Kinzua Bridge State Park

The Kinzua Viaduct was built in 1882 to carry a railroad across a broad, deep valley in northern Pennsylvania, saving a long detour around it. When it opened it was celebrated as one of the tallest railroad bridges in the world, an iron marvel of the age, and it drew sightseers even then. It was rebuilt in steel around the turn of the century to carry heavier modern trains, standing hundreds of feet above the valley floor. Rail traffic across it eventually ended, and by the late twentieth century the viaduct had become a state park attraction, with an excursion train crossing it and visitors walking its length for the view. In the early 2000s it was closed for restoration, with crews working to shore up its aging towers. Then, in July 2003, a tornado swept up the valley and struck the viaduct directly.

The storm tore several of the great towers from their concrete bases and hurled them to the ground, leaving the surviving half standing and the rest scattered in a tangle of twisted steel below. Engineers later found that the anchor bolts holding the towers had corroded, and the state chose to preserve the ruin as a monument to both the engineering that built it and the storm that broke it.

The surviving portion of the viaduct was rebuilt as a pedestrian skywalk. Visitors can walk out along the span to the point where the tornado tore it away, following the old railbed high above the valley. At the far end, a partial glass floor lets you look straight down to the ground far below, a vertigo-inducing view that draws gasps and dares.

From the end of the walk you look out over the wooded valley and down onto the fallen towers, still lying where the storm threw them, their steel bent and twisted. A hiking trail leads from the top down into the valley, where you can walk among the wreckage and grasp the sheer scale of the ironwork up close, a steep descent that means a hard climb back out.

Kinzua Bridge sits in the Pennsylvania Wilds, a vast and thinly settled region of north-central Pennsylvania covered in forest and studded with state parks, the Allegheny National Forest, and some of the darkest night skies in the eastern United States. It is elk country, timber country, and a landscape that recovered from heavy nineteenth-century logging into deep second-growth forest.

This land was long the homeland of the Seneca of the Haudenosaunee Confederacy and, earlier, other Native peoples who lived and hunted across these northern forests before displacement in the colonial and early national eras. None are federally recognized in Pennsylvania today, and descendant nations continue elsewhere. The wild forested valley the viaduct once crossed is a piece of that older northern woodland.

Spring and summer bring green to the deep valley and comfortable weather for the skywalk and the trail down to the wreckage. Summer is the busiest season, when families and rail enthusiasts come for the view, though the park rarely feels crowded in such open country.

Autumn is the showstopper, when the hardwood forest that fills the valley turns brilliant gold and crimson beneath the skywalk, drawing photographers from across the region. Winter is cold, quiet, and stark, the twisted steel dark against snow, and the high skywalk can be bitterly windy, so dress warmly and check conditions before a cold-season visit.

Kinzua Bridge State Park, in the Pennsylvania Wilds of McKean County, is home to the dramatic Kinzua Skywalk. It was built on the remains of the Kinzua Viaduct, once the longest and tallest railroad bridge in the world, which was partially destroyed by a tornado in 2003. Rather than remove the wreckage, the state reimagined the surviving towers as a stunning pedestrian walkway, creating a unique attraction that blends breathtaking scenery with a powerful story of nature's force.

The Skywalk lets you stroll about 600 feet out on the remaining bridge towers, roughly 300 feet above the valley floor, for sweeping views into the Kinzua Gorge. At the end, a partial glass-floor observation deck lets you peer straight down, a thrilling touch for those comfortable with heights. Below, you can see the collapsed towers left where the tornado hurled them, a striking reminder of the 2003 storm. An excellent visitor center adds engaging exhibits on the bridge's engineering and history.

Fall is spectacular, with peak foliage typically in the first couple of weeks of October framing the gorge in brilliant color, though it is also the busiest time, so parking fills fast, and coming midweek and early is strongly advised. The park is scenic year-round. Note that the Skywalk and trails can close during bad weather like snow, ice, thunderstorms, or high winds, so check current conditions before you go.

Yes. In addition to weather-related closures, the park and Skywalk have undergone renovation work with periodic closures, so it is important to confirm the Skywalk is open before making a special trip. Checking the park's current status ahead of time saves disappointment. When open, the paved Skywalk is quite accessible, but the glass floor and height may be uncomfortable for those very uneasy with heights, so keep that in mind.

The park sits in the Pennsylvania Wilds along the scenic Route 6 corridor, near Mount Jewett and within reach of other regional highlights, including the world-class dark skies of Cherry Springs State Park, the state's wild elk country around Benezette, and the Pennsylvania Grand Canyon at Pine Creek Gorge. Together these make north-central Pennsylvania a rewarding destination for scenery, wildlife, and stargazing, with Kinzua Bridge a memorable centerpiece.
