National Highway System Asset Management Program

NHPP funds are required to support progress toward the achievement of performance targets established in a state’s asset management plan for the NHS.  NHS roadways encompass both local and state-owned NHS facilities, and Washington State has one of the highest percentages of locally owned NHS facilities.  Approximately 23% of the NHS routes by lane mile are owned by local agencies. The state preserves and maintains approximately 77% of the routes.  It is therefore imperative that both state and local agencies collaborate to manage the NHS; and this type of program will encourage collaboration and asset management principles across the NHS.

The main objective of the program is to highlight the importance of preserving the roadway system by incentivizing agencies to use asset management strategies that provide cost-effective solutions to maximize the life expectancy of a roadway.  To meet this objective the program will evaluate an agency’s use of pavement management strategies and an agency’s level of investment to preserve and maintain their roadway system, thereby focusing on cost-effectiveness, emphasizing pavement rehabilitation over reconstruction.

In addition, local agencies are encouraged to prioritize projects that address communities with traditionally disadvantaged populations that have faced barriers to opportunity and been disproportionately impacted by fatal and serious injury crashes.
