Project Selection

The commission approves the projects selected for this category. Projects considered in the category are evaluated on a statewide basis for inclusion in the program. Projects are grouped into three major groupings for comparison. These groups are metropolitan, urban, and rural defined as follows:

  • metropolitan - counties of 200,000 or greater population
  • urban - counties between 50,000 and 200,000 population
  • rural - counties with less than 50,000 population.

For comparison, projects are further broken down, within the major groups, into three types of projects. The three types of projects are expansion, new locations, and interchanges.

Districts receive program authority for projects that rank high enough statewide in each of the major groups and project types.

Policy

Projects are evaluated based on a cost-effective index (CEI). Consideration is given to the investment already made in a project by both TxDOT and local entities (except in those counties designated as disadvantaged by Transportation Code, Section 222.053).

Large interchange projects are selected based upon the CEI of the entire interchange. Once selected, construction may be phased over multiple years. Phases of the interchange construction will be scheduled by the Transportation Planning and Programming Division within available projected funding. Once an interchange is selected, the construction phases will not be reevaluated for cost effectiveness.

Match for preliminary engineering, construction, and right-of-way purchase/utility adjustments will be in accordance with TxDOT's Policy for Matching Funds - Participation Ratios.

Levels of authorization are assigned to the projects selected for development as part of the NHS.

  • Priority 1 - projects authorized for PS&E completion, utilities adjustments, and construction within the next four fiscal years
  • Priority 2 - projects authorized for PS&E preparation and right-of-way acquisition.
