Pennsylvania is home to over 200 beautiful and historic covered bridges scattered throughout the state. Of those bridges, only three remain in Pennsylvania’s Great Lakes Region, and only one still stands in Mercer County. However, for covered bridge enthusiasts, this unique bridge is well worth taking the time to visit.

Kidd’s Mill Covered Bridge is located in western Mercer County along Route 18. A few miles north of Hermitage, the county’s largest community, Kidd’s Mill Covered Bridge is located in a small park next to the road.

Kidd’s Mill Covered Bridge is unique among Pennsylvania’s covered bridges as it is the only one constructed using the Smith Cross Truss. Compared to the much more popular Burr Arch Truss, very few Smith Truss structures were ever built. While it can be hard to note the differences between a Smith Cross Truss and other similar truss systems, it is still interesting to note the uniqueness of this bridge in Pennsylvania.

The interior of Kidd’s Mill Covered Bridge shows its unique trusses.

Kidd’s Mill Covered Bridge was built by the Smith Bridge Company in 1868, just one year after Smith had patented his truss. Unlike many covered bridges, Smith built most of the bridge at his factory north of Dayton, Ohio, shipping the parts by train for assembly on site.

The bridge spans 119 feet over the Shenango River. It was restored in 1990, and while it doesn’t carry traffic anymore, it is in need of another rehabilitation, which is slated to start in late 2016 or in 2017. Right now, however, the unique interior of this bridge is filled with graffiti, making it a bit less enjoyable to see. Fortunately, the setting of the bridge is excellent, and there are many great places to take photographs around the bridge.

The inside of Kidd’s Mill Covered Bridge is unfortunately covered in graffiti.

Despite the work that needs to be done on both the interior and exterior of the bridge, Kidd’s Mill Covered Bridge is well worth visiting both because of its unique structure and because of its status as the last covered bridge in Mercer County, PA.

Parking at the bridge is quite easy as there is a large parking lot. The size of this parking lot leads me to believe that this area might also be popular with fishermen and boaters, but no one else was there when I visited to confirm this theory. Nevertheless, parking here should not be an issue.

    I see you have mentioned that there is no traffic on the bridge, but is it allowed to walk through the covered bridge? Linda

    • Jim Cheney

      Yes, you can walk through the bridge. I know that they are planning to rehab the bridge soon, so it’s possible that access may be limited for a period of time, however.

    Do you know how long the work will take? also do you know if the county will rent the bridge for a small wedding?
