Nestled in Slippery Rock Township, Pennsylvania, McConnell’s Mill Covered Bridge has spanned Slippery Rock Creek since 1874. This historic structure features a Howe truss design, a popular 19th-century engineering method using diagonal timber members with vertical iron rods.

The bridge remains open to traffic, allowing visitors to drive through and experience its rustic charm firsthand. It sits within McConnell’s Mill State Park, surrounded by dramatic rock formations and forested gorges.

Visitor Tips: Visit during fall foliage for stunning photography. Early morning offers soft light and fewer crowds. Park at the nearby gristmill and walk to capture the bridge with the creek below. The adjacent mill and waterfall make excellent companion shots.
