The 1920 Mosby Creek Bridge, also called the Layng Bridge, is a historic Howe truss covered bridge located near Cottage Grove in Lane County, Oregon. Being the oldest covered bridge in Lane County, the bridge crosses Mosby Creek. This 90-foot (27 m) bridge was built for a cost of $4125 (US$64,746 in 2025) by Walter and Miller Sorensen. The bridge was named after the pioneer David Mosby, who settled east of present-day Cottage Grove near the current site of the bridge on a 1,600-acre land claim. Mosby Creek Covered Bridge is the only covered bridge that is still part of Cottage Grove's roadway infrastructure and supports up to 8 tons with an 11 feet 7 inches maximum height limit.

Unique design elements of the Mosby Creek Bridge include semi-circular portal arches, ribbon openings at the roofline, and board-and-batten siding, as well as modifications to the basic Howe truss design with spliced chords and steel rod cross-braces on the upper chords of the bridge.

The Mosby Creek Bridge was one of the bridges that could be seen from the Oregon, Pacific and Eastern steam excursion train, “The Goose”, before the sale of the locomotive to Yreka, California, in 1987.

In 1990, the bridge underwent a major restoration, then in 2002, the corrugated metal roof that capped the bridge's gable roof was replaced with synthetic material, as well as other repairs.

In 1979, the Mosby Creek Bridge was added to the National Register of Historic Places.
