The 1920 Grave Creek Bridge is a covered bridge located in Josephine County, Oregon carrying Sunny Valley Loop Road over Grave Creek. Originally the bridge carried U.S. Route 99, the Pacific Highway over Grave Creek. Being the only remaining covered bridge in Josephine County, it is "Oregon's most viewed covered bridge" because of its location near I-5.

In the fall of 1846, the first emigrant train from Fort Hall, Idaho, to travel the southern route to the Willamette Valley camped on the north side of this creek, then Woodpile Creek. Martha Leland Crowley, 16 years old, died of typhoid fever during this encampment and was buried 150 feet north of the creek on the east side of a white oak tree that was later removed for the present roadway. Thus, the name "Grave Creek."

When James H. Twogood laid out his land claim in the fall of 1851 and filed it on May 1st, 1852, he named it the Grave Creek Ranch in memory of that unfortunate incident. McDonough Harkness, his partner, was the first postmaster of Josephine County in the newly named town of Leland on March 28, 1855. Harkness was killed by the Indians in April 1856 while riding dispatch for the Army during the second Indian War of southern Oregon, which started in October of 1855.

This 105-foot (32 m) Howe truss bridge features six Gothic windows on each side as well as rounded portals and a shake roof. Existing records on the Grave Creek Bridge show a contract awarded by the Oregon State Highway Department to J. Elmer Nelson and A. A. Clausen in April 1920. Just four months later, traffic passed through its portals. The truss is supported by "dumbbell" concrete piers. The total cost of the construction, including the engineering fees, is listed at $21,128.

When Interstate 5 was built nearby, ownership and maintenance of the Sunny Valley Loop Road, which includes Grave Creek Bridge, passed to Josephine County. In the late 1990s, the bridge was closed to traffic and was reopened in 2001 after repairs to the approaches and housing.

Grave Creek Bridge was added to the National Register of Historic Places in 1979.
