A Short Trail to an Abandoned PA Turnpike Tunnel

The Abandoned PA Turnpike Tunnel Trail is a hidden gem for adventure seekers, history buffs, and urban explorers. This offbeat trail follows a desolate stretch of the Pennsylvania Turnpike, decommissioned in the 1960s and left to nature’s embrace. Once a bustling highway, this eerie yet fascinating path now welcomes hikers and cyclists eager to traverse its ghostly tunnels, weathered pavement, and overgrown surroundings. The experience offers an extraordinary mix of history, decay, and raw beauty, making it one of the most unique trails in Pennsylvania.

Stepping onto this trail feels like entering a post-apocalyptic world where time stands still. Towering tunnels loom ahead, their dark, cavernous interiors echoing every footstep. Graffiti-covered walls tell silent stories, while shafts of light pierce through ventilation openings, creating a cinematic glow. The contrast of abandoned infrastructure and wild overgrowth makes this spot irresistible for photographers, thrill-seekers, and anyone craving a break from ordinary hiking trails.

Unlike typical scenic routes, the Abandoned PA Turnpike Tunnel Trail immerses visitors in a forgotten chapter of American highway history. The nearly five-mile stretch, which includes the infamous Sideling Hill and Rays Hill tunnels, offers a thrilling mix of exploration and nostalgia. Whether you’re biking through the darkness or walking beneath the crumbling concrete arches, the sense of discovery never fades. With its haunting charm and surreal atmosphere, this trail isn’t just a walk in the woods—it’s an unforgettable journey through time.

The Ghost Highway’s Hidden Gem

The story of Sideling Hill Tunnel reads like a chapter from an American infrastructure epic. Located in Buchanan State Forest, this engineering marvel sits roughly halfway between Philadelphia and Pittsburgh, offering a unique glimpse into the evolution of American transportation.

• Original Construction Cost: $17 million (1940)
• Maximum Height: 23.5 feet
• Width: 23 feet

The Rise and Fall of Sideling Hill Tunnel

The Railroad Origins

In 1883, William H. Vanderbilt envisioned a railway that would challenge the Pennsylvania Railroad’s monopoly. His railroad project began carving through the Appalachian Mountains, creating nine tunnels – including Sideling Hill. However, financial troubles halted construction in 1885, leaving these tunnels unused for decades.

The Turnpike Era

When the Pennsylvania Turnpike Commission formed in 1937, they saw an opportunity in these abandoned railroad tunnels. The historical infrastructure timeline tells the story:

Year	Milestone
1937	Turnpike Commission acquires tunnels
1938	Reconstruction begins
1940	Original turnpike opens
1955	Traffic reaches capacity
1963	Bypass planning starts
1968	Tunnel abandoned

The Bypass Decision

Traffic growth in the 1960s forced a critical decision. Engineers considered several options:

1. Widening the existing tunnel
2. Building a parallel tunnel
3. Creating a bypass
4. Adding traffic control systems

The bypass won out, costing $17.2 million but promising better traffic flow and reduced maintenance.

The Abandoned PA Turnpike: A Time Capsule

Today’s abandoned Pennsylvania Turnpike stands frozen in time, stretching 13 miles through the Appalachian Mountains. When you visit, you’ll find yourself walking on the same pavement that carried countless vehicles during America’s post-war boom. The preservation of this site happened almost by accident – when the bypass opened in 1968, this section of highway simply fell silent, leaving behind a perfectly preserved slice of American transportation history.

What makes this site truly remarkable is how much original infrastructure remains intact. The old toll booths have weathered away, but you’ll still find original mile markers dotting the path, their reflective paint catching your flashlight beam. Emergency pull-offs line the tunnel’s interior, each numbered and tiled just as they were when the last car passed through. The ventilation buildings, though abandoned, still house massive fans that once cleared exhaust from thousands of passing vehicles.

Today’s abandoned PA turnpike tunnel offers visitors a unique blend of history and adventure. The site features:

Historical Elements Still Visible:

• Original mile markers
• Tunnel ventilation buildings
• Emergency pull-off areas
• Drainage systems
• Original pavement sections
• Railroad construction marks
• Vintage lighting fixtures

Original Features Still Visible	Condition	Location
Mile Markers	Partially weathered	Every mile along trail
Emergency Pull-offs	Well preserved	Inside tunnel
Ventilation Buildings	Standing structure	Both tunnel entrances
Original Pavement	Mostly intact	Entire trail length
Drainage Systems	Functional	Throughout trail
Guard Rail Posts	Rusted but stable	Trail edges
Light Fixtures	Non-functional	Tunnel interior

Planning Your Adventure

The key to an unforgettable tunnel exploration lies in timing your visit right. I’ve found that each season transforms the trail in unique ways. Spring brings carpets of wildflowers along the approach path, while fall paints the surrounding forest in brilliant reds and golds. Summer offers the most comfortable tunnel temperatures, as the constant 55-degree interior provides natural air conditioning. Winter creates stunning ice formations near the tunnel entrances, though you’ll need extra caution during frozen conditions.

Light plays a crucial role in your experience. The tunnel’s darkness is absolute – so complete that it can disorient even experienced hikers. That’s why I recommend visiting during “golden hours” – just after sunrise or before sunset. These times offer the most dramatic lighting for photographs and create stunning silhouettes of the tunnel portals.

Photography Planning

For the best shots:

Golden Hour Tips:

• Sunrise: 30 minutes before to 1 hour after
• Sunset: 1 hour before to 30 minutes after
• Portal silhouettes work best
• Long exposures most effective

Season	Best Time to Visit	Unique Features	Photography Tips
Spring	8am – 11am	Wildflowers, mild temps	Macro shots of flora
Summer	7am – 10am or 4pm – 7pm	Full tree canopy	Long exposure in tunnel
Fall	9am – 4pm	Foliage colors	Portal silhouettes
Winter	10am – 3pm	Ice formations	Dawn/dusk portal shots

Essential Trip Prep: Your Complete Guide

Don’t let the trail’s short length fool you – proper preparation makes the difference between a fascinating adventure and a uncomfortable experience. I’ve seen too many visitors arrive with just their phone flashlights, only to turn back halfway through the tunnel. The key is understanding that you’re not just taking a short walk – you’re exploring an underground structure nearly a mile and a half long.

Your Complete Guide

First, consider your lighting. You’ll need at least two sources: a primary flashlight with minimum 500 lumens and a backup. The tunnel’s darkness swallows light, so bring more than you think you’ll need. I always pack extra batteries too – the cold tunnel interior can drain them faster than usual.

Your footwear matters more than you might expect. The tunnel floor remains damp year-round, and original drainage channels can create unexpected wet spots. Waterproof hiking shoes or boots provide the best combination of grip and protection.

Essential Gear	Purpose	Recommended Specs
Primary Flashlight	Main illumination	500+ lumens, waterproof
Backup Light	Emergency use	200+ lumens, compact
Extra Batteries	Power backup	2 sets per light
Footwear	Protection & grip	Waterproof hiking shoes
Water	Hydration	1 liter per person
First Aid Kit	Emergency care	Basic kit with bandages
Camera	Documentation	Weather-sealed preferred
Warm Layer	Temperature control	Moisture-wicking fabric

Remember, cell phone service disappears completely inside the tunnel. I always tell someone my planned return time and carry a basic first aid kit. The trail might be short, but being prepared lets you focus on exploring rather than worrying about basic needs.
