Aerial photography taken at a relatively low altitude to obtain detailed mapping information.

North Jersey Transportation Planning Authority (NJTPA)

NJTPA is the agency coordinating transportation needs for the Northern New Jersey region.

Office of Community and Constituent Relations (CCR)

The New Jersey Department of Transportation's (NJDOT) Office of Community and Constituent Relations acts as liaison to local officials and citizens to learn and address their concerns.

Partnering Meetings

Partnering is a project management system designed to lower costs and improve communication. From the initial partnering session to project closeout, meetings focus on the project itself and related issues at hand. The intent is to ensure that the business processes work as smoothly as possible, with the focus on the project itself. Participants typically include NJDOT, NJDEP, governmental agencies, local public officials, utility companies, mass transit agencies, and Chambers of Commerce.

Project-specific web site

A web site devoted to a specific NJDOT project. This is the project-specific web site for the Route 46/Route 3/Valley Road/Notch Road Interchange Improvements Project.

Right of Way

The land required to construct the project, including and necessary walls and structures to support the roadway, and to provide access to adjacent properties if necessary.

Scoping Process

The Final Scope Development Stage where the IPA is refined and environmental issues are investigated to determine if the approach is viable.

Technical Environmental Studies

Detailed Quantitative analyses of the effect of the project on air and noise quality, architectural and archaeological features, wetlands, parkland, and adjacent property owners.

Topographical Mapping

Precise, detailed mapping of the ground surface and its features with regard to vertical and horizontal location.

Vertical Profile

The mathematical line representing the elevation of the riding surface of a roadway. This line is part of the Contract Documents and is established in the field by survey through an initial layout. Survey control during construction is provided to assure that the final conditions are in accordance with plans.
