The Oregon Railway and Navigation Company Bridge is a railroad bridge in Lane County in the U.S. state of Oregon. Added to the National Register of Historic Places in 1980, it formerly carried the tracks of the Southern Pacific Transportation Company over the McKenzie River southeast of Coburg.{{cite web|last=LaRoche|first=Mark|title=Nomination Form: Oregon Railway and Navigation Company Bridge |url={{NRHP url|80003332}} |format=PDF|publisher=National Park Service|date=June 4, 1979|accessdate=January 22, 2016}} It has since become a pedestrian and bicycle bridge.{{cite book|last1=Jones|first1=Philip N.|last2=Henderson|first2=Jean|title=Bicycling the Backroads of Northwest Oregon|url=https://books.google.com/books?id=0Kb4lbPxLL4C&q=coburg+footbridge&pg=PA164|page=164|publisher=The Mountaineers Books|location=Seattle|edition=2nd|year=1992 |isbn=0-89886-340-6}} The Whipple through truss bridge, resting on concrete supports, is {{convert|405|ft|m}} long, {{convert|25|ft|m}} wide, and {{convert|44|ft|m}} high.

Built in 1887 for the Oregon Railway and Navigation Company by George S. Morison and installed over the John Day River in north-central Oregon, it was bought by the Southern Pacific in 1907 and moved to the McKenzie River by the American Bridge Company.{{cite book |title= Style & Vernacular: A Guide to the Architecture of Lane County, Oregon |publisher= Western Imprints, The Press of the Oregon Historical Society |year= 1983 |page= 111 |isbn= 0-87595-085-X}} Made of iron, it replaced a wooden covered bridge constructed at the site in 1891. The earlier bridge, {{convert|380|ft|m}} long, was one of the longest such structures ever built. It replaced the function of Spores Ferry, which began operation a short distance upstream in 1847 and was an important crossing for wagon trains.

Coburg Road crosses the river on a highway bridge next to the railway bridge, and Interstate 5 crosses on a different highway bridge slightly further upstream. Armitage County Park, about {{convert|5|mi|km|0}} north of Eugene, is along the south side of the river near the bridges.{{cite web|title=Armitage|url=http://www.lanecounty.org/Departments/PW/Parks/Pages/CountyParkDetail.aspx?ParkID=7&siteName=Armitage|publisher=Lane County|accessdate=January 22, 2016}}
