Their Numbers Dwindle
One of only two covered bridges still standing in Lawrence County, Pennsylvania, this one spans Slippery Rock Creek in McConnell's Mill State Park. Built in 1874, it employs the Howe truss system of construction and remains in excellent condition today.
Beyond the bridge and to the right, you can see the foundation of the old grist mill after which the park was named. Here's the mill: flic.kr/p/2pZgF8i.
For the spillway, please see: flic.kr/p/2q6SGJb.
