Route 46 and Notch Road Interchange
Little Falls and
Route 3 and Valley Road Interchange
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.
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.
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
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 Relations (OCR)
NJDOT bureau acting as liaison to local officials and citizens to learn and address their concerns.
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 Interchange
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.
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.
Precise, detailed mapping of the ground surface and its features with regard to vertical and horizontal location.
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.
