The Arterial Preservation Program is designed to preserve and enhance the capacity and safety of the critical transportation highways included in the Arterial Preservation Network.

These major highways accommodate long-distance mobility of people and goods throughout the commonwealth. Preserving mobility on these corridors is critical to the current and future economy.

Within the framework of the Arterial Preservation Program, VDOT is developing methodologies to consistently and programmatically evaluate the corridors through the use of Arterial Management Plans, creating a toolbox of preservation and enhancement strategies and identifying opportunities to implement these strategies.

As an alternative to widening major highways to add capacity, preservation and enhancement strategies promote the use of innovative transportation solutions, minimizing delays for through traffic and improving safety, while incorporating local economic development goals.

Developed in partnership with localities, the strategies will be used as tools to plan for infrastructure that supports future land use and development.

Arterial Preservation Network

The Arterial Preservation Network is the state-maintained portion of the National Highway System in Virginia including facilities identified by DE in concurrence with TMPD, TED, L&D and the OLU that facilitate connectivity. 

Additional facilities may be added to facilitate further connectivity through coordination of the same stakeholders should the need arise.


National Highway System – includes the Interstate Highway System as well as other roads important to the nation’s economy, defense, and mobility.

  • Interstates
  • Other Principal Arterials
  • Strategic Highway Network (STRAHNET)
  • Major Strategic Highway Connectors
  • Intermodal Connectors‌

Program Initiatives

VDOT has initiated a review of current policies and procedures to align with the goals of the Arterial Preservation Program. This review process is focused on enhancing current policies and encouraging the use of innovative strategies to preserve capacity and safety.

The review process will evaluate:

  • Current access management regulations – subject to Administrative Process Act procedures
  • Current design exception process
  • Innovative Intersection and Interchange design policies and guidance
  • Traffic signal warrants
  • VDOT’s role in project development on urban extension projects

As a result, the following policies and / or procedures have been updated so far:

  • Office of Land Use – Revisions to IIM-LU-200, IIM-LU-500, and IIM-LU-501
  • Road Design Manual – Chapter 2D, Appendix A, and Appendix F (Consideration for Innovative Intersections, state location and design engineer approval needed for new crossovers on Arterial Preservation Network)
  • Traffic Engineering Division - IIM-TE-387 (Requirements for traffic signal justification reports)
  • Transportation and Mobility Planning Division – IIM-TMPD-2.0 (Process for conducting planning studies on the Arterial Preservation Network)


Below are instructions and guidance in the deployment of the Arterial Preservation Program implementation strategies:
