The Pengra Bridge is a covered bridge near Jasper in the U.S. state of Oregon.[1] The 120-foot (37 m) Howe truss structure carries Place Road over Fall Creek in Lane County.[2] It replaced an earlier bridge, built in 1904, that crossed the creek a few feet further upsteam.[2]

Pengra Bridge was named in honor of B. J. Pengra, a government surveyor.[3] The bridge was listed on the National Register of Historic Places in 1979.[4]

The lower chords of the bridge, at 16 by 18 inches (41 by 46 cm) by 126 feet (38 m), are among the longest timbers ever used in an Oregon bridge.[2] Timbers of this size simplified some aspects of construction but required special techniques to finish and position at the site.[2] Other features of the bridge include ribbon windows under the eaves, a side window on one side, and semi-elliptical arched portals.[5]

Weather and traffic weakened the bridge over time, and it was temporarily closed in 1979. With the help of state funding from the Oregon Covered Bridge Program, the county repaired the structure, which was re-opened to traffic in 1995.[2]
