ABOUT NHX
To develop the NHX project, we’re using ODOT’s five-phase Project Planning Process. Right now, we’re concluding the initial Planning phase of the PDP and working on tasks in the Preliminary Engineering phase.
This graphic illustrates ODOT’s Project Development Process.
The Planning Phase focused on:
-
Identifying transportation problems
-
Assessing existing and future conditions
-
Identifying stakeholders
-
Gathering public input
-
Determining project scope, purpose, and goals
-
Identifying project schedule and budget
The Preliminary Engineering Phase focuses on:
-
Conducting initial technical studies, field investigations, and preliminary engineering
-
Identifying and evaluating potential project alternatives
-
Gathering public input
-
Refining information and analyses
-
Identifying a preferred alternative for construction
Next Steps
A key part of the Preliminary Engineering phase was conducting a Feasibility Study which used the results of technical studies, stakeholder input, and public input to identify and evaluate possible project route alternatives.
Once the Feasibility Study is complete this spring, the next step will be to develop an Alternative Evaluation Report (AER). The AER more closely examines each alternative advanced for further study by the Feasibility Study, as well as its potential impacts.
The AER takes the work begun in the Feasibility Study, which looked at potential alternatives at a conceptual level, and develops them in much greater detail. It’s possible that modifications to the proposed alternatives may be made during this phase.
The AER process will involve detailed technical analyses and extensive coordination with stakeholders, resource agencies, and potentially affected communities.
Upon its completion, the City, BCTID and ODOT will use the results of the AER to identify a Preferred Alternative for construction.
The Preferred Alternative
Preparation of the AER will continue through early 2024. Before the AER is finalized, another public meeting will be held to share the results of this phase of work and recommendations of a Preferred Alternative for public review. The public will also be invited to share their input before a Preferred Alternative is selected for eventual construction.
Once a Preferred Alternative is identified (likely in mid-2024), the project will advance into the Environmental Engineering and Final Engineering / Right-of-Way Acquisition phases of development.
Construction Timing
The bulk of project planning and related work (such as detailed engineering, property acquisition and utility relocations) cannot be completed until a Preferred Alternative has been identified. Consequently, it’s expected that the bulk of construction will begin no sooner than five years after a Preferred Alternative is identified. However, the NHX project will be completed in phases and some of the phased work that does not require a high level of property acquisitions and utility relocations may be able to start earlier.
Funding
Total project cost estimates will be refined as the project development process advances, and we have a better idea about what specific improvements will be made and where.
To date, enough funding has been secured to allow project planning to proceed through the Environmental Engineering Phase of project development and begin detailed design. The NHX project partners (City, BCTID, and ODOT) will continue to actively pursue additional funding for subsequent phases of project development and eventual construction.
Funding will likely come from a combination of federal, state, and local resources.
