The McConnell's Mill Covered Bridge, built in 1874, stretches across Slippery Rock Creek. This wooden bridge, constructed using the Howe truss design, rests on a stone foundation and is reinforced by steel. It is one of only four remaining Howe truss bridges in Pennsylvania. The bridge was added to the National Register of Historic Places in 1980.

Daniel Kennedy opened a gristmill on Slippery Rock Creek in 1852. The mill was rebuilt after a fire in 1868. McConnell acquired the mill in 1875, replacing the waterwheel with turbines and grindstones with rolling mills, making it one of the first of its kind in the country. The mill ground various grains until it closed in 1928. The ownership passed to the Commonwealth of Pennsylvania in 1957, leading to the formal dedication of McConnells Mill State Park. Today is the mill. Today, interpretive tours of the historic mill are available at 1:00 p.m. and 2:00 p.m. in the summer. For interpretive tours for groups, call the Moraine Park office at 724-368-8811.

The trail to this fall is not on most maps, just keep walking down the gorge opposite of the North Country trail. You will have to turn around and backtrack after visiting the fall. There are some markers leading up to the falls. Be safe.
