The Parvin Bridge is a covered bridge located in Lane County, Oregon, U.S. near Dexter. It was built in 1921 as a single-lane bridge across Lost Creek, a tributary of the Middle Fork Willamette River. The bridge was a replacement for a Howe truss design which failed a 1917 inspection by bridge inspector J. W. McArthur. He wrote, "An old bridge. Chords badly worm eaten. Downstream chord has been reinforced in middle by a timber bolted on. Wood is but little better than a powder from worm action. All signs indicate a new bridge in from 2 to 4 years." George W. Breeding constructed the present bridge at the same site in 1921 for $3,617,〔 equivalent to $ today. It is also a Howe truss and includes a eastern approach and a western approach. Roadwork in the mid-1970s realigned the road to bypass the bridge, being accessible only to pedestrians afterwards. A dedication ceremony was held November 17, 1986 to reopen the renovated span to vehicle traffic with a load limit.〔 The Parvin Bridge is listed on the National Register of Historic Places. ==See also== * List of bridges on the National Register of Historic Places in Oregon * List of Oregon covered bridges * National Register of Historic Places listings in Lane County, Oregon 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parvin Bridge」の詳細全文を読む スポンサード リンク
