Hidden beneath a canopy of encroaching forests and weathered by decades of neglect lies a concrete ghost of America’s automotive golden age. The bypassed sections of the Pennsylvania Turnpike, often referred to by enthusiasts as the “Abandoned Turnpike,” offer a surreal glimpse into the mid-century engineering that once revolutionized East Coast travel. For hikers and urban explorers, these stretches represent a unique intersection of industrial decay and natural reclamation.
The History of the Bypassed Pike
The Pennsylvania Turnpike, which opened in 1940 as the first long-distance limited-access highway in the United States, was designed to move traffic quickly across the Appalachian Mountains. However, as vehicle volume increased and safety standards evolved, the original winding paths became bottlenecks. To improve efficiency and safety, the Pennsylvania Turnpike Commission constructed novel alignments, leaving behind several miles of original roadway.
The most notable abandoned stretches occurred during the expansion and realignment projects of the mid-to-late 20th century. These sections were not demolished but simply left to the elements. Over time, the asphalt has cracked and native Pennsylvania flora has reclaimed the lanes, turning a high-speed thoroughfare into a quiet, atmospheric corridor of ruins.
Why the Road Was Left Behind
The decision to bypass rather than renovate specific sections usually stemmed from geographic challenges. The original route navigated steep grades and sharp curves that were unsuitable for modern trucking and high-speed traffic. By building entirely new segments—often utilizing more advanced tunneling and grading techniques—the commission could maintain a continuous flow of traffic without the disruptions of a total reconstruction of the old path.
Visiting the “Old PA Pike Trail”
Even as many explorers use the colloquial term The Old PA Pike Trail
to describe these routes, these areas are not always designated as official state parks or maintained public trails. Most of the abandoned infrastructure remains the property of the Pennsylvania Turnpike Commission or adjacent private landowners.
What to Expect on the Trail
Visitors typically encounter a landscape where nature is winning the battle against concrete. Key features include:
- Overgrown Pavements: Thick layers of leaf litter and saplings pushing through the road surface.
- Weathered Guardrails: Rusted steel barriers that mark the edges of the former highway.
- Quiet Solitude: Unlike the roaring traffic of the active turnpike nearby, the abandoned sections are often eerily silent.
Legal Status and Safety Warnings
Prospective visitors must exercise caution regarding the legality of their access. Because much of the abandoned turnpike is not an official public park, entering certain sections may be considered trespassing. The decaying infrastructure presents several hazards:
- Structural Instability: Old culverts and bridge abutments may be unstable.
- Environmental Hazards: Dense brush can hide sinkholes or debris.
- Lack of Services: There are no official facilities, water sources, or emergency services on these bypassed stretches.

Camping and Overnight Stays
While some adventurous explorers document overnight stays on the abandoned turnpike, campers should be aware that unauthorized camping on Pennsylvania Turnpike Commission property is generally prohibited. Those seeking a legal overnight experience in the region are encouraged to use designated campsites managed by the Pennsylvania Department of Conservation and Natural Resources (DCNR).
For those who do venture out for day trips, the “Abandon No Trace” principle is critical. Because these areas are not regularly maintained by crews, any trash or damage left behind persists indefinitely, harming the local ecosystem.
Key Takeaways for Explorers
- Status: The abandoned sections are bypassed remnants of the original 1940s highway, not officially maintained state trails.
- Access: Entry may be restricted; always check local property boundaries to avoid trespassing.
- Environment: Expect heavy overgrowth and decaying concrete infrastructure.
- Legality: Camping is typically not permitted on these state-owned bypasses.
Frequently Asked Questions
Is the Abandoned Pennsylvania Turnpike open to the public?
There is no single “entrance” to the abandoned turnpike. While some sections are accessible via local roads or adjacent hiking trails, much of the land remains restricted. Visitors should always seek legal access points.
Where is the most famous abandoned section located?
Many explorers target the bypassed stretches in the mountainous regions of central Pennsylvania, where the contrast between the old road and the new highway is most stark.

Is it safe to hike the abandoned sections?
It can be safe if you are prepared. However, hikers should wear sturdy boots, carry a map, and be mindful of unstable ground and wildlife. It is highly recommended to hike with a partner.
Looking Ahead
As the decades pass, the abandoned Pennsylvania Turnpike will continue to fade into the forest. Whether these sections eventually become official heritage trails or are completely reclaimed by the wilderness remains to be seen. For now, they serve as a haunting reminder of the rapid evolution of American infrastructure and the inevitable persistence of nature.
