To maintain the roads and bridges now in “good” condition—and successfully protect NPS transportation investments—the NPS must implement an aggressive preventive maintenance program. This would extend the life of these facilities, and ultimately save substantial dollars by avoiding full reconstruction costs.
Estimated replacement costs for NPS roads and bridges are approximately $20 billion, requiring an annual expenditure of between $400 million and $800 million to maintain roads and bridges. Unfortunately, historic funding levels have not kept pace with the National Resource Council (NRC) recommendations. A dollar spent today on preventive maintenance can save $3-$5 in the future, so a lack of annual investment in preventative maintenance will only cost more in the long term.
Current transportation challenges can be grouped around increased park visitation, and a growing backlog of maintenance projects and equipment needs across the 394 park units.
