Design
The Mosby Creek Bridge is Lane County’s oldest covered bridge, having been built in 1920 at a cost of $4,125 by Walter and Miller Sorenson. Spliced chords and steel rod cross-braces on the upper chords of the bridge are modifications of the basic Howe truss design. The span was capped with a corrugated metal roof. During the summer of 2002, the roof was replaced with synthetic roofing material, and other repairs were made at the same time. The Mosby Creek Bridge was one of the bridges which could be seen from the Oregon, Pacific and Eastern steam excursion train, The Goose, prior to the sale of the locomotive to Yreka, California in 1987. Design elements include semi-circular portal arches, ribbon openings at the roofline, and board-and-batten siding. Mosby Creek was named for David Mosby, a pioneer of 1853 who staked claim to 1,600 acres east of the present city of Cottage Grove.
