Parvin Bridge is a historic covered bridge near Dexter, Oregon, that spans Lost Creek, a tributary of the Middle Fork Willamette River. Built in 1921, the single-lane bridge replaced an earlier Howe truss after a 1917 inspection found the older structure badly deteriorated by worm damage and likely needing replacement. Constructed by George W. Breeding for $3,617, the new bridge continued the Howe truss design and included both eastern and western approaches. Road realignment in the mid-1970s bypassed the bridge, leaving it temporarily open only to pedestrians, but after renovation it reopened to vehicles on November 17, 1986, with a 10-short-ton load limit. It is listed on the National Register of Historic Places.
