Kinzua Bridge State Park
The 339-acre Kinzua Bridge State Park offers visitors a chance to walk the Kinzua Bridge skywalk. Located in McKean County, this park is the home of the newly reinvented Kinzua Viaduct. The Viaduct, once known as the longest and tallest railroad structure at 2,053 feet long and 301 feet high, was partially destroyed by a tornado in 2003. In 2011, the engineering masterpiece was reinvented as a new pedestrian walkway where visitors can stroll 600 feet out on the remaining support towers, peer miles out into the Kinzua Gorge as well as peer down into the partial glass platform at the end of the walkway. Picnicking and trail opportunities are available. The Kinzua Bridge Scenic Byway is a designated shared use hike/bike corridor.
Recreational Advisory: Due to unsafe conditions in the area of the downed towers, visitors are prohibited from walking under the skywalk and in the surrounding area as indicated on the map.
Scenic Views: The 300-foot high Kinzua Bridge skywalk gives great views of the viaduct and Kinzua Creek Valley. The overlook is great for viewing fall foliage, especially in the peak viewing time of the first two weeks of October. Visitors stroll the 600-foot long walkway on the remaining support towers for the best view, and to peer down through the glass at the valley floor 225 feet below.
Under the skywalk is a viewing platform for picture taking of the remaining support towers which offers an interesting “3D” effect.
Picnicking: The picnic area has shaded picnic tables and a modern restroom. A picnic pavilion with electricity may be reserved up to 11 months in advance for a fee. If unreserved it is free on a first-come, first-served basis.
Hunting: About 100 acres are open to hunting, trapping and the training of dogs during established seasons. Common game species are deer, bear and turkey. Hunting is not permitted from the bridge. Adjacent State Game Land 62 is open to hunting and general recreation.
Hunting woodchucks, also known as groundhogs, is prohibited. Dog training is only permitted from the day following Labor Day through March 31 in designated hunting areas. The Department of Conservation and Natural Resources and the Pennsylvania Game Commission rules and regulations apply. Contact the park office for ADA accessible hunting information.
Use extreme caution with firearms at all times. Other visitors use the park during hunting seasons. Firearms and archery equipment used for hunting may be uncased and ready for use only in authorized hunting areas during hunting seasons. In areas not open to hunting or during non-hunting seasons, firearms and archery equipment shall be kept in the owner's car, trailer or leased campsite. Exceptions include: law enforcement officers and individuals with a valid Pennsylvania License to Carry Firearms are authorized to carry a firearm concealed on their person while they are within a state park.
Complete information on hunting rules and regulations in Pennsylvania is available from the Pennsylvania Game Commission Web site.
The trail, through hardwood forests of black cherry and chestnut trees, includes areas both ravaged and renewed by nature itself since the 2003 tornado.

Placement of the viaduct’s stone bases began in 1881 while the ironwork and entire bridge were completed in 1882. At the time, the Kinzua Viaduct was the highest railroad viaduct in the world. It was constructed as an alternative to laying an additional eight miles of track over rough terrain along the line leading to McKean County’s coal, timber and oil lands.
Built of iron, the original viaduct was approximately 301 feet high, 2,053 feet long and weighed 3,105,000 pounds.
By 1900, it became necessary to rebuild the entire structure with steel to accommodate heavier trains. Later that year, about 100 to 150 men, working ten-hour shifts, completed the job in 105 days. The new steel viaduct had the same measurements, but now weighed 6,706,000 pounds.
Freight traffic discontinued in 1959. In 1963, Governor William Scranton signed a law that created Kinzua Bridge State Park. The park officially opened in 1970. In 1977, Kinzua Viaduct received national recognition when it was placed on the National Register of Historic Civil Engineering Landmarks.
Beginning in 1987, excursion trains traveled from Kane, Pa., through the Allegheny National Forest, stopping on Kinzua Viaduct before returning to its point of origin.
In February 2002, DCNR engineers decided the structure needed a full-scale inspection. In June, DCNR barred excursion trains from the bridge.
As the inspection continued, engineers found that sections of steel were rusted through. In August, the bridge was closed to all traffic, including pedestrians.
Engineers determined that high winds could create lateral pressure on the bridge. The wind hitting the bridge could shift the center of gravity, increasing the weight on one side. Such an event could send the whole bridge crashing to the bottom of Kinuza Creek Valley.
Beginning in February, 2003, W. M. Brode Co. of Newcomerstown, Ohio, a national leader in railroad bridge construction and repair, began working to restore Kinzua Viaduct.
On Monday, July 21, 2003, at approximately 3:15 p.m., an F1 tornado (wind speed 73 – 112 mph) struck the side of Kinzua Viaduct. Eleven towers from the center of the bridge were torn from their concrete bases and thrown to the valley floor.
Today, park visitors can once again walk a portion of the Kinzua Bridge. Built on six restored, original towers, a pedestrian walkway (skywalk) leads to a 225-foot high observation deck that gives a towering view of the Kinzua Creek Valley. A partial glass floor in the deck reveals a breathtaking glimpse into the steel structure of the bridge. The eleven twisted and scattered bridge towers blown over by the tornado remain at the bottom of the valley for visitors to view from the deck railings. Several benches line the paved walkway to the skywalk.
A grand opening was held on September 15, 2011.

We love when young people ask us how to get involved!
DiscoverE has programs for young people ages 4 to 17, provided by Pennsylvania State Park educators. By combining recreation and education, we hope to motivate children to learn more and return often, leading to a lifetime of outdoor enjoyment and conservation leadership.
In Watershed Education, teachers and students assess water quality of a local stream on a quarterly basis and develop strategies to solve local water quality problems.
ECO Camp - Exploring Careers Outdoors - is a week-long residential camp for a cross-section of high school youth from across Pennsylvania, sponsored by the Department of Conservation and Natural Resources (DCNR). Participate in action-packed, hands on activities and recreational adventures in Pennsylvania’s state parks and forests that expose youth to conservation, recreation and careers in natural resources. Learn how people make a living working in the outdoors.
