National Parkways
The National Parkways subchapter in Title 16 covers one of the most distinctive ideas in federal park law: a protected scenic travel corridor rather than a single park unit anchored to one destination. The classic examples are the Natchez Trace Parkway and the Blue Ridge Parkway, both designed as long linear landscapes that combine road travel, scenery, recreation access, land-conservation buffers, and coordination with adjacent federal forest land. These laws matter because they show Congress treating the road itself, and the protected corridor around it, as a national-park resource.

What Makes a Parkway Different
A parkway is a moving landscape. The unit is not just the overlooks, trailheads, or visitor centers. It is the route, the views, the adjacent protected edge, and the controlled access pattern that keeps the drive scenic and relatively insulated from ordinary roadside strip development.
The legal design is corridor-oriented. That is why the statutes talk so much about land conveyance, easements, adjacent parcels, rights-of-way, extension routes, and transfers between Interior and Agriculture.
The parkway model links transportation and recreation. Congress wanted a drive that was itself a public-land experience, not just a means of getting somewhere else.
The Two Flagship Parkways
Natchez Trace Parkway
The Natchez Trace provisions beginning at 16 U.S.C. § 460 create the parkway from lands and easements conveyed by Mississippi, Alabama, and Tennessee. The legal focus is on assembling a continuous scenic corridor and keeping the route under federal park-style management rather than ordinary state-highway development logic.
Blue Ridge Parkway
The Blue Ridge Parkway at 16 U.S.C. § 460a-2 is the better-known modern example. It links Shenandoah and Great Smoky Mountains through a scenic ridge-line corridor running across Virginia and North Carolina, with later extension authority into Georgia. The statute reflects the complicated land status of the southern Appalachians, where parkway management intersects with adjacent national forest lands and recreational development.
How It Works
The parkways depend on a structural feature that distinguishes them from most NPS units: donated land and easements from state governments made the initial corridors possible, and ongoing protection depends on controlling the adjacent landscape. The Blue Ridge Parkway and Natchez Trace Parkway enabling acts both included authority to acquire contiguous parcels — not just the road corridor itself — because unconsolidated ownership in the surrounding area would undermine the scenic and recreational purpose. Limited access is integral to the statutory design: permit and license authority for crossings and access points reflects the idea that uncontrolled road connections would fragment the parkway's character; the parkways are not just linear scenic highways but managed corridors where the experience depends on maintaining continuity and separation from surrounding development. The Blue Ridge provisions also build in explicit coordination with the Forest Service, reflecting the reality that the parkway's southern sections run through national forest land — the management boundary between NPS and USFS is not a hard wall but a seam requiring ongoing interagency coordination.
By the Numbers
- Blue Ridge Parkway: 469 miles from Shenandoah National Park in Virginia to Great Smoky Mountains National Park in North Carolina; the most visited unit in the entire National Park System most years, with 15–16 million visitors annually (more than Yellowstone, Grand Canyon, and Yosemite combined)
- Natchez Trace Parkway: 444 miles from Natchez, Mississippi, to Nashville, Tennessee; approximately 6 million visitors/year
- Deferred maintenance — Blue Ridge Parkway: Over $500 million in deferred maintenance as of 2024, the largest backlog of any individual NPS unit; includes road surface, tunnel rehabilitation, bridge repair, and visitor facility work accumulated over decades of underfunding
- Economic contribution: The Blue Ridge Parkway generates an estimated $924 million in economic activity in surrounding communities annually, according to NPS economic impact reports; the Natchez Trace generates approximately $234 million
How It Affects You
<!-- pria:personalize type="impact" -->If you drive these routes for recreation: The Blue Ridge Parkway's 469-mile corridor is closed to commercial vehicles, lacks development corridors, and limits access to prevent the roadside strip development that characterizes ordinary highways. This design is entirely a product of the parkway's federal park status under these statutes — without the NPS authority defined here, the Blue Ridge Parkway would be managed as a state highway and would look very different. Seasonal closures (typically portions of the Parkway close in winter due to ice), temporary closures after storm damage, and construction-related lane closures are managed by NPS, not state DOTs.
