The Trump administration and Congress have an extraordinary opportunity to provide needed and overdue resources to address the more than $11 billion infrastructure repair backlog.


Our Parks Badly Need Repairs

Our national parks, from the Grand Canyon to Gettysburg, need billions of dollars in repairs. Congress and the president must work together to fix our parks and help the local…

The National Park System is second only to the Department of Defense in the amount of infrastructure it manages, and maintaining and repairing that infrastructure requires resources — staff and materials that the National Park Service has not received from Congress.

Due to the long-term underinvestment in parks by Congress, the infrastructure repair backlog comprised of park roads, bridges, trails, historic structures, campgrounds and other facilities has grown to more than $11 billion. Over half of the projects on the infrastructure repair backlog list are park road projects, such as the Arlington Memorial Bridge and the Grand Loop Road in Yellowstone National Park.

A breakdown of the $11 billion backlog of NPS infrastructure repair needs

Pew Charitable Trusts analysis based on National Park Service data, 2015

National park infrastructure repairs and maintenance needs are funded through multiple funding sources including the operation and construction budgets determined annually by Congress through the appropriations process and guaranteed funding from the Highway Trust Fund through transportation bills. However, these funding streams have been insufficient such that in 2015, the Park Service received just 58 cents out of every dollar it needed just to keep that repairs backlog from growing.

Examples of national park infrastructure needs:

  • Yosemite National Park (California): The most pressing maintenance need at Yosemite National Park is $80 million in repairs at three wastewater treatment plants in El Portal, Wawona and Tuolumne. If these are not repaired soon, there is fear that sewage could spill into the Merced and Tuolumne Rivers.

  • Denali National Park Road (Alaska): Among Denali’s most pressing needs is maintenance on the 92-mile Denali Park Road that is the only way to access the heart of the park. The park and preserve’s buildings also need repair, including the Denali Park Kennel, which houses the only sled dogs in the National Park System. It is estimated to cost $52 million for these repairs.

  • Voyageurs National Park (Minnesota): Voyageurs National Park has approximately $4.5 million worth of deferred maintenance of nearly equal amounts in campsites, docks and trails and about $3.5 million in buildings. Several park docks are approaching 30 years of service and will require complete rebuilds.

Park fees, philanthropic donations, volunteer assistance and other sources help supplement federal funding, but ultimately the bulk of the funding needs must be met by Congress.

It’s time for Congress to provide major investments to our parks through improved annual funding and a new, more robust dedicated funding commitment to address the crumbling roads and bridges, deteriorating historic buildings, and unmaintained trails in our national parks. By investing in our national parks, Congress also invests in our local economies. Every million dollars invested in construction creates 14 to 16 jobs, many subcontracted to local communities.

Congress and the administration must make the concerted effort necessary to make a more substantial investment in addressing the most pressing infrastructure repair needs in our nation’s treasures — an estimated $4 billion out of the larger repairs backlog. This should be done as a standalone bill dedicated to national parks, combined with other conservation and historic preservation funding needs, or as a component of a broader package addressing the nation’s aging infrastructure.
