Why 13 Miles of Pennsylvania Highway Still Belong to No One

There are 13 miles of four-lane highway in Pennsylvania that nobody ever tore down and nobody guards — just abandoned in the middle of the forest with two tunnels inside. Unlike its "brother" Laurel Hill, which was turned into a secret proving ground for racing teams, Sideling Hill and Rays Hill have remained ownerless for more than 20 years since the state handed them over to a nonprofit organization. I break down: the deadly 1880s construction, the Vanderbilt-Carnegie railroad war, years of highway congestion, and why the exact same infrastructural death produced two completely different afterlives. Explore 13 miles of abandoned Pennsylvania highway that abruptly ends in the forest. See the forgotten remnants of a massive road. This video examines the mysterious stretch of abandoned Pennsylvania highway that sits untouched in the woods. While most roads are eventually reclaimed or repurposed, these 13 miles of four-lane pavement remain abandoned, complete with graffiti-covered tunnels that tell a strange story of infrastructure failure. We look at why this specific route was left to nature while other sections found new life. By examining the context of Pennsylvania history, we can trace the roots of this project back to the intense 1880s railroad wars between Vanderbilt and Carnegie. The construction of these tunnels was notoriously deadly, yet the route eventually served as a vital highway before being bypassed. We analyze the engineering specs and the unique factors that kept these highway tunnels from being demolished, offering a rare look at a piece of infrastructure frozen in time.