If you own property adjacent to a parkway: The corridor-protection design means adjacent development is regulated to protect views and scenic character. NPS has easement authority along these corridors; some adjacent landowners are bound by scenic easements that limit what they can build or modify on their property, even if they own it outright. Check with NPS if you're purchasing land near either parkway — encumbrances affecting visible structures, lighting, or large-scale clearing may be part of the property record.
If you're a local business or municipal government near the Blue Ridge Parkway: Your economy is meaningfully tied to Parkway visitor traffic — the $924 million annual economic contribution flows mostly to gateway communities in Virginia and North Carolina. The Parkway's deferred maintenance backlog (over $500 million) directly affects your visitors' experience: deteriorating overlooks, rough road surfaces, and closed facilities reduce dwell time and visitor spending. Advocacy for Great American Outdoors Act funding and EXPLORE Act implementation is economically relevant for these communities.
If you follow federal lands and infrastructure policy: National parkways are a test case for the collision between the Great American Outdoors Act (2020) — which dedicated up to $1.9 billion/year for five years for deferred maintenance on NPS, USFS, and other federal lands — and the accumulated infrastructure deficit of managed park corridors. The Blue Ridge Parkway alone accounts for a significant share of the NPS maintenance backlog; tracking GAOA funding applications to the Parkway is a proxy for whether the Act's ambitions are translating into actual project execution.
<!-- /pria:personalize -->State Variations
These are federal park units, but the local setting matters significantly:
- Virginia and North Carolina (Blue Ridge Parkway): NPS manages the 469-mile corridor; adjacent Pisgah and George Washington/Jefferson National Forests create a patchwork of federal land that complicates local zoning near the Parkway; gateway communities like Boone, Asheville, and Waynesboro are economically dependent on Parkway traffic
- Mississippi, Alabama, and Tennessee (Natchez Trace): The Trace's agricultural and archaeological character requires different management than the mountainous Blue Ridge; interpretive programs on Native American trade routes and early American history give the corridor a different visitor experience and different educational programming needs
- Adjacent development pressure: The Blue Ridge Parkway faces intense development pressure near Asheville and other growing mountain communities; the Natchez Trace faces less pressure in most segments but has specific flash points near Nashville and Jackson
Recent Developments
The most significant operational event affecting both parkways in recent years was the destruction caused by Hurricane Helene in late September 2024, which caused catastrophic damage to western North Carolina — a region the Blue Ridge Parkway traverses. Flooding, landslides, and road washouts closed large segments of the Parkway for weeks, severely disrupting fall foliage season, which is the highest-traffic period for the corridor. NPS estimated tens of millions of dollars in Parkway damage from Helene; full restoration of some segments extends into 2025-2026. The disaster accelerated conversations about climate resilience investment for the aging Parkway infrastructure.
The Great American Outdoors Act (2020) created the first dedicated, mandatory funding stream for federal land deferred maintenance — up to $1.9 billion/year for five years, split across NPS, USFS, BLM, and other agencies. Blue Ridge Parkway has been among the NPS units receiving GAOA funding for road rehabilitation, tunnel improvements, and bridge work. But $500+ million in total deferred maintenance means GAOA funding addresses the backlog incrementally rather than closing it.
The Trump administration's 2025 NPS workforce reductions — buyout offers accepted by hundreds of NPS employees, including rangers and maintenance staff at both parkways — raised concerns about the ability to maintain safety patrols, respond to emergencies, and keep visitor facilities open during peak seasons. Both the Blue Ridge and Natchez Trace parkways operate with visitor centers and ranger programs that depend on staffing levels that had already been reduced through years of underhiring before the 2025 reductions.
