Jacks Mountain Covered Bridge, officially the G. Donald McLaughlin Memorial Covered Bridge, is a historic covered road bridge in Hamiltonban Township, Pennsylvania, spanning Tom's Creek. Built in 1890, it reflects the familiar late-19th-century rural bridge form, with a gable roof, narrow horizontal siding, and a 75-foot length suited to the modest creek crossing. Its Burr truss design, combining an arch with multiple trusses, provided added strength, while the tin-covered roof helped protect the timber structure from weather. As one of seventeen surviving covered bridges in Adams, Cumberland, and Perry Counties, it holds an important place in Pennsylvania's regional bridge heritage and was listed on the National Register of Historic Places in 1980.
