Fall Creek
(Pengra) Covered Bridge
Location:
From I-5 take Highway 58 east to Parkway Road. Follow Parkway Road north
to the community of Jasper. Turn southeast on Jasper-Lowell Road for about
3 miles. Turn left (east) on Little Falls Creek Road and travel 1/4 mile
to Place Road.
Background:
The Pengra Bridge contains two of the longest timbers ever cut for a bridge
in Oregon. The timbers for the lower chords, 16" x 18" x 126 feet, were
cut by the Booth-Kelly Lumber Company east of Springfield.
Since 18"
timbers were too large to be run through a mill, they were rough-hewn
in the woods, transported to the bridge site by truck and resurfaced before
being set into place. The dimensions of the upper chord are similar proportions
at 14" x 18" x 96 feet.
The use of
one-piece chords simplified construction techniques and resulted in a
stronger truss, but handling such large timbers was often difficult.
The Pengra
Bridge replaced a 192-foot span built in 1904 which had been only a few
feet upstream from the present structure. The effect of weather and increased
traffic caused the county to close the bridge in 1979.
County officials
had planned to reopen the structure, but readying a contract for work
was delayed for several years. The bridge was repaired and re-opened to
traffic by the county in 1995 with the help of a grant from the Oregon
Covered Bridge Program.
Pengra was
a station on the Cascade Line of the Southern Pacific Railroad and was
named for B. J. Pengra, a pioneer who became general surveyor of Oregon
in 1862. Pengra had surveyed the route of the Oregon Central Military
Road to link the Willamette Valley with the Owyhee mining country of Eastern
Oregon.
The road
was finished to the summit of the Cascades in 1867 but was seldom used.
The Pengra Unity Road lies on the old railroad grade and has been renamed
Place Road.
