Screening Process

Level One

Screened concepts for Purpose & Need and reasonability

The study team used generalized land use, planning, geotechnical, roadway engineering, traffic, safety, and environmental data. Concepts that did not meet Purpose & Need or that had a fatal flaw (an impact or combination of impacts that prohibit a concept from being built) were eliminated. Additional Level 1 Screening details are available online:  Level 1 Screening 

Level Two

Compared concepts using qualitative and quantitative planning-level data

  1. Gathered Data. The study team gathered and analyzed refined datasets for each concept, including traffic analysis.​​​​

  2. Performed Comparative Analysis. The study team used the data to compare each concept's performance against the others, evaluating how well each concept met the study's Purpose & Need, feasibility, and goals.

Results include:

​​​

Carried Forward: Considered
reasonable and feasible, and
may be considered for further
evaluation in this study or
subsequent NEPA review and
project development.

Eliminated: Did not meet
Purpose & Need, had a fatal
flaw, or was considered
unreasonable.

Not Recommended: Will
not be evaluated further due
to comparatively negligible
benefits or higher impacts.

​​​Level Three
Will analyze concepts using performance measures to refine recommendations
Concepts carried forward may proceed into further design and the National Environmental Policy Act (NEPA) review to identify final recommendations. This study may result in several short- and long-term proposed improvements. Multiple reasonable concepts may advance and will be called alternatives in later phases, which may be funded separately through future projects.

Recap: Level 1 Screening
